Suit inflation.

Hi all,
What is the best way to use a suit inflation system with the meg,ie under a narked at 90 stand or just attached to the can?
Many thanks, Kev

Re: Suit inflation.

I attach mine to the backplate with the Dive Rite argon harness. Works great.

Re: Suit inflation.

I'm very VERY new at this CCR stuff but dive nothing but caves. Lots of up and down.

I tap into my 19cf Dil cylinder for the wing (which is my primary buoyancy device) and I know, right now, I play with it WAY TOO MUCH. I tap into my bailout bottle to take the squeeze off of my drysuit.

My point is, me being VERY new, we all know I will use gas more than anybody else here and so far I do not see a need for an off board cylinder for wing inflation. I own such a system (6cf cyl. w/OPV, blah blah blah) from my Great Lakes diving days, I just don't see the need to bring it along.

I am sure you know by now that ups and downs in caves can blow thru alot of Dil quickly. I trust you are making an allowance for this when you calculate what BO you need for a CCR failure at point of deepest penetration?

Works fine except when you have TMX in your bailout!:;)

Re: Suit inflation.

I have mine bungied into the base of my Narked @ 90 stand and I am pretty happy with it there. Prior I had it mounted on my waist strap & bungied to my backplate, but I found that to be kind of a pain in the ass, particularly with multiple bailout bottles.

Re: Suit inflation.

I find a simple 6 cf bottle attached to my backplate does the job nicely for me. If the dives aren't over 200 ft or so, works for 2 dives before going MT. It is also worthwhile to remember that the dedicated bottle becomes, w/ drysuit, a fully independent backup for your wing buoyancy system.

Of course.

I don't use nearly the amount of gas in my suit as I do my wing, only enough to take some of the bite out of a suit squeeze, but your point is well made. Indeed I figure it in. Realistically how much would that be? 3-4cu/ft :D In the Great Lakes I could make a couple 200+ foot dives with 1 fill in my 6cu/ft argon bottle...I know, it's a square profile.

I suspected you were but thought it worth mentioning if not for your benefit then maybe someone less experience that might be reading. I really can't say how much you should figure in. I guess it depends more on the cave profile your diving and how much you use DS versus wing. Like some other posters I found that a 6cuft bottle would do about 2 square profile wreck dives on the DS.
