crowtribe posted:Well, that's just dandy . The doubles on their backs are usually trimix, and their main gas supply. Tec divers obviously ignore NDLs because they are doing decompression diving. The slung bottles are usually their decompression gas, usually 50% and 100% oxygen for their deco stops at whatever depths they do their stops at. I'll let one of our resident tec divers go more in depth about it.

Bishop posted:To be honest you've kinda stumped me. I've been on quite a few tech boats and I don't think I've ever seen a someone planning on going into deco with a single tank. It's always rebreather (with bailout tanks) or doubles. You can buy steel tanks that hold enough gas to throw you into deco but you lose a lot of redundancy. Possibly they are planning on unclipping their stage and trying to fit through some real tight restriction that doubles are too big for. That happens but normally those people aren't planning on entering deco. Diving can be oddly regional at times so maybe some places out there doing deco with a single tank is more common. Couldn't this also be because some dive boats don't allow doubles, so tec divers will just rock a big fat HP steel 130 or something for a deco dive to get around it?

Prince John posted:Is it possible to scuba dive if you've got bad ears? I perforated both my eardrums when younger and find swimming to the bottom of a pool to be painful but I had heard that it's different with scuba diving because you don't hold your breath. Is there any truth to that or am I forever condemned to snorkelling? Maybe. Possibly. You never hold your breath while diving, but you still have to equalize pressure and that is an issue for people with your condition. Next time you go to your general doctor, ask him about it. If you are REALLY curious you've got two options. 1) Go to a dive shop and ask for discover scuba class. It should be like 20-30 bucks and it puts you in a pool with a divemaster and you get to play with scuba gear. It should give you an indication if you can clear your ears or not. 2) After the discover class, if it is an issue, go see a dedicated ear nose throat doctor, preferably one who specializes in dive medicine. You can contact DAN (super awesome international scuba medical group) for a list of dive doctors in your area here http://www.diversalertnetwork.org/medical/network/physician. I've seen some people walk out of an ENT with the go ahead to dive, i've seen some get sinus surgery so they can dive. People with ear issues vary so much there is no concrete answer any one of us can give you except "go to a doctor".

I'd be very careful with diving between dental work. I don't know the specific dental work obviously, so this may be way offbase, but if it involves drilling/any sort of serious work, diving may not be the safest thing to do. I would strongly recommend asking a doctor/dentist before you plan a liveaboard trip between medical procedures.

lemonsaresour posted:I bought a used Marius reg set from my dive shop a few months ago and used it for the first time today. Everything was working smoothly on the surface in the boat, but when I got down to about 15 feet it started making this really awful squeaking/squealing noise with every inhale. It wasn't difficult to pull through and it didn't stop me from completing my dive, but it got really loving annoying by the 30 minute mark. I've had a squeak now and then with the rented regs but it usually sorts itself out. This just never stopped until I got to the surface. I'm going to bring it to my dive shop as soon as I'm back in town, but does anyone know what this could be? When my life support system starts to make noises underwater, its usually a pretty clear signal to thumb the dive there. Its not like its an important part of your safety or anything. The reg definitely needs to be serviced by a professional, and you are lucky it didn't get worse and effect your dive.

They aren't, " less expensive than a gopro but good", they are "bad products 90% of the time". Anyone Ive ever seen buying one for extreme sports has eventually bought a gopro. I'm just sharing this experience and trying to save a diver some cash in the long run. This hobby is crazy expensive as is, trips are expensive, and were arguing over 200 bucks for a camera. Jesus. Instead of a knockoff get an older generation gopro that will still be better than the knockoff. That's my recommendation in the 100 dollar range.

xxEightxx posted:I see, so my guess is that it's probably more for no deco time. Its literally the same as a regular non integrated dive computer in how it operates. When you use x blend of nitrox, you tell the computer x percentage and it uses that algorithm to calculate your bottom time. The same reason you use a computer versus tables, you have on the fly dive computation of your nitrogen levels based on depth that give you more accurate (and more) bottom time/surface interval information.

xxEightxx posted:One last question about integrated computers, does the gas level monitoring affect anything other than the amount of gas left in your tank? If you program your computer for an air dive, and it has it's own algorithms or whatever to calculate bottom time\no deco time, does the amount of air you have\used get thrown into that equation? If the only thing I gain from having an integrated computer is gas level monitoring, I think I can skip that for now until I get more heavily invested into nitrox etc, type dives, since that info will be tracked on something attached to the reg anyways. No. The computer doesn't know any physiological factors of your body to take into consideration the amount of air consumed. It would be cool if it could, but your weight/height/hydration/sex/sobriety/anxiousness ALL play factors (to name but a few). Every body is different. All the air integration does is digitally read the pressure of your tank. You could put andre they giant and bridget the midget with galileos and they'd get the same deco time for an identical dive profile.

The Vikings posted:Any recommendations on mask defog liquid? I apparently have a sweaty face or something cause my mask always fogs up while my buddy who's using the same stuff never gets foggy. Not really. Like brushing your teeth, the mechanical process of cleaning is more important than the chemical. I use spit and all the divers I know do too. A good option is a spray bottle filled with 50% baby shampoo. Tips. The mask lens needs to be dry or else it won't work. If you defog on the surface then spend time on the surface it will fog. It needs to be the last thing you do before you descend. Not defog and slap it on your head for 15 seconds. Defog, don the mask, and then signal for descent. A properly cleaned mask (when new) is needed. Its not the defog liquid, its the procedure in which it's used that affects how well defog works.

eviljelly posted:I've only ever dived in areas where DMs and instructors were a dime a dozen. I'm not sure why you guys want to jump down my throat about this, I was just asking a question because it really baffled me. If you're saying you dive regularly with no DM, no instructor and no one else who is better qualified to rescue a diver than a 'mere' rescue diver, I accept that this is technically possible but I thought it would be exceedingly rare. I'm not trying to jump down your throat, but i do think its important to go diving with as highly trained divers possible. When i lived in austin, i had multiple dive sites i could visit and did not have a divemaster present. My scuba club would go out, and groups of certified (OW and AOW) would go lake diving all the time, with no divemaster present. Two of us were rescue certified and it made me much more comfortable in the water knowing i was trained enough to hopefully deal with an emergency situation correctly. Vacation diving on boat charters? Yeah, theres a divemaster but he may not always be the closest person to an emergency. In cozumel we had 12 divers on the boat, one DM in the water, and a LOT of space between divers. If an emergency hit, I absolutely would have been closer to about half the group than him so i was also glad i was rescue trained (i was a DM at the time too). I think for local divers who dive regularly at various lakes, rivers, quarries, ocean shores, etc there isn't alway a DM or a scheduled dive event so there aren't always professionals around. I had a few hundred dives before i was a DM and maybe 120ish of those were just me and other recreational divers diving by ourselves. Another reason why i love the course is I became much more comfortable in the water. After the course i knew i was as self reliant as i could be recreationally, and that comfort level helped me enjoy the dive more and get better air consumption. That may not be the case for everyone, but it was for me.

I got my PADI open water scuba certificate late last year (in the Puget Sound, which makes me feel pretty hardcore even though it's mostly unjustified) and I'd like to follow up by continuing to dive before I get rusty and die of an embolism from making an idiot mistake. My problem: I recently moved, and I don't know any divers in my area(Portland, Oregon). As I mentioned earlier I'm not eager to die of an idiot mistake and diving alone is like, wow, number one on that list. I didn't follow up immediately after getting my certification but I don't want to fall out of practice and to do that, I need more divers. Are there any nation-wide (I'm an American) scuba clubs for beginners that I might be able to find a local chapter for? Go to your local dive shops and tell them exactly that. Most shops have clubs that do monthly/weekly/whatever dives locally. You can always post here looking for dive buddies (long shot), or try scubaboard. I think they have a personal section to meet other local divers.

Snuba to me is more of a vacation thing to get snorkelers into scuba. Get a brief underwater experience to see what its like. Scuba is definitely much simpler and less hassle, especially as snuba is not financially feasible to 99% of divers to own and operate. I still want to try it sometime though

Its not the depth itself that does damage to the body, its the decompression/recompression from descending/ascending that does damage long term. Commercial divers who daily go into a chamber? They get their bodies wrecked and can't work after a decade or so. Sometimes to the point where they can't dive or even fly because the pressure change will do so much damage to them. That's obviously the extreme danger, nothing even remotely close to recreational diving. For recreational divers, at this point scientifically, it's pretty safe to say scuba diving (within recreational limits) is not dangerous to the human body long term.

I've got a Halcyon p-valve in my drysuit. I kind of love it, but it is sort of annoying at times. If you don't have the hose at the right length for your junk/mobility, it can tug and pull on your junk and that sucks. If i decide not to use it i tuck it down my other pants leg and it disappears. You get used to the catheter condoms fairly easily. If you break out the suit a few times a year, its probably not worth it. If you dive heavily in cold water its loving fantastic.
