Rating: Redundancy = Extra Safety
Reviewer: David Guccione  -  View all my reviews
I and my dive buddy wife both have Sherwood Alum 6cf pony bottles which have become permanent parts of our dive configuration, used on every dive. After 15 years of diving and instructing all over the world, we have come to value the redundancy which a pony bottle gives. She attaches hers alongside her 80cf. I carry mine under my right arm pit on caribinners. We both hang the second stage reg around the neck with surgical tubing. We highly recommend the 6cf pony for the extra safety it brings.

Tough to go wrong with a tank but a visual inspection sticker would have been nice

Questions and Answers for Sherwood 6 Cubic Foot Aluminum Tank:

    All scuba equipment is designed for use by certified scuba divers of any age. It is not designed nor is it safe for use by anybody to use without a scuba certification.

  • mATT:

    how long could i stay under water with the sherwood 6 cubic foot alumanun tank

    Bill  (Certified Scuba Instructor at

    This depends on several factors. The average new diver breathes around 1cu ft per min. So at the surface this tank would last around 6 min. But as you go underwater the air will not last as long. At a depth of 33 ft this time would be cut in half. At a depth of 66ft the surface time would be 1/3, so how fast you breathe and the depth will affect how long the air will last.

  • Johnathan:

    I understand I will not get a full fill. I just dont know how to figure the number of "fills" i would get from this tank. thats my question.

    Bob  (Certified Scuba Instructor at

    Unfortunately we are a scuba company. We do not have information on the number of fills a scuba tank will perform on a paintball cylinder.

  • Johanthan:

    I am looking to buy a scuba tank to for use in paintball...I have a fill station rated to 5000 psi. my question is how many times can I fill my 48ci 3000 psi bottle on this 6cf aluminum tank.

    Bob  (Certified Scuba Instructor at

    This is a 3000psi cylinder, so you'd not get any full fills, technically.

  • cory:

    hi im just getting into scuba diving so im just woundering do you need to get certified to buy/use this size tank I was just thing about using it in a pool with a 8 foot depth I know it sounds stupid but I tried scuba diving once in florida in a pool and I loved but for now I want to just do it in the pool until I can do the ocean training but would be ok to use this in the pool without certification? thank you for your time

    Darrick  (Certified Scuba Instructor at

    Hello Cory, you do not need to be certified to use the tank. But to refill it you need to be a certified diver. Dive shops will not fill a tank to uncertified diver.

TANKS & VALVES: Sherwood Valve

The most used valve in diving. The critical link between your regulator and tank, our patented Sherwood valve was designed specifically to handle today’s high-performance regulators.

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.
