Tank size

[DOXA]

I usually dive with a SS 12 litres. Next month I need some more air, so i think I'm going to use a SS 15 litres. (I know double 12's are preferred, but I don't have the equipement yet.) Do I need more, the same or less weight with this bigger tank?

D.,,, what does SS stand for (steel-stainless steel-???)

The best way to handle your wt. question is to do a simple in water wt. test and go from there.

There should be a listing somewhere that will give you an idea. Below is one site with info on many tanks (in imperial units). I don't know of a metric listing.

There's nothing wrong with a 15 litre tank. You'll probably be able to drop 2kg.

SS = Stainless Steel.

And you are right, except in this case I don't get the tank before the boattrip, so I looking for an indication what to do with my weight.

Thnx, this is the answer I'm looking for!

It depends on the cylinders I'm afraid.

Who makes your twelve, and who makes the 15 you are getting?

Eurocylinders tend to be heavier than Fabers for a given size.

Here are some numbers as a guide (UK standard cylinders - weights do not include valves, buoyancy in saltwater)

Size Weight Buoyancy (Full) Buoyancy (Empty)

Faber 12 13kg -2kg 1.3kg
Faber 12 (dumpy) 13.8kg -2.7kg 0.6kg
Faber 15 16.4kg -2.9kg 1.2kg

ECS 12 13kg -2.1kg 1.1kg
ECS 12 (dumpy) 15kg -3.9kg -0.6kg
ECS 15 18.8kg -5kg -0.8kg

(Buoyancy characteristics from UK Scuba)

Edit: I can't get the table to lay out properly, sorry)

Does anyone have the weights of the e series tanks from pst. I am really looking for the full weights. If anyone can help me, i would appreciate it.

The worthingtons are (apparently) identical:

(full weights are available at the cost of doing some math )
