Doubles and a Wetsuit in the NE

[Danny D]

Ok, usually dive single steel 100's or double 72s in the NE while wet, a drysuit is out of the picture. Want to make a larger set of doubles so that we are only bringing one set-up to the shore or boat. All dives are less than 100', 50 average. Don't want double AL 80's

...With that being said what is the largest set of steel doubles and a wetsuit I can safely do? Double 85's (pumped), 100's what?

Not looking to be bashed by the dark army. Civil chatter...

what can you swim up in case of a wing failure?

I know some folks that double up AL100s specifically because they prefer to dive wet.

Like rivers said, how much are you able to swim up in case of a failed wing? I know some people that dive Faber 85's but I myself wouldn't dive anything but al80's wet. If you need more gas you can always take a stage.

AL80 dubs is all Ill dive wet. If I need more gas I add a stage or go steel dubs with a drysuit.

Al100's have virtually the same buoyancy characteristics as the 80's.....that being said I prefer 120's for doubles because most of my dives on doubles are deeper/longer than usual.

Yeah the double 72s just dont have enough juice for 2 dives . I simply hate the Alums because of their weight characteristics and the amount of lead you have to wear. So you guys are even thinking the Faber 85s would be too heavy?

IN HINDSIGHT I can say that i foolishly once did double 85/s pumped in a wet suit and blew a wing. was not pretty. that dive i did not have a lift bag on me either. lesson learned. went 20+ heavy quickly. That dive made a great argument for double bladder wings or no doubles with out dry suit. The latter being the best alternative.

Are the AL100's you are using the 3300 PSI fill pressure ones?

Go through the calcs for the worst case scenario which is the start of the dive at depth with no BCD lift and zero buoyancy from your wetsuit. LP85 gas alone will be -12, plus another -8 for the bands, manifold, BP, regs. So jump into a pool and see if you can swim a 20 lbs weight belt up from the bottom.
