Just ask them if they can breathe water better than you as they are more experienced.

Yeah i don't think he knows the meaning of the word "redundancy". I kinda forced myself to bite back a "now you know why i carry a backup" and keep a straight face.

The friend that got me into diving warned me about the "cowboy" instructors and centres in the region, i think i'm starting to experience some of that as i start to explore new places. I'll just stick to what i've learnt and the advice of people that i know take their diving as serious business.


Edit:
Now that i think about it, it might be that he considered a newbie diver with his own kit and redundancy as maybe a little too independent for his taste. Independence = more self-reliant = less reliant on Mr. DM/Instructor.

Holding my breath and I'm playing for keeps.
I'd love to learn to dive as my dad and uncle are very into it and have all the training qualifications. I've been a bit worried about pressure building up in my ears though. I find I can't clear them at all under water and have them block up at least once a year. This is apparently due to having longer than normal hairs in my ear canals but I'm wondering how this would affect diving.

Would this be a big problem if I went diving or is there any way I can solve the issue?

Hairs in your ear canal as in ones you can touch with your fingers? Those won't affect anything in terms of diving since all the pressure equalization happens in the middle/inner ear and sinuses. If its ear wax that builds up once a year you can just be a bit more proactive about cleaning your ears.

If its actual sinus issues then you'll have to talk to a doctor, preferably an ENT who specializes or has experience in dive medicine. If you call the DAN hotline they can point you in the direction of a doctor with dive medicine experience in your area.

I would first go to a dive shop FIRST and tell them you're interested but have sinus problems you are worried about. If they don't suggest it, then ask for a discover scuba class. Its usually pretty cheap (25-50 bucks) and it puts you in a pool with a divemaster with scuba gear and let you actually swim around. Here you can actually figure out with the DM what your equalization issues are, if you need to go a doctor, and then go from there. This way you won't have to sign up for the OW course just to find out your sinuses are a problem.

The DAN hotline is actually really awesome and exists to field these types of questions. Call the DAN hotline. Get the number tattooed on you if you dive a lot. They call it the "Emergency hotline" but in a real emergency it's 911 or the coast guard and I've heard mutiple stories of people calling them with random dive medicine questions. Also look around here:

We didn't sign up for one of the hammerhead specific safaris, we're just going to take our chances. We're taking the Miami ferry on Friday, diving that afternoon, doing 3 dives Saturday, 2 on Sunday, taking the ferry back to Miami that evening and then flying back Monday.

Living in Louisville means you either go to Derby for free or say gently caress it and fly out and back in on empty planes with reverse Derby traffic flow. You can see which one we chose this year. :)

Asked the thread about going diving in Malaysia recently. Decided to skip Kuala Lumpur altogether and meet my friend who lives there in Kota Kinabalu, since he's never been there and wants to check it out. This puts us very close to Sipadan, so that's our plan.

To the guy who went there and posted about it upthread: could you tell me where you stayed (I think you said it was in Semporna) and which operation you went with for the diving? Would you recommend your hotel and/or the dive operation, or would you try something else if given another chance? My friend and I are near 30 and are not rich at the moment, but I'll be making a good bit of money starting in the fall.

On a side note, if anyone has done anything interesting in Kota Kinabalu itself I'd be interested to hear it.

That was me! I went with my girlfriend last December to early January. We booked everything through Scuba Junkies, which operates out of Semporna but also owns a resort on the nearby island of Mabul. The dive operation seemed just fine to me. The boats I think were limited to 8 divers, one DM, and one instructor.

Scuba Junkies has a hotel in Semporna, which is about a 1 to 1.5 hour car ride from Tawau airport. It's nothing fancy, but it was clean and fairly cheap. There was a restaurant downstairs for convenience. There are also other venues along that main street, along with a small department store. I believe there were other dive operators in the immediate area as well, but I don't know about their quality. There wasn't much to do in the evening except sit at the bar and have a few beers; that was fine by me as 3 dives in a day wipes me out (no nitrox) and I was snoozing by about 9:00.

We stayed in Semporna for a few nights, then moved to Mabul and stayed in the resort for a couple. The resort was very nice, it was next to the docks and had some good food and facilities. Rooms were more than adequate. There is a small village on Mabul you could walk to as well. There's also a very large "sea gypsy" (as everyone called 'em) community next to the resort. 'Twas a thin line between heaven and hell; I don't think I've ever seen poverty worse, except maybe Cambodia. It made me feel pretty guilty and I had some conflicting emotions over the whole disparity, but I won't bore you with that aspect of it. All that poverty brings a lot of trash with it as well. The sea floor is at times covered in refuse. Usually when I dive I'll pick up the odd can or plastic trash here and there, but in Malaysia I soon gave up entirely.

The dives around Mabul and Semporna were good for the most part. There was a lot of macro level creatures to take in. Visibility wasn't the best I've seen, but it was perfectly acceptable. You'll see a lot of neat nudibranchs if/when you go.

Sipidan was clearer and had stronger currents. The coral was gorgeous and you could seem some larger fish (and tons of turtles). If I were to do it all again, I'd spend more time at Mabul (or Kapalai island, 10 mins away, also with resorts), rather than Semporna.

Or, you can just go to Palau. :P

(I swear I'll post pics. Really really.)

Oh, as for KK things to do - I stayed there as a book end to my Sipidan trip. We went on a river cruise to see Proboscis monkeys. It was...ok.

The Malaysia pics I already posted, my new Palau pics have not been.

As for staying at the resorts, I think it's a good idea. You'll be diving at least three tanks a day, four for Sipadan. The only problem is you may get bored in the evenings, as entertainment options are limited. There is a length of beach you can use however. There's also the company of other divers too.

If you're like me though you'll probably be wiped from the day, load up on dinner, then pass out in a limp fever of fish and fins.

Btw, there's no house reef and therefore no unlimited house reef diving, which is a bummer. I implore you to do a night dive if you can, I didn't and regret it.

The thing is, it's a bitch to clear them if you are talking about in a pool with a breath of air in your lungs.

It's so much easier when you can take your time and breath to do it.

I thought you guys might appreciate a "I did a dumb thing" post.

Went camping up near Tobermorry, Ontario, right about the end of October. Brought our cheap 3/4ths wetsuits and figured we might give swimming a try (Crazy locals swim in just bathing suits until ice forms). Also picked up a hood, gloves, and boots that were on sale at a local dive shop. In talking with them, they informed me that with that much neoprene on me, its best to have scuba gear and weights due to buoyancy.

Went down to the Grotto there, where you have a sheltered cave with a pool of water that has two tunnel connections to the bay. I've always wanted to swim through it as you can see a lot if light from the other side. Turns out my slightly over sized flippers now fit snugly with the boots on, so I went for it. Halfway along I realized this was a bit longer to the other side than I expected, but I could have gone another 30% further if I had too.

Now as possibly dumb as that was, I have to point out the really dumb parts. 1.) I didn't expressly tell my friends I was going to do this, so essentially they see me dive down, then not come back. 2.) It was rather windy and over cast outside.

So I come up, and realize oh poo poo, this was kinda dumb. I'm treading water in 3-4 foot waves, about 10 feet from a nearly vertical cliff face. I'm stuck between watching the incoming waves so I can keep my head above water, or the cliff so I don't get slammed into them. I'm also feeling slightly choked by the hood, and along with fighting the waves, I'm not really getting my breath back.

I made one attempt to dive back down, and now was noticing the boyancy as my flippers flailed in the air. I also noticed that the cave going back was more of a black void in the rock than a nice greenish glow from the other side. Back to treading water, I hold back some mounting panic, and consider my options. I could swim up or down the cliff to where I could climb up, however those had nice crashing waves, and lots of fallen boulders and rocks to be knocked/wedged into. Or just aim for the black void and hope for the best. About this time, I don't quite get over a wave, and catch a mouth full of water. Thankfully I swallowed instead of choking on it, and decided gently caress this, I'm out.

Made a second attempt, got my flippers in action this time, and aimed for the center of the black void in the cliff. Already feeling exhausted, and thoughts of what will happen if I don't make it, I start to see a faint glow ahead of me. I aimed for it, and with maybe another 5-10 seconds of breath left, I surfaced.

My friends were pissed because I was gone for about 5 minutes, and had no idea if I was ok or not. I just hauled myself out of the water and sat down while my nerves settled, and contemplated what a dangerous position I just put myself in.

Suffice to say I have a lot more respect for cave divers, and don't think I'll ever get into it myself. Recreational still looks fun though.

Also here is a video of someone free diving the same spot. Starts from outside and heads in, complete with the pitch black view. I doubt I'd ever try that second path.

ha I did the grotto free dive last year for labour day weekend. Water was freezing then, I couldn't imagine how it'd be at the end of October. I was going to bring my scuba gear but gently caress hauling it 2kms from the car.

When I did the swim through I was all decked out in my hooded vest, snorkel, mask, and freedive fins and cruising through the tunnel...surrounded by locals sprinting through with nothing but shorts. :stare:

Could you have also just swam around back to the grotto entrance or were waves crashing into there too? It's not a far swim especially with flippers on. Glad you made it out okay, but I agree that it was retarded that you:
1. didn't tell your friends. The Yogi on duty told me a lot of people misjudge the clearance and smack their head just before surfacing leading to concussions and stitches.
2. didn't check the conditions (on the open side). You knew it was windy. A quick peek from the cove could help.
3. didn't have a backup plan. possible to swim to the cove to the North (closer) or South (further)

Apologies if I sound holier than thou, but I think it's a good example for new divers reading this thread to show how a simple swim through tunnel can have problems if the risks are not managed accordingly. Thanks for sharing.

I'm a warm water wuss, but I'm hoping to check out five fathoms park for the first time as well during labour day weekend. If you're up there, definitely check out the grotto with your mask and fins. Free diving the area was super fun - the flat step rock contour is an amazing scenery especially when it's +75ft visibility.

I call them fins, as it's easier to say, but if someone says flippers I know what they are talking about, and you know it too. The word is an accepted synonym for fins, isn't it?

It's because they're being pedantic stereotypical know-it-all nazi divers. Saying flippers, blades, or fins is standard nomenclature used interchangeably for anyone who grew up competitive swimming and lifeguarding doing water sports.

Dive fins are specific for diving. Golluk could very well have been using swimming flippers (he didn't indicate).


edit: VVV whatever. Sure let's be pedantic. First, Golluk wasn't scuba diving so we're not discussing scuba diving.

Second, it's not JUST a beginner thing to call them flippers but EVERY OTHER water sports in which you hear those terms. Many divers enjoy a whole array of water activities, hence, why they use different terms than you. Maybe it's even cultural - my aussie friend still calls them flippers after 8 years of diving.

Third, if you think nomenclature that minute equates to meriting an extra eye, then you're doing it wrong (maybe just ask them how many dives they have???). But sure, go for it, what do I care how you spend your time under water.

Just like how it's okay to order online from leisurepro, who gives a loving poo poo if they call them flippers, fins, blades, or paddles, etc... as long as you understand what they're talking about? Why be THAT guy??? VVV

All things considered, its just a beginner thing to call them flippers. Lets be honest, how many divers actually call them flippers? Its just not correct. When someone calls them flippers, its a great indicator to let me know that they are probably a beginner and might merit an extra eye. As for competitive swimming/lifeguarding, i'm sure thats fine in those hobbies but we're discussing scuba diving.

Yeah but I know a guy who dives a re-resuscitator unit and he uses pure O2 all the time. He has like 50 dives so I know he knows what he is doing.

(As a serious side note, it's worth pointing out that Navy O2 rebreather guys used to dive to 60 ft/18m on their O2 rebreathers. Which I find insane, but then again I have done 2.8 ATA of O2 in a chamber so it's not like it's immediately going to make one seize. Though of course in a chamber one is dry so tox hits only cause bruises not drowning.)

And you probably got air breaks also. And you were not so active like you normally are while diving.

My buddy told me a diver in our group was planning a dive to 70m on air he asked me if I would follow up.
I told him about the oxygen border of 66m and that we would be in deep trouble if we would pass this depth. Actual going deeper then 40m on air is already very dangerous.

We did 4 dives a day on a live-aboard in between sleeping and eating. I skipped some dives because it was a holiday not a seal training.
After some days my buddy could not go back onto the boat anymore he had no strength in his legs anymore.

Also we did do some wreck diving on the Thistlegorm. This is a wreck loaded with 2nd world war equipment.
The average depth is around 25m deepest is like 35m.

We did do 4 dives on it.

On one of this dives I had 60 bars left and 1 minute left before I would go into deco.
So I signaled my buddy I would go up and leave. We were with 3 divers. He would stay for a bit he signaled me back.
So I went up did my safety’s and left the water.

Now I had my diving gear of and was enjoying the sun. Then the third diver came out of the water. This was a fairly new diver.
He told me my buddy had 7 minutes of deco left to go and 5 bars of air left.

I was like WTF... I had like 30 bars left in my tank so this was not an option.
So we had a diver suited up again and going back with a full tank.

We did not rush everything in a calm way get they diver suited up. He went in.
The we made sure we had some backup divers if needed. The sea was calm we had enough air. We had lines in the water and no current. We had pure oxygen is needed.

My buddy did his deco left the water. He was laughing his nerves away. He knew he screwed up big time.

Sometimes I feel like I am the last safety for him. I need to tell him he has children and what the limits are etc.
We were once at 35m in deco with the 3th diver with us and suddenly he was without a bcd he wanted to check something he heard bubbles he later told me.
So at 35m in deco we helped him to put his bcd back on.

And you probably got air breaks also. And you were not so active like you normally are while diving.

FWIW, for the original tolerance test, we get no breaks until we start to tox, because it is in fact a tolerance test and a "this is what it is like to run through the ConVENTID" for you and a patient, and a "this is why why hold the mask on with our hands instead of putting the straps around the back of the head" demo.

Everyone's a bit different when it comes to o2 toxcicity, and even individuals vary. I think the 1.4pp02 limit is a bit soft, 1.6 seems more reasonable and I'll break that for a moment if for some reason I NEED to. The Navy has done a ton of research on it. A brief search dosen't pull anything up but I've seen videos of people in Navy chambers slowly having their pp02 raised until they toxxed. They could get significantly past 1.8

"Welcome to the Navy son, your country is proud of you. Now get in this iron tomb and let us give you a seizure for science."

Ha! how did I miss pupdive's post above mine.

Speaking of the poisons of the deep, the dive center where I got my OW cert offers advanced (Nitrox) as well, which I plan on taking. Part of the class is bringing you down to 33-35m, getting you intentionally narc'd and making you do simple arithmetic on a slate, or try to figure out children's toys and document your timing.

I'm excited for this.

That could've gotten in my eye!

I THINK OAKLAND PD'S USE OF EXCESSIVE FORCE WAS JUSTIFIED!

I'll do some variation of that during a deep dive for AOW classes. I have a pvc pipe puzzle that i'll have them assemble, make them do some basic math stuff, or a favorite of mine, have them write a poem or haiku. Anything to get the point across that your cognitive functions slow a bit at depth. The poems are usually pretty interesting.

My haiku for my deep dive of AOW.

gently caress I am cold gently caress.
I am dumb as all hell gently caress
gently caress this. gently caress gently caress gently caress.

I have since learned just because a 3mm suit is fine on the surface, doesn't mean water won't drop 30 degrees at 100 feet :(

NO DUH HUMANS BREATHE OXYGEN

EVERYONE KNOWS THAT

Hostility much? I am just explaining the gas mechanics.. oxygen breathed beyond deco purposes is likely lethal... You know the whole physics and physiology thing :)

LOL... I dont even feel nark ever at 40m or shallower I spend so much time down there I am just acclimated I guess?

I'm sorry, I can't hear you over the sound of how awesome I am.

Oh slicer I was just kidding, we were mocking bad divers that know nothing, like ones that think we breathe oxygen at sea level.
