A 40 is more then enough for O2...
On a 40, with a SAC of around .7, to be safe, in the 20 foot range, your breathing around 60psi a minute..Thats about 50 mins of O2 time....I get two dives on the Jode out of that...Mind you, I usualy get my O2 bottle filled to around 2400 to help it ride a little better.... |
