Is the water pressure exerted on the diver in these caves inclusive of the pressure depth of the sinkhole, or is it limited by the enclosed nature of the caves? While we are on cave videos. I love this one. This cave is on my bucket list. http://vimeo.com/37042655 Bishop fucked around with this message at 22:49 on Apr 3, 2012 |

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. IM FROM THE FUTURE fucked around with this message at 00:13 on Apr 4, 2012 |

So I'm finally getting contacts in a few weeks. Any special precautions I should take diving in them outside of being more careful to not get them wet?

dunno crunk they shouldn't be a problem? I know quite a few who dive with contacts and they always just work fine. They say to close your eyes if your going to do mask flood/clear.

If you're new to contacts, be sure to give yourself some time to get used to them before diving with them. Your eyes will already be sensitive and the additional stresses of diving won't help matters.

I dive with contacts and it's never been a problem. The only obvious advice I can give is to make sure you bring an extra pair of fresh ones with you when you dive, as well as a case and some solution.

Well dude, welcome to being awesome. Diving aside, contacts are so loving cool. I wore contacts and glasses for most of my life, and contacts were such an upgrade from glasses. Well done mate. My only tip is to not be a pussy about using that saline solution, particularly for the first few weeks. Your eyes will be dryer than normal, and loving around with it instead of putting the juice in your eyes is just stupid.

Your eyes will be dryer than normal, and loving around with it instead of putting the juice in your eyes is just stupid. I tried em out when i was 12 (11 years ago) when i was a really active. I have bad astigmatism, so i need toric lenses (weighted at the bottom so they don't rotate as much). When i tried them they were pretty new for astigmatism, really expensive, and not comfortable. Since i was so active, and they were such a pain in the rear end i got really turned off on them until recently where i realize that 11 years is a lot of advancement and worth it to try them again. In diving, i really never had an issue with my vision because i never really dive in water with vis better than 8 feet on a good day. I'm hoping the 2nd trip around, being a not retarded kid and newer contacts, will be the permanent solution. I'm glad there aren't any specific (besides flooding/getting them wet) issues diving with contacts. I can't tell you guys how awesome it will be to actually understand what students are signalling from the other side of the pool. Ladies though. 99% of the reason for contacts. The whole seeing when diving thing is just a perk.

Laser eye surgery is the way to go if you can afford to drop the cash, though the 3-4 months until you can dive again might be a drawback (I had it done in August 2010 and ended up doing my OW in November so it worked out very nicely). Also SlicerDicer great pics. Where were these taken?

There's a growing number of recreational rebreathers out there - the Poseidon Discovery VI and Hollis Explorer spring to mind but I know there are more, and apparently they're set to be the "next big thing." The gas is no weirder than recreational nitrox and the units aren't designed to exceed the 40-ish metre recreational limit.

I make no mistake about how they can kill you and are devices that require utmost respect and care.. Assembly and repair...

I dive at least once a week on my unit if not more and I know that its not a matter of if but when.. It will try to kill me.. and it will do it again... Most definitely. They are pretty serious pieces of gear and should be treated as such. I'm not familiar with any kind of rebreather training (a discover rebreather course doesn't count!), though with a small amount of open circuit technical training I know what that's like and it's very, very thorough. I imagine that recreational rebreather training cover the critical components of rebreather use and maintenance just the same as a technical rebreather course. However, since it's not designed to be used outside recreational limits it won't cover anything to do with decompression or anything involving advanced nitrox or whatever. So long as the operator is taught how to use the thing properly, it shouldn't matter that they're not qualified for deco or crazy nitrox because they won't be using it for that type of diving anyway. Of course, then there's the whole additional prior training that a technical rebreather diver would have, and the (generally) greater competence at dealing with problems, stress management, and the different mindset that comes with tech diving. I'm not sure how much of an issue it would be for a recreational diver without those foundations to deal with catastrophes without freaking out. Depends on the diver, I guess. Interestingly, all the recreational units I've seen or read about seem to be becoming more and more automated. Electronic, automatic, self-checking, plug-and-play sorb canisters, and a huge amount of electronics to try to ensure the operator won't kill themselves. Most of the technical rebreathers operate on the principle that the operator well trained is is capable of second guessing the electronics, and should. There's nearly always some kind of manual override, unlike the recreational systems.

Finch! posted:Most definitely. They are pretty serious pieces of gear and should be treated as such. Well I mean the recreational rebreather works on same concept. There is maximum degree of responsibility with rebreather. Making it idiot proof is all but impossible, for instance you can NEVER fail to close your DSV.. Recreational limits or not what happens if your at 100ft your solenoid fails your at 0.40 PPO2? Diver panics.. OMGADS!!! MY REBREATHER IS NOT WORKING!! If they panic and dart for surface... Forgetting to bail off in panic.. At 86ft they start to go hypoxic.. Just a simple example really of partial pressures. This is a severe problem with rebreathers is that they do not work the same way as open circuit that its always breathable at the surface. Hence why you can breathe yourself to death. http://www.youtube.com/watch?v=WTNX6mr753w Then you can delve into Hypercapnia.. http://www.youtube.com/watch?v=RBtdI1qF11M What about flooded loop? Are they going to spend the time needed to verify positive and negative pressure checks? Keep eye on mushroom valves? http://www.rebreatherworld.com/megalodon-rebreather/39039-always-check-your-mushroom-valves.html What about the oxygen clean? How are people going to treat this and keep from having a O2 fire? Are people really going to be this careful with the gear? http://www.rebreatherworld.com/rebreather-accidents-incidents/123-boat-burnt-down-o2-fire-caused.html This is not kids poo poo.. This is grown up serious business, Then read through the fatality database.. I am new to rebreathers but I respect the poo poo out of them. I read what people did and why things happen I have huge amounts of literature and keep reading. So now to the electronic world. Mine is a eCCR it fully automated in the sense it holds my PPO2 where its suposto be but if it fails I have redundant computers I also have redundant ways of adding dil and O2, I even carry excessive gas to have offboard O2 and Dil most times that also backs up as bailout and deco gas. I do not see the recreational rebreathers as being a safe thing and I hope that people do not get killed and then say that they are any more dangerous than what they are. People dive with brains turned off on OC I see it all the time.. Scary stuff man. I will note that this rebreather is very popular and useable I just question the thought of labeling recreational and treating it as a toy.

No underwater breathing equipment is made up of toys, open circuit or closed circuit. Rebreathers obviously require more training and attention, but it's quite possible to kill or injure yourself with open circuit gear. Many people have. As much as people like to break things up into "recreational" and "technical" diving, most technical divers do it for recreation. It's a hobby, even if it is a hobby where inattention or neglect can kill you (which is hardly unique to tech diving). If recreational scuba equipment falls under your definition of toys, then so do things like sport motorcycles or hang gliders, right? In that case, the rebreather is absolutely a toy.

Rebreathers obviously require more training and attention, but it's quite possible to kill or injure yourself with open circuit gear. Many people have. What he's saying is that a rebreather, even when considered and made for recreational diving, is still an incredibly advanced piece of equipment and needs to be treated as such. With your normal recreational gear, you can just keep your regs/bcd in a closet for 6 months, pick up a rental tank and enjoy an afternoon underwater with minimal effort. With a rebreather, you need a LOT of careful maintenance, and a LOT of specialized knowledge/training to use that equipment, even for a recreational setting. If people see a rebreather marketed for "recreational depths", they might get the idea of "not dangerous" since its not technical rated. Have you ever not really planned a dive because "oh, its only 30 feet. What could possibly go wrong?" In open circuit that probably won't kill you. That poo poo will 100% not fly with a rebreather. You can't go on autopilot, you can't just not plan a dive. You have to be constantly vigilant with that piece of equipment. If people think they are recreational, they might not be and thats where it could get dangerous. Crunkjuice fucked around with this message at 18:35 on Apr 10, 2012 |

It takes me some 2 hours of prep to put my camera, rebreather, bailout bottles, check all gear.. etc. And you cant miss steps.. or you flood something horrible and well at least I have insurance on my gear.. but that does not help if you die right?

Not really any big trips per se, but I mentioned before that I'm heading to the Keys around Aug 2nd-5th. Let me know if you end up being down there around that time. I'd love to head out with you off your boat in Key Largo. This weekend I'm heading down to Jupiter for a two tank dive and in May I'm going over to Venice to do some shark teeth diving. I've also booked a trip to do the Epcot Dive Quest and dive in their big rear end aquarium in August. I booked a whole tour for 12 people with a dive club I'm part of and it ended up about half the cost that way, which is awesome. Oh and hot dropping is pretty awesome. The first time I did it, no one on the boat told me that that is what we were doing, so I hit the water with air in my BCD, looked down and people were already 60 feet down or so. All that charter does are hot drops because they're usually aiming for something specific like a feature in the reef.

I'm on the north side of key largo and about ~20 minutes away from reefs that shops rarely visit because it's too far out of their way. I'm also 45-50 minutes from the artificial wrecks and I can give some pretty cool tours (outside, inside, or both) that stay well within no deco limits. Hell yes. I'll definitely be in touch closer to the date. I have a full set of gear and a pair of AL80s, so I won't need anything to hit the water. Wreck diving would be awesome. I still haven't had a chance to do one yet, though I think we're doing one this weekend.

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. IM FROM THE FUTURE fucked around with this message at 16:20 on Apr 11, 2012 |

I'm going out with the Lockheed Martin Dive Club here in Orlando that I joined last year and they're putting on the dive. I think that the charter is through the Scuba Quest shop in Sarasota, but I'm not 100% positive. The info that was sent out doesn't actually say the name of the charter just the name of the boat which is Conch Quest. The boat leaves out of Nokonis Beach on the north end of Venice. It's a 25-35 foot sand bar area that is supposedly full of the megalodon teeth. The boat captains know of all the hot spots in the area to take you so your odds are really good for coming back with something. I can fill you in with more next month to let you know how it goes.
