Hi all,

I have previously had 72cft aluminiums that have now failed. We have been hiring 95cft tanks from our local dive shop but are keen to dive more regularly, hopefully with VSAG.
I would be interested in members experience and comments on the option of steel vs aluminium, probably for around 95cfm singles. Any comments on brands of tanks?
Regards,

David

David,

It all boils down to persomal choice. I'm still using one steel 72 and one Aluminium 50cu ft "baby". If I was about to buy new tanks I would go for the new 95 steels. they are manageable weight wise, and give good bottom times due to their capacity. In some cases you can get 2 dives off 1 tank-and only pay for one fill!

I have never had a steel tank fail a test, but I have had 2 or 3 Aluminiums pit so badly they failed.

My advice is try a few different sizes and types and see what makes you comfortable. The aluminiums often end up quite buoyant at the end of the dive, when you are quite often trying to perform a safety stop and this can be challenging ( annoying).

Hope this helps.

GRRRRrrr

G'day David,

My preference is to use Faber steel cylinders. I have a 12.2 litre one and a 15 litre one. But I'm still a bit of an air pig.

My partners uses Faber steel 10.5 litre and 12.2 litre cylinders on the same dives.

You can get Faber cylinders locally at good prices from The Scuba Doctor in Rye. There are also some great deals over the Internet from some of the dive stores in Western Australia.

VSAG has a new diver day coming up soon for divers interested in seeing what it's like to dive with VSAG. So maybe you'd like to give that a go.

Best Regards, Lloyd Borrett.

Thanks Guys,

Given my aluminium tanks failed, increasing reluctance to carry extra weight and the need for safety stops I agree that steel 95s look the way to go. The pricing out of WA looks very good so 2nd hand doesn't seem much of an option.

Thanks to both of you for your feedback.

David
