Tanks: 80's versus 100's

[Don Burke]

I have the problem where I need lots of weight to get down and then once Im down I have problems with bouyancy and fight that, thus use more air.

Anyway, Ill get it worked out, loose some of the weight and work on breathing technique.

You might be trapping air in your suit and using extra weight to get that under. Try hanging out on the surface at the beginning of the dive for a few minutes to get as much air out of the suit as you can. If you can take a couple of pounds off, it will save you much of the tail chasing with your bouyancy.

Quick warning for those buying AL100 tanks... remember that these are rated 100 at 3300 psi, and most places just toss them on the whips with the AL80 and fill them to the same as the 80's. When that is the case, you are 10% down to begin with, so then that means you're carrying the extra weight of the AL100 for about 10 extra cubic feet... instead of 20.

So just check where you get your fills, and make sure they'll dial in the pressure for those - otherwise, it might not be much of a benefit for you.

GOOD tip, Ill keep that in mind.
