Anyone use one of these?

I am still having trouble picking a tank-I am 6'1" and 225lbs to the dimensions of the tank are not too important. I like the steel for weight and capacity but the cost keeps me thinking about the aluminum. I can get two of these for the price of a big steel tank.

Neutrally Buoyant Al 80 Tanks
A little pricey than a neutral 80 but an al100 will give you more air but is about +3lbs empty.
Being a larger person a 100 wouldn't feel all that big.

If cost is a factor forget about the NB80, just buy a standard AL80 and be done with it. If you dive mostly local and want less lead and overall weight compared to the neutral tank then get the HP100. Better tank and less weight, even filled.

The neutral tank is not IMO a good deal.

Thanks for the input...I have some time to figure it out before next season.

the NB80 can be pumped up to 3300 PSI.
longer dives? Is this a consideration?

I believe that you need to fill to that pressure in order to get the same volume of air as in a regular Al80. however, most of the time you will get a short fill.

Yes it is, if you don't get that pressure you won't have a full fill, and based on what I see it's not likely that a person with that tank will have a full fill often. In other words, dive with that tank and you'll have less air most of the time compared to an AL80.

so... stay with the AL80?

[Jaymeany]

I would unless you are going to spring for steel.

on another thread there was a link to cheap steel tanks somewhere.

but i can't find it.
