Why does how deep you go make any difference in your wing selection?? Not trying to start something just wondering what your thought process is on this question... BTW: I dive my 55# wing both wet and dry depending on what I'm doing. If I'm cave diving with one or fewer stages I wear it...

Hey DS, I know a couple of people that have taken the GUE cave classes and said they were great! One took GUE Cave 1 from David Rhea and the other Cave 2 with Tyler Moon. I gathered from them that the Cave 1 class was roughly equivalent to Cavern and Intro (no jumps, 1/6 of doubles)...

LOL! DS I didn't think you were the "DIR" type... what're you doing hanging around GUE instructors? :D

What kind of reel are you using for your safety? Just curious. I had an interesting conversation with Deb Green (Larry Green's wife) about spools vs reels... she said they preferred reels for the "safety" because in several of the recovery's they have done a dropped reel or spool was a...

I use spools for Safety, and jump and gap. I use a reel as a primary from open water to the mainline. I mainly use spools because of their simplicity and lack of jamming problems. They do have a few downfalls of their own though. They are easier to drop (haven't dropped one yet but you...

Yeah, just make sure they don't have a fast inflator (they might) or a really long hose (they might)... or a pull dump... or balls on the dumps.. also check under the zipper for something to protect the bladder from the zipper (like innertube).. Not saying the OMS wings are bad just pointing...

Well, I don't know... that's why I said "I've been told"... because I don't know the source of the information... though I've heard it on numerous occasions from different people (not just dir). I've also never heard of a steel tank blowing up because of overfilling unless it had other problems...

Stages are good!!! The hardest part is getting good at picking them up and putting them down quickly and efficiently without your light flailing about.... hint... clip your light off and tuck the cord (make sure it's under the long hose) before you start messing with unclipping the stage.. also...

Basically the burst disk is an unnecessary failure point. They are weakend on every fill and use by flexing... they will eventually blow with even a normal fill... You eliminate that failure point by using a shim that won't flex and eventually blow. Does this happen often? no... Does it...

Yep, wrecks are especially dangerous as the rusting metal will quickly eat up all the Oxygen in the space... Mines, sumps, and any other confined air space should always be approached with extreme caution. I've heard from many people that you can pass out in less than 20 seconds from very low...

Not for Halcyon... most mfg's dream of having a product with such demand that they can't produce them fast enough!! :D You diving this weekend James? DSAO!!

LOL!! Nice analogy UP! :D

I made the same mistake but yes it was a sad situation. 4% O2 doesn't sustain life very long. Good reminder not to breathe air in air domes or sumps.... come to think of it that guy who got lost in the bat cave near Marianna was very lucky the air pocket he found wasn't bad.... that guy was just...

Do you drill on the normal emerg. procedures (other than the S-drill) even after your Full cave class is over?? How often? Every dive? Every other dive? Once a weekend? How about those of you who only dive once every few months? Do you do some drills when you first dive again? I think...

Nope, you fill through one valve and as long as the isolator is OPEN the gas mixes just fine. There's no way more O2 (or He, or air) will go in one tank than the other just because you're filling from one valve or the other. It seeks equalibrium and very quickly. You'll never find anyone who...

Hey Roak, You ever think of going with the AL BP with those 104's? You certainly don't need any extra weight with them do ya? As far as the wing goes... I've got 104's and with all tanks full, AL Backplate, 2 AL80 stages, TLS 350 drysuit (with minimal gas), Cannister light etc... the 55lb...

hehe... yeah but not EVERYONE makes sure they can reach their valves... :mean: Just pointing out that it could be confusing to introduce another set of valves that are different than the current and not everyone would be aware... heck, I still have seen guys that hook the fill whip up to...

Rick, I don't think you'll ever see what you're talking about simply for the liability issue... Imagine this scenario... You're on a boat getting ready to do the ___ (insert fav deep wreck here)... you've got your doubles on and as you're standing there getting ready to step off the boat...

I'd be VERY happy for FL to still be all swamp! The water quality would be a heck of a lot better. All kidding aside water quality is a B I G issue right now in Florida... several caves that used to be crystal clear are now nearly undivable and the problem isn't getting better.... One...

Funny how the people who don't do the dives want to tell the people who do do the dives the "right" way to do it... then come up with all kinds of crazy schemes why "their way" is better... If you're just trying to argue against "DIR" it's not going to work... evey cave diver I know (DIR or...
