Hi peeps,

I'm trying to get my head around gas planning rules when cave diving.

I'm going to use 1/4's during the penetration when on backgas, but I'm going to start taking a stage bottle or two with me, so does that mean using 1/4's too?

I've got twin-12's and soon to get a pair of ally 7's so if doing a fictional dive, i would start the dive on ally 1 - burn a quarter, switch to ally 2 - burn a quarter, finally switch to back gas and burn a quarter, at this point I am at max. pen. so I will then turn around using the same sequence of events.

Am I right cavers?

Cheers,

Safe diving,

ciao for now,

chris
