The whole "you will see more wildlife in 10 minutes underwater then 10 hours on land" thing is so incredibly true its not funny. You can literally see an entire reef ecosystem in your limited masked field of vision. From the plants all the way up to the predatory fish. And you can do so without even being seen as an outsider or scaring stuff away.

Im mostly a free diver. Ive scuba dove for years. But I prefer the additional freedom, tranquility, relaxation, physical challenge, mental challenge, and simplicity of free diving. Not that scuba doesn't have its own challenges, I just prefer the types that free diving presents. I am also big into spearfishing. The satisfaction of cooking meals for your friends and family that you went out and caught yourself for free is awesome.

I scuba and freedive in Southeast Florida, USA . Mostly in Broward, also in miami/the keys sometimes. I go diving any chance I get. Which is usually the weekends. Here are some photos and a video I've taken recently. If you have a chance, go diving!

Mornings just ON the ocean are often magical:

Sometimes dolphins come and say sup. Then run away when you want to play:

Then you swim down and get to see stuff like this:

Then think you are cool because you have a gun:

Intro free divers start around five minutes, then progress to about ten. Expert free divers can push that into the 15 minute range, and the world record is just shy of 20. Pretty incredible.

Those numbers are very high. An into freediver in a class using specific breathing techniques (that can be a bit dangerous) may reach 5 minutes doing "static apnea" (laying face down in a pool perfectly still) if he is in shape/naturally good at it. But 2-3 minutes is common for starters. A beginner doing "dynamic apnea" (aka swimming, finning, or pulling) will probably have a breath hold of under 1 minute.

Expert/training freedivers can hold their breath in static apnea for 5-10 minutes. with 11.5 being the current record. Again, this is lying 100% still. In dynamic those numbers go way down with experts in the 3-5 minute range depending on the type of dive. For instance, in that video, they used scooters to get down to the wreck so they didn't waste oxygen (that is why they can climb all over it 100 feet down)

The 15 and 20 minute numbers you are reading is a static breath hold with the use of 100% oxygen breathing for a long time before (this would kill you if you dove deep while doing it).

You mention free divers use weights to descend quickly... doesn't that slow them down on the way up?

It must take a lot of practice to know when to surface. As an untrained pleb, my reflex only tells me when I need to breathe RIGHT loving NOW. I can't imagine swimming up dozens of feet to the surface without panicking.


Freedivers don't exactly use weights to "decend quickly" unless were talking about the using of sleds or drop weights to get down very quickly. Which is really only practiced by competitive freedivers and pearl/sponge divers. And in those cases the weight is left at the bottom so they can surface quickly.

Freedivers usually use weight to balance out the buoyancy of their wetsuits. A 3mm wetsuit can make you float like a cork, not to even mention 5 and 7mm suits for colder climates. Some degree of flotation on the surface is required (being "negatively boyuant" on the surface is extremely! dangerous). But ideally as a freediver you want to float on the surface and become "neutrally buoyant" at between 20 and 30 feet. This is usually where your body naturally becomes neutral naturally without wearing a wetsuit. But people with different body types float differently.

So TLDR weight are used to make it "easy to get down, and easy to get up" Not enough and you can't get down. Too much and you can't get back.

Great OP. I still wouldn't mind seeing a section about where all our goon divers are located for potential dive meetup purposes. I'm in Orlando and don't mind travelling a few hours to make a dive. I've dove in Jupiter a few times now.


If you want to see some crazy free diving, check out this video. This just blows my mind.

Yes my favorite freediver ever. William Trubridge. He is amazing I love diving CNF (constant weight no fins) like in this video. But my max depth is about 15 meters / one minute because I never practice. A 4 minute dive time is insane.

Here is a pretty good article partially about how hard William Trubridge dominates. And partially about a freediving competiton. But be wary, the reporter went to a competition with some abnormally bad blackouts and accidents. So he sort of freaked out and sensationalized the article a bit. Its otherwise a pretty good read.

As I said in my other post. Those near 20 Minute record breath holds are with oxygen breathing assistance. A normal breath of air is only 21% oxygen. Hence the superhuman abilities.

Agreed, I clip mine to the D-ring on my left shoulder strap. There is just enough slack to where I can read everything with it still clipped, but not enough to where it's swinging about.

Question related to freediving/snorkeling with a wetsuit. How much weight would you need to balance out a 3mm wetsuit roughly? I'm assuming just a few lbs. I've never worn weight when snorkeling/pseudo-freediving, but I've never done it with a wetsuit. I'm going to be passing through Venice, FL tomorrow and figured I'd swing by the beach and go dive for some shark teeth off the coast.

It depends a good deal on bodyfat, lung capacity, and the exact makeup of the suit (2piece or not, hooded or not, etc). But people generally use around 10lbs of weight to become neutral at 20-30ft in a 3mm wetsuit.

IM FROM THE FUTURE

rockcity posted:

It's a one piece, non-hooded wetsuit. I don't think I'll really be going that deep on this venture though. Most of the shark teeth are in shallow water from what I've read. I'd wager I'll probably be closer to the 10 ft range. I'm going to bring my whole set of weights with me to find out how much is comfortable for me.

If you are diving shallow you can weight yourself towards the lower end of that 20-30ft number. But I wouldn't go too far beyond it.Maybe at most enough weight to be neutral at 15ft or so. Even if you are diving 10ft and it means never going neutral. Any more weigh then that and you will be too heavy on the surface, which is both dangerous and annoying (you will sink every time you exhale).

I would like to become better at free diving because my husband is a huge fan, 80 feet max depth. But I am a pussy and shoot straight back to the surface at the first hint of an urge to breathe. I'm been trying to hit 20 feet for 3 years now.

Can this be overcome--are there techniques you can use to make that "hey I need to breathe" feeling not so strong? Or is it just something you're born with because of lung capacity or something?

I really prefer the tank but I would like to see what it is about freediving that gives my husband such a hardon.

Second question--I moved to Massachusetts after living in American Samoa for several years. Is it even worth trying SCUBA here?

There are 3 main factors in being good at freediving. They are basically:

Mental: Relaxation is absolutely key in freediving. Relaxing before the dive, staying calm during the dive, and having confidence in your abilities can really go a long way towards diving deeper. Its also important to not mentally translate that urge to breath into stress and anxiety as it tries to naturally do. This is something that takes practice.

Technical: Your lungs provide a limited amount of energy for a dive. As you dive you "spend" that energy. The harder you work, the quicker you spend, the quicker you run out. Using techniques (or gear) to make your body hydrodynamic and your fin-stroke more efficient means less work gets you deeper. For instance, I can rattle off 5 mistakes most people make in technique that greatly diminish their freediving ability by wasting energy. 1) looking down on the dive instead of foward increasing drag on your body 2) diving at an angle instead of straight down at 90* to the surface 3) Flailing fins in the air during the duck dive instead of waiting until your fins are submerged to kick 4) Thinking that "faster is better" when it comes to finning. Its more important to be efficient then to be quick 5) Being weighted incorrectly and fighting buoyancy.

Physical: This is the hard part. Its a mixture of natural physical ability, and just plain old training hard. There are many physical factors that determine and effect how well we can hold our breath. Lung capacity and diaphragmatic flexibily, cardiovascular fitness and muscular strength, dive reflex activation etc. Some people are born with more of this, but anyone can work for it and be amazing. The best training for all of the factors I listed is freediving. Second to that, diving in pools or doing simulated "apnea walking". But a longer breath hold just takes time, patience, and practice.

You dont want to train yourself to ignore the urge to breath. You want to train your body to consume air so slowly that it takes say 60 second at 60 feet for that urge to exist. If you train your body to ignore that signal, you are essentially training yourself to black out.

Competitive freedivers battle through and train to ignore that urge to the point where many have chest contractions during dives. But this is not something that recreational freedivers should be thinking about.

I've had my cert for nearly 10 years (I'm 25) but only went with my dad who paid for everything and we always rented everything, all I own is mask/fins/snorkel. And don't know that much about diving except i friggin love it. I've dove maybe 6-10 times ish? Well, I live in Miami now and have only gone diving once since I moved down here (pathetic), and rented from the shop. it was 120 for all gear plus two tank dive. I'm a PADI open water. I want to buy my own gear and start diving more, both around Miami and the keys. However, I know nothing about gear. What mil wetsuit should i get? used gear, or new? I saw that link for scubatoys, the midline package looked pretty good. Any advice would be great. Also always looking for a dive buddy!

Like crunkjuice said, "comfortable" wetsuit thickness is quite varied. But I am from SE florida and will give you my opinion on what works for me.

Through the months of about may-oct no wetsuit is needed at all. I dive in a rashguard or bathing suit.

Between oct-may a 3mil wetsuit will be good about 80% of the time. The other 20% when cold fronts come through and get the water temp down you need either a "5/3/1" (thick in the body thinner on the arms), a full 5mil suit, or a hood and vest to go on top of the 3mil.

There is a feeling among some divers that diving shouldn't be accessible. I think it usually boils down to wanting to feel badass for being a SCUBA diver. If some fat lady at a resort can do it, they feel it makes their diving less impressive. I think the macho attitude is a big reason why the dive community (at least in my area) skews so heavily male.

PADI gets a lot of flak because they're the biggest player and because they cater to new/casual divers. I'm sure there are many other, legitimate, reasons to dislike PADI, but in my experience that's what most of it has boiled down to.

In my experience the instructor matters 100 times more than the certifying agency. If one shop offers both agencies it's probably the same instructor anyway, so it doesn't really matter.

I don't think pretentiousness is the only reason people are uneasy with how easy it can be to become certified (and stay certified despite forgetting everything). Just reading scubaboard's accident section quite often highlights the danger of thinking that scuba diving should be above all "easy and accessible". Diving is fun and safe, but it requires a floor level of training, knowledge, and skills, to really be safe. If it comes down to individual instructors providing better instruction over and above the curriculum to keep people safe there is in my opinion room for improvement in the curriculum. And as far as ive seen, NAUI does a bit better job of testing that divers are prepared. But in the end, its in the hands of individual divers to know they are diving safe.

Padi is also way more "accepted" around the world. probably 80% of the world is "padi padi padi" so if you plan to travel...

And what does "accepted" mean? You don't need a PADI card to travel. The only real benefit is that a PADI resort/dive op can look you up if you don't have your PADI card. Honestly if you show up with a card that says you're a scuba diver that isn't done in crayon on construction paper you're probably fine. I joked about using my NAUI card when traveling rather than my PADI ones because it doesn't have a number on it, but they never question its validity, only that they have a form that they have to put a non-existent diver number in.

The instructor is the most important factor in where to train. Given a good instructor, I'd probably prefer NAUI over PADI since NAUI's syllabus is more open to instructor discretion (at least as it was explained to me by someone with both instructor cards).

"Accepted" means that all these places around the world that are PADI will better understand your current level of certification. They also usually offer the ability to continue your diving education in the padi system. So while im sure they accept you enough to fill your air and take you on dives if you have a card that looks half legit. Its still not as "accepted" as padi divers diving with a padi dive shop.

For instance, the name for the NAUI open water diver cert is the same as the PADI "I only did half my open water and need to be watched" cert.

The NAUI card being called Scuba Diver predates PADI's very existence. It also states quite plainly on the card that the person is Open Water certified. If a dive operator can't understand that very basic concept I am not sure I would trust them to even tie their own shoes properly much less get to me to a dive site safely.

It really does not matter what agency your certification was through. The instructor is far more important than the agency. You can also have a Naui Scuba Diver card and take an SSI Nitrox or Padi Rescue and vice versa. Padi HQ even states that PADI shops should accept Universal Openwater Referrals. The agency is really not all that big of a deal for the consumer. It gets to be somewhat of an issue once you hit the professional level and are deciding which agency you would like to teach through.

Padi probably did it just to be dicks. And yeah, I wouldn't go diving with guides of that caliber, but people seem to do it every day on vacation in poorer countries.

I totally agree its the instructor more then the agency. And I wasn't aware you could cross train with different cert's and they were counted as equivalent.

Whats the max water temp you can use a dry suit? I can imagine it being pretty hot and sticky in there.

Did some wreck diving on Saturday and Sunday. Both dives were about 90 minutes surface to surface. I almost ran out of line on my 400ft reel on one penetration which is cool or disconcerting depending on how you look at it.

I dove an Evolution+ rebreather today and it's a cool unit. Trims out real nice. My only complaint about it that the bailout valve is a bit awkward and just dosen't feel well constructed. More generally, I'm so used to holding my breath when I get my buoyancy perfectly dialed in (before passing through a tight restriction or something) that I did it out of habit a few times which messes you up on a rebrerather. I'm taking it to a wreck diving sometime this week so we'll see how that works out.

Weather is not cooperating for some of the more aggressive dives but I've got almost a week to see if things clear up. On that subject: the snorkeling boats in Key Largo can be pretty evil. They go out pretty much regardless of weather, taking people who probably aren't used to being in rough seas to sites that have poo poo visibility because of how shallow they are. I saw a boat coming in earlier full of people that... did not look very excited about their experience.

Man, that is pretty terrible. Not only do rough seas suck, but low vis snorkeling can be pretty terrifying for people who aren't experienced. I was out this weekend in Fort Lauderdale and the Viz was horrible. Couldn't see bottom in 20fsw. Mostly went fishing but got some diving in later in the day. Viz waslow enough to make hunting hard, and the only nice fish I put a shot on was too quick.

I am likely going on a rough boat tomorrow. I wonder if the length of rope + bucket will be needed to horse trough the vomit for people. Failing that it goes full blown shomit I will get video promise if that happens!


Rough seas are not so much what sucks, what sucks is visibility. But Terrifying is better than vomit there is a level of truth to this. You get somebody scared enough they wont poo poo or puke.

What mechanism makes holding your breath to maintain an exact buoyancy not work on a rebreather?

Tell them to wait until the dive to puke, no reason to let free chum go to waste.

The last time someone I know puked they got attacked be a few remoras, it was absolutely hilarious watching the 3 of them trying to attach to his body while he desperately defended himself while puking and making them more interested.

Never ever ever ever hold your breath while breathing any compressed gas at depth no matter what. You can have an over expansion injury with even a pressure change of a few feet. It does not take much to damage the alveolar membrane.

Bishop- that's too bad about the weather. It's kind of par for the course for the keys in late winter and early spring though. You might get lucky though because the weather can turn around I what seems like minutes.

I know you aren't supposed to, and I understand the dangers of lung over expansion injuries. But I do it every so often while lobster diving if I need to do some precise hovering with my hands in a hole. I only do it in those instances where im absolutely certain im not changing depth at all. I also do it in a way that's more exhaling imperceptibly slow then "holding" my breath (keeping the airway open). I dont think there is much risk in that, and it beats some other lovely lobster divers solutions of going negative and standing all over the reef for support.

Going out, swimming off the beach to hunt dinner completely under your own power. On a beautiful reef in a sustainable fishery. Then going home and making an incredible and otherwise expensive meal for the cost of the seasonings. Is probably the greatest thing I've ever done or will ever do.

Right, and I just mean with that particular head-strap. It feels secure and hard to not notice coming off your head. But under water it seems to quietly sneak away when people are distracted with important diving stuff. I know like 2-3 people who have lost them that way. Now they just bolt it to the mask.

My current problem with my GoPro, though: I tried to change the lens out for a flat lens, and somehow stripped one of the screws in the process. I can get all of them out but one, and I still haven't replaced the lens, so my one experience underwater is just a big blurry mess. I tried the 'put a rubber band on the screw" trick, and all the things I've found on the internet are like "use a power drill!", but I obviously don't want to do that near the lens and such. Does anyone have any tips?

If one of the screws is damaged I would say there is a high probability that case is hosed. Even just 60 feet down those little seals get the poo poo squeezed out of them, I dont know If I would trust the side without the screw to hold up. But you can always install and do a dive without the camera inside to find out.

If it is hosed you can get a flat lens+housing for eyeofmine for only $80

I'm planning on getting one within the next few months and was considering doing a bolt on to my mask too.

My Oceanic is frameless so there's really nothing good to mount it to on that one.

Yes and not only that the skirt needs to be attached to the front, not the sides of the frame. But not all masks are like this. Another good options is a small lanyard you can attach to your mask strap.

well, when you said "stripped" I assumed that the plastic threads were stripped from the housing. Meaning even if you got the screw out, another screw in its place would simply slip in and not have anything to bite.

It makes navigating the reefs here an absolute bitch, because there are often 30-40 foot gaps between patches of reef. But I think its kinda cool to just look down and see nothing.

Anyone ever dive in deep water, like 400-600 feet? That is pretty freaky. You can see for a long while in every direction, but its just a glowing blue. Ive done some 30-60ft freedives spearfishing for mahi and its a pretty crazy experience.

I think that, once I get the screw out of there, it should be fine. The issue is that the top is stripped, so I can't get it out. Most things I've seen regarding how to remove a stripped screw involve power tools and lots of pressure, but when dealing with a waterproof plastic camera housing, specifically the thin part with the lens housing, and screws that are like a millimeter tall, that's probably not an option.

This isn't the screws in question obviously, but that's basically my problem in a nutshell.

I get what your issue is now(the head is stripped not the threads). To get that little ittybitty screw out without damaging the plastic ring sounds nearly impossible. If I was in your position I would probably attempt to delicately dremel a slot into the head of the screw. But this would more then likely just mean the end of the plastic ring, which im sure is replaceable, but not readily.

Wouldnt it maybe be better to get your cert before and not during the trip? Even if it meant certified in a dirty quarry somewhere. Not only will you probably receive better more personal instruction in a smaller non-vacation class setting, but you will have more time to focus on the incredible destination when you are there.

Im with everyone else on the whole DIR thing. Lots of stuff that seems like everyone could benefit from ( hogartharian like rig, having non horrible trim, doing things alike with your buddies, sticking with your buddy, knowing how to fin) but too many practitioners take it to an all or nothing extreme that turns people off. Especially if you are in 30 feet of open water and not a cave. I mean, isnt that one of the core concepts of "DIR" that the complete system itself is most important and youre either 100% "DIR" or youre doing it wrong.

This poo poo is absolutely not something you need to worry about when doing normal diving.


Yes, this is a good thing to point out. It seems the media never gets that one right when 02 bottles explode. They always call them "scuba tanks" causing people to ask me if im worried about my air tanks exploding.

Scuba tanks are only filled "air" which is 21% oxygen 79% nitrogen oxygen and cant explode. Just like earf.

What O2% was that reg rated for?

Yall a bunch of snorkel haterz. Of course as a freediver I love snorkels, I have a nice collection going. But they are all just simple J's because those are the best and purges and floats and ballvalves and whatever suck and are gimmicks. Although, purges are great if you like drinking seawater.

My favorite for diving in big seas is the cressi california. And the best foldup is a rolled up cressi corsica.


Speaking of caves have you guys ever read Sheck Exley's Caverns measureless to man? I did and holy poo poo is it an awesome/crazy book.

Ill be diving every chance I get this summer mostly in broward with a few trips to the keys and the west coast of florida. Probably mostly freediving. But some hookah and scuba here and there.

May first is the Atlantic grouper season opener, trying to make it down to Elliot Key the first weekend of may to get some nice opening weekend grouper sandwiches. Will also be hitting the deeper wrecks and grouper holes up here in broward.

July 25th and 26th is lobster mini season. Per family tradition I will be going down to big pine key for both days to catch lobster and have fun.

Rockcity, do you have any more info about the shark-tooth diving? I am super interested in getting some megaldon teeth sometime soon.

Does anyone have any dive light recommendations? I'm going to be taking a cavern class soon and my buddy who is going to be the instructor told me I should get three lights, two smaller clip on style lights and one brighter wrist mounted one. I've only used a couple lights before, one was a pistol style light I used over a decade ago for general night dive use and the other was a small Intova that I borrowed from said instructor buddy for diving through a hole in a reef.

Heading down to Venice, FL this weekend to do a shark teeth dive, I better not get washed out by waves again. In the past month I've had two dives scrubbed because of big waves.

I do know that many people prefer clip on lights of the twist on style vs the switched style because of the durability and simplicity of the twist ones.

Wind and waves have been absolute poo poo here too. Atleast on days im not working. Was trying to go down to the keys for a weekend filled with birthday diving, but now the forecast is calling for crap conditions cause of the front.

SlicerDicer, I think I have the same reaction to your re-breather stories as non aquatic people do to my freediving stories.

Yeah, in good vis you don't need a cutting beal. Still, the more powerful the light, the brighter the wide beam will be.

The dorcie backup light is really good, a LOT of tech people use it as their backup light around here. http://www.amazon.com/Dorcy-41-1467-Lumen-Super-Submersible/dp/B0023RSXSO Its a little underpowered for a primary, but its a good backup for any level of diving.


Until i got the Sola 1200 new for 180 bucks i used this.http://www.dealextreme.com/p/diving-cree-ssc-p7-c-sxo-3-mode-900-lumen-led-flashlight-kit-2-18650-4-cr123a-4-16340-29069?item=28 Its a badass flashlight for 75 bucks, and puts out light comparable to something 4-5x the price. I put it through 80 dives with no floods, down to 130 feet. It doesn't put out 900 lumens, but is brighter than 500 for sure. It cuts through lake travis muck really well and is like a sun in clear water.

That things looks pretty rad.

I need something with a small cutting beam for bad viz and looking in holes deep holes. I just bought a new dinky led light and its usuless with a too-wide wide beam. Is the beam on that light you posted thin?

Well I am reading of massive helium shortages.. Can anybody confirm? I am going to make some calls tonight

People are quickly using up all the helium we have on earth. Any shortages we see now are just early indicators of our bleak heliumless future.

Underwater photography is hard, I believe. I do know for a fact, though, that it is even harder when you are a rank rear end amateur with 12 dives since your open water certification and you are using a point and shoot in a case. But, gently caress that, its still fun!

Sometimes you see a lobster and realize that they have redeye problems like people too, only not red.



Sometimes you see a shark and actually get a good picture. Well, except for the fact that the point and shoot flash does nothing for loss of color at depth and the spots on the inside off the camera housing that I keep meaning to clean off and forgetting to follow up on. Except for those things, you sometimes get one you are happy with.


Sometimes you see something cool, like a barracuda with its mouth open and then you are too much of a slow uncoordinated idiot to capture it in time, so you get an out of focus closed mouth shot.


You may try to make up for it by getting close enough that it opens its mouth again (or just partially close, use zoom, and hope to get stupid lucky).


But, photography challenges notwithstanding, diving the wall off of West Caicos has be awesome. I find it quite inspirational! And my wife's having fun diving too, so there will be at least four more chances for me to take terrible pictures. Also, we're about to go out drinking and eating jerk chicken with a live reggae band. I only have one reaction to that!

TCI is awesome, dive here. And Caicos Adventures has been great so far, except I have a feeling all of our dives will be near West Caicos. That's okay, though, the wall owns.

Cool pics. Welcome to your new money drain/obsession. A quick and dirty secret I personally love for badly lit underwater photos is using the "auto tone" option in photoshop. It really un-does a lot of the blue filtering you get. I did it to two of your photos as an example.

Just found this thread.... Sweet Pursuit fins - I've bought some gear from Dan but haven't pulled the trigger on the carbon fibers yet. I'm still a spearfishing rookie, so the $$ has been better spent on other gear.

I'm heading down to Big Pine Key in about a week - If you have some good spots/coordinates you want to share let me know. Last year we had a great time on Looe Key, but are looking to expand our horizons this year. Like to a place where I can introduce some fish to my speargun...

Awesome! Dan's the man. Ive bought most of my gear from him for a while. He sells no nonsense spearfishing gear for the best price he can. Do you live down here in FL or are you coming down for vacation?

The carbon fins are definitely a few bucks, but I wouldnt trade them for the world. Plastic long fins like gara3000's are pretty good as well. But A good pair of fins is probably the #1 most important piece of gear if you ask me. The easier it is to swim, the deeper and longer you dive, the more fish you see.

Im familiar with the big pine area but more so for lobstering and more so the bridges of spanish harbour and bahia honda then anything else. I lobster dive there every year but usually spear further north. I think Ive got some numbers I can pull off my GPS so I will take a look.

A big easy one is the island just southeast of bahia honda park. Ive heard it called "hog island" by some and shot a few nice ones there in shallow waters around the island. The pilings in those bridges I mentioned have some serious grey snapper honeyholes aswell (spanish harbour esp) under some of the really ledgy pilings. But be careful of strong currents and sharks though. You can only dive it at slack tides easily.

If the viz is right drifting and towing in a depth youre comfortable at can pay off hugely. You can find nice patch reefs, coral heads holding big groupers etc by just looking around and keeping your face in the water. How long are you gonna be down there spearfishing?

Heres some video I shot a few weeks ago. Went to elliot key with the family and did some real shallow spearing. Got A nice hog and two nice groupers. They were eaten that night with the hog cooked whole and they tasted absolutely exquisite.

Would you guys suggest DAN insurance? It seems like a pretty good deal, 75 bucks a year or so. I borrowed a friend's PADI "Adventures in Diving" textbook and started reading up on the deep water diving...I'll admit it has me a little spooked.

1000 yes's if you do any kind of diving pretty much.

Yeah, I have a few pictures of lionfish too and keep wondering if I should kill them instead of photographing them. Or maybe both?

Those things are gonna wreck the Caribbean, aren't they?

If you have the means, always kill every one you see. Its not gonna help a ton. But its better then nothing.

If its decent size, keep it and eat it. Bring some shears to cut the spines off in the water. They make delicious civiche and fried invasive nuggets.

Dont get stabbed. Its way worse then jelly/manowar/firecoral/bristleworm

So many have been killed here I barely see them at recreation depths anymore. Too bad there is billions in 200+ feet

Gonna be going down to the keys (staying in big pine) for Lobster Mini Season. Tue-Friday. To say I am excited would be a huge understatement.

When I am having some trouble with one of my ears I find that swallowing while doing a regular Valsalva (pinch and blow) works really well.

Another big mistake people make is going a little too deep without equalizing. Once you go to deep you're already messing stuff up and making it harder to equalize. Going up will undo it to a certain degree, but your ears wont be like if you had dont it right the first time. Its a downward sprial of ear sadness.

If you cant equalize dont force it though.

Heading out with Silent World in Key Largo for a wreck/reef dive in a few minutes. I'll be bringing my gopro and my still camera with me so I hope to come back with some cool photos and footage. I'll be diving the Vandenberg in Key West on Saturday too and snorkeling Christ of the Abyss tomorrow.

Christ of the Abyss should be nicknamed fire coral capital of the keys. Be careful its everywhere. Last time I was there watching people take pictures with the statue was like a fire coral lesson comedy hour.

Also, if you haven't been to pennecamp be prepared for some incredible reefs.

Best mask defog tech is burning the lens with a lighter until its covered in soot and then cleaning off. Same thing ad toothpaste only way more effective.

I have a gopro. With the addition of the dive housing its a really great camera esp the new one. They are much better suited for video then stills. Although the new one is better at both. But IMHO the gopro is the best bang for you buck for underwater photography.

This blows my mind. I'm scared to try it so I'll do it first with a throwaway mask.


Yeah I only did this after the toothpaste thing failed to defog a mask I had. This fixed it right up.

You've gotta be mindful of the silicone and the temp of the glass. But I've never melted a mask and I'm pretty stupid. As you burn the glass the lens will heat up, so make sure you put it under a faucet or something and also switch between lenses and sides of the lens often, and don't ever apply flame directly to the edges, just get close. Keep working it until its black as poo poo, give it a good rubbing with a finger, and then rinse with water. Boom you have a mask that defogs with a tiny bit of spit.


Another defog secret for newbie divers. One of the most important things to a defogged mask is ensuring your face is the temperature of the water. Usually your face heats up on the boat and steams you're mask up. Cool your face down with or in the water before you don your mask and it will be perfect.


Freediving I equalize probably 200-300 times a day upside-down when I dive. I can mostly equalize hands free but I still need to use my hands for the first 10 feet or so. Its def important to equalize soon and often at first. Further passed the point of correct equalization the more trouble you will have equalizing.

When using my hands I don't do a Valsavla Maneuver (pinch and blow) I do whats called a Frenzel Maneuver. It consists of pinching your nose but instead of blowing closing off your throat with air in your mouth and swallowing. Try it out it may work better for you.

The worst part about diving is figuring out diving related things to do when the weather and viz sucks. Just finished this thing up.
