I use AL because I got them cheap. But I would prefer steel, for the simple reason of loosing some lead.

I use both.....

Back gas-- steel (single and doubles)
Deco cylinders-- Al., with the exception of one st72

Both Al. and St. have their own set of goods and bads....much of it boils down to what you the diver likes to dive. The important similarity is that they both hold gas equally as well. :)

If money matters then you get an AL80. They are 1/3rd the price of good steel tanks. I'm sure many people buy aluminum because of the low price.

But steel tanks come in a greater range of sizes and pressure ratings so you can get closer to what you want.

If you dive in a thicker exposure suit you are going to need a bunch of lead but if you tank in "negative" you can use a little less lead.

I prefer steel and if I was to buy a tank now it would be steel. Since I volunteer as a DM at a local shop I dive AL mostly because I can use theres when dive locally.

I currently use both steel and aluminum tanks. But I use my steel tanks much more since I dive dry most of the time.

If you discount cost for a minute...HP steel is the way to go. Just compare the differences in a Faber FX 100 versus an AL80..... the Faber is roughly the same size, weighs less, and takes 5 lbs less lead, while holding more than 20% more gas (more because an Al 80 is not a 80 cubic ft tank.

Retail price between the two is a giant leap, and many people would rather have two aluminum versus one steel. My last two steels cost around $250, with valve and boot. And yes, they were new...

I prefer steel for the benefits already mentioned. Thermo-Pro Valves, convertable between DIN and Yoke, are a nice addition too. The main advantage with aluminum tanks is pricing.

I don't own a tank yet, but before next dive season I want to get a steel 80...its smaller and lighter than an aluminum 80 and I can drop some lead. In my two piece I need 26lbs and my BC only holds 20.

Would suggest you consider the HP steel 100 instead.. for several reasons:

1. There is very little difference in size /weight between the two.

2. Getting an actual 3442 fill at most places is not possible, so you usually have less than the stated capacity. (Fill Express being the exception).

3. There is very little difference in cost.

4. Coming back with extra air is always better than running out.

5. You still get all the weight advantages, and you should be able to get down to the 20lb number (depending on which specific tank)

I've got to AL80 but was curious about steel im a full time college student so it will be awhile before I try out steel

Steel all the way, reasons pretty much covered already

To each its own best purpose.
I like steel for backgas and cave o2
I like AL for doubles in a wetsuit, stages and OW deco bottles. AL also is nice in argon bottles.

The real point is to do a weighting evaluation and decide what works for you. For instance, in a skin, the AL 80 may be the perfect tank.

Remember though, when diving, its always better to have a tank than not to.

You always have a way of keeping things in perspective.:smiley20:

Basis tank life and current prices, over the long run steel seems a little cheaper. It's hard to finance your tanks over the expected lifetime at a reasonable discount rate. If you have the cash, buy steel unless the size/weight/buoyancy characteristics of the aluminum tank works better for you. If you don't have the cash you might have to compromise.
