Sinlge vs double bladder

[madmole]

You might want to try a UK cave diving trick

I dive 2 x 7l 300 bar sidemount steels in a cave, and yes they are very neg. I then often am carrying several stages (also steel, ally tanks would be written off after a 5 hour carry in with several abseils)

We often use polystyrene floats in the cam bands to help offset the negative bouyancy. Thats how I managed 143m with 8 stages

Doesn't mater what you use to offset being that much negative you have a problem. Wings or suit, you are gonna need a lot of redundancy in case something goes pop.

Why do you need such a heavy rig. Mines much lighter and is good for dives to 70-80m with runtimes up to 1.5 hours. Unless your doing longer and deeper

Why not go the rebreather route and save yourself a whole bunch of weight like I did. I dread hefting my twins now, so much bulk, cld air, noise and costly fills. I can do a weekends 70m trimix diving on a 3L $15 fill

Mike,
Once you get a rebreather AND get confortable on it you will never go back... I cringe at the though of even loading a set of doubles again..

I hear all this shi* about how long it takes to set up... fact is when everyone is trying to get their gear set up between dives I'm relaxing in the sun.. A few minutes before Its time to get in, I suit up and do my pre breathe....

I am doing longest bottom time than I have ever done (On average) with the shortest required decos... I've lost track of how many 3hour dives I have done.....

And its cheap... I get a few days of trimix dives on a single diluent fill, no more lugging multiple sets of doubles and spending a fortune on gas.

I use a double bladder and have no problems with it in terms of inflation or streamlining. I use a Zeagle tech with the big bertha bladder system (yes and a back plate). I tuck the extra inflator hose back out of the way but it's easily accessable. I have practised using each bladder separatly and in conjunction with each other. Train your mind and keep things simple and your skills will get you through. I also dive with a drysuit which depending on my area of environmental choice becomes a third inflation system if required. Face it guys you have a choice to live or die. Train well and you live - let the big guy upstairs decide when your time is up.
