Okay since the poor guy who asked a question about depth and time got his thread highjacked, heres the place to continue...
So I pose this question to the masses..
Your at sealevel, your dive plan is 300' for 10 min. Your back gas consists of two 80's with 12/58, you have one 80 with NX32, and another with NX80 all tanks are AL 80's topped off to 3000psi. Your diving with 5 buddies off a boat that has O2 that hang @ 20' you have a slate and lift bags. Your SAC is .4. Are you gonna do the dive?
