  • Daniel:

    What is the difference between the Harrison and Sherwood 80 cubic foot tanks if they are both made by Catalina is either one Nitrox ready?

    Bill  (Certified Scuba Instructor at Scuba.com):

    Virtually the same cylinder although the distributors do not list either as nitrox compatible right out of the box.

  • Shannon:

    Do these tanks come hydrostatic ally tested? So all I need to do is put the valve on and fill it with air or EANx?

    Kevin  (Certified Scuba Instructor at Scuba.com):

    Yes, these tanks are hydro-statically tested. After the valve is attached the tank is ready for use.

  • billy:

    I bought 2 tanks and they cam with pro valves shipped loose. What is the torque to install these valves and does any thing need to be put on the threads?

    Arthur  (Certified Scuba Instructor at Scuba.com):

    you just need to give it on solid tap with a mallet. and nothing needs to be put on the treads or the O-ring.

  • Liam:

    Whats the difference between a steel tank and an aluminum tank

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Liam, steel are usually rated at either 3442 psi high pressure and will be a heavier tank so you can take weight off yourself because of the tank weight. Where as the aluminum tanks are rated to 3000 psi and are going to be a lighter tank.

  • scott:

    Hi just wondering can you ship internationally to australia? also on the website with all the tanks it says that valves are included but when you go to checkout valves are charged extra?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Scott, currently we have only 2 silver and gloss in-stock that can ship to you right away. Also the valves do come free with the tank. If you add the tanks into your cart you will see a discount for the amount of the valve.

  • Phil:

    Since this tank is made by Catalina, I assume the major price difference is in the valve (as compared to Sherwood). What is your opinion of the Harrison valve which I have heard is made in China?

    Aaron  (Certified Scuba Instructor at Scuba.com):

    Hi Phil, Harrison makes a good standard valve. We are not sure where they are made at. That would be a question for Sherwood directly.

Aluminum Tanks
Aluminum tanks are cost efficient, long lasting, and readily available, which is why they are easily the most common scuba diving tanks in the world. Lighter than steel tanks, aluminum dive tanks are easier to transport and swim with, giving your shoulders and arms a break on long treks.

Because of their light weight, some aluminum tanks will begin to float at the end of a dive, once the oxygen supply is nearly depleted. To combat this, it's common to counter-weight an aluminum dive tank with approximately 4 pounds. However, 'Compact Neutral' aluminum tanks are made with thicker walls, which increase the weight and help to counteract the positive buoyancy problems at the end of a long dive.
