About Catalina Pony Bottle Tanks, Yellow with Pro Valve

A pony bottle is a smaller tank, which is carried in addition to the main tank. It possesses its own regulator with first and second stage and sometimes a separate pressure gauge. It will is mounted either at ones side or in front of the body or fixed to the main tank. A pony bottle scuba tank is the only true redundant breathing mechanism you can completely rely on.

Depending on the type of diving you plan on doing will determine what capacity the redundant air supply needs to be. Leisure Pro offers five different size bottles to meet every divers requirements. If used for sport diving there are three choices 6, 13 and 19 cu ft cylinders. If deep or deep technical diving or wreck penetration or cave diving there are the 30 and 40 cu ft cylinders available.

The Pro Valve is one of the highest flow cylinder valves available today and is also a convertible valve. Whether you dive Yoke or DIN regulators this valve will work for both. Valve has easily removed 200 bar (3000 psi) DIN insert to convert the valve for use with DIN regulators. Valve has a heavy duty deign with a smooth operating mechanism and multi-ported burst disc plug for added safety.

Aluminum cylinders unlike steel cylinders don't rust, they oxidize. The oxidization of aluminum forms a protective coat that hinders the continuation of corrosion making aluminum cylinders less likely to be condemned due to excessive corrosion. When shipped the tanks valves will be removed and the tank will require re-inspection before being filled. Note: All Catalina cylinders are nitrox ready and meet certificated specifications of the US Department of Transportation (DOT) with DOT-3AL specification and Transport Canada Safety and Security (TC) with TC-3ALM specifications.

good tank bad valve

The valve looks and feels cheap. I ordered two of these, one 30cf and one 13cf and both arrived with damaged/deformed valves.. However the tanks themselves are awesome and you cannot beat the price even with the garbage valve.

Perfect for my needs


from Merced, CA, US

I am a self reliant diver and started to do more deep dives. Picked this up as an extra safety measure. I have used it a couple of times just to make sure and it is perfect for my needs. I purchased the 30cu.


Great tank...


from Caribou, ME, US

This 19cu pony is the cat's meow.. wear it sling across my chest and never is in the way but right there if needed.. And the 19cu is a really good size.. I use the first 1000 psi as a stage and then leave the last 2000 psi as a reserve... Great tank and a great price..


Looks like good quality to me


from Jacksonville, FL, US

Just bought this and only have 4 dives but, seems well made and good quality and durable


buy small


from Port Orford, OR, US

I bought based on dive shop recommendation and the smallest size would work better as a second safety air source. Too large and it adds too much weight if your going off the shore


As advertized


I use this as a redundant air source for Ice and wreck diving.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
sean b  I do small jobs underwater that dont require allot of air
DON S  Recommended to me by a buddy!
PETER M  Redundant air supply for deep or solo dives. Octo is no good if tank is empty!
MARTIN C  Best Price.
LARRY L  I've got a solo card and wanted a pony to carry on every dive.
GEORGE W C  Safety first
MR A  Hi name is Bruno Andujar,I am Scuba Diver. I bought this item because the price and quality is good. I will use for my dive school and shop as well.
DON E  I have one and liked it so I purchased another. Shipping was very fast and product as advertised
WILLIAM M  Needed spare air.
Jim R  This is my second catalina 40 from leisure pro. I'm not sure what most of the complaints are about ? My first pony came with a recent hydro and an excellent quality pro valve... it's only a few months old. oh, and there are no ugly decorative stickers - other than what is required by law ! I'm expecting the second one to be just as nice as the first.
RICHARD M  great for wreck and with students
EDWARD M  I chose it as a pony cylinder for my dive kit. Back mounted on my zeagle ranger with zeagle straps and works great.
ROMUARDO P  What a deal with out the hassle.
ANDREW Z  I use this 13 cu ft. to hang on the back of my sidemount harness to inflate my wing or drysuit
MARC D  Needed a lighter pony tank and LP had the best price.
Shopper  How long will a 6 cu. ft last? (Moderate breathing rate)
ROY T  I doubt the 6 cu. ft. bottle is large enough. How long it lasts depends upon how you breathe and how deep you are. Use your previous experience as a guide. You can calculate your previous SAC if you have logged the size of the bottle, start, stop pressure, and the average depth. I suspect a 6 cu. ft. bottle is likely to last you less than 10 minutes. You will want closer to 20 minutes for a slow ascent and a 15 min safety stop. I think the 19 cu. ft. bottle is the way to go. Remember if you are using the pony bottle, you likely have had a failure of your other system, and you're likely to breathe at the upper end of your typical range.
Chris L  Not really sure. I only use it as a back up, modified rescue air cylinder. I haverified never had to rely on it. Only use it when I have deeper dives.
THOMAS B  Depends what your using it for and what your putting in it. I used it for my rebreather and could use it for hours with oxygen in it. Not sure what other use a tank that small could be used for besides maybe argon for dry suits.
SANDRA O  Have a spare air but haven't used it for 5 years. Obviously needs servicing. Is it serviced the same way as my 63 alum tank?
Frank L  Yes, they still need to have a hydro every five years, and yearly visual inspections.
