weight of a steel and alum tank.

[bigman241]

Can someone give me the numbers for the given weights of steel alum and nb alum tanks both filled and unfilled. Also. I am perparing to buy all the gear. I plan on getting everything but the tanks then buying two tanks next spring when local diving comes around. I am thinking a steel tank something big properly a 130. Heres my question on that what are the pros and cons of the hp pressure tansk vs the low pressure. If i go highpressure should i buy the din reg setup for my reg then buy the din to yoke adapter. I am leaning toward the highpressure but also want to travel and rent tanks

Scuba Cylinder Specifications from Tech Diving Limited - 928-855-9400 I refer to this one frequently a lot of current cylinders are compared here.

Most first stages are made to take both Din and Yoke fittings, but it is easier to probably get a Din fitting and a yoke converter for when you need one. Some people use the din fitting even on low pressure tanks (depending on the valve that is fitted) as they feel it is more secure, however most hire tanks will be Al with yoke only valves, hence the need to have a converter.

Zeagle regs can be converted between DIN and yoke in under five minutes, including looking for your crescent wrench and Allen wrench.

Be careful you don't confuse weight and buoyancy... most tank specifications give both.

If you go with a high pressure tank, it is a little harder to get good fills. However a high pressure tank can also be a low pressure tank. I dive with LP104's. My 104's should not be a high pressure tank. When I am in the market for new tanks i think i will get the HP130's. They are a lp104 at the 2640 psi and a 130 at the 3442 psi. And i dont have to worry about overfilling them. An aluminum tank will be positive at the end of a dive and will be bottom light.

I take it thats the reason for the neatural boyount al tanks. I planned on al but with the fact i am sure i will need a good amonth of lead. As i flote in the water even if i stand on my head. SO i am leaning toward the steel 130.

bigman241....you'll love steel tanks.
I used to need 18# of lead to sink my naked bouyant @ss when diving AL 80's and 30# of lead when diving 7mm.
I switched to HP 120's and need nothing naked and 4# with wetsuit.
