First Scuba Tank Purchase

Stopped by the scuba shop today and bought a new steel Faber 80 cubic foot tank. Looked into the brand, and discovered they’re made in Italy, with hundreds of thousands of cylinders made.

Why steel instead of aluminum? Primarily because steel doesn’t change buoyancy as it is depleted of air, like aluminum does. With aluminum, the diver becomes more buoyant as air is used up in the cylinder, making it a little more tricky to achieve consistent buoyancy throughout a dive.

Steel tanks have thinner walls, but are heavier before you get in the water. This doesn’t really affect me, and wasn’t a concern when I was considering steel vs. aluminum.

So now my system is complete. All I need to do is show up for the next beach dive and get it done. As soon as my knee is healed, I’ll be in the water.

Now I just need to find some great stickers to put on the new tank to really make it complete. My name and phone number are probably a good idea as well.
