Steel Vrs Aluminum

[mtyspider]

Well i have used both and once i tried steel tank i got in loved with them

1)For some odd reason the air last longer than with Aluminum in my case.

2)U need lest lead weight's

3)They look cooler!!!!!!!!!!!!

Con's
1)They alway's look scraped and beat up cause they have paint coating they get beat up all the time.

2)I have heard some terrible stories that got rust inside the tank and the air got contaminated.

Aluminum

1)available everywhere
2)rust free
3)Low mantainience

Cons

1)buyoncy is lower

I wonder nobody has ever come to the idea with stainless steel tank's that could be the best idea ever!!!!!!If they exist where i have never seen one.

All your input in this subject is very welcomed i'm not a pro diver i just give my humble opinion according to my xp

Stainless steel is expensive and I believe doesn't have the strength to make a useable tank.

Justus was to make a stainless tank for Dacor in the late 70's/early 80's. It was never delivered. My understading of stainless is that it was too brittle and could not be heat treated to a reliable end result.

Money would cost a LDS a arm and a leg to have Steel rentals,, so its basic economics 101.
if your renting and filling your own the tanks you wont have a rust probblem if you do due deligence on them,,,,,,,

Hey...I resemble that remark.

Gotta stay warm now. I hate to say it but I've even overweighted myself by a couple pounds in order to keep some extra warm toasty air in my suit.

I suppose I resemble that comment to, in that I only dive cold water, but in warm water, with the right steel tank, you don't need much weight at all, which is really nice. Again, bouyancy is key, most aluminum tanks are positive when empty while most steel tanks are neutral to negative when empty. I like a tank with good bouyancy properties, not a floatie.
