About Blue Reef Pony Bottle Tank Small Pressure Gauge PSI/BAR

The Pony Bottle Gauge is a tiny gauge that easily connects to the 7/16" threaded high-pressure port of your pony bottle regulator or other alternate tank regulator to show pressure in an easy-to-read display. Any diver who has used a pony bottle knows the hassle involved with trying to find out how much air is in the tank. Switching regulators to view the primary pressure gauge or adding a separate pressure gauge to the pony bottle is a problem solution. Now with the Pony Bottle Gauge, all those headaches are over. The Pony Bottle Gauge has a pressure range from 0 to 5,000 psi (350 bars) has an easy to read color coded display for at-a-glance pressure check, comes equipped with a high pressure O-ring so it's ready for immediate installation, and is a great accessory for any dive bag.

Handy gauge

Since I have a hoseless integrated computer system, I attached this to a HP port on my regulator to ensure I have a full fill as soon as I open the valve and don't have to wait for the transmission. Quick and easy immediate check.


Most Liked Negative Review



You get what you pay for. This low cost gauge is low quality too. Was inaccurate by 500 psi when tested. Leisurepro was greAt and processed the return right away.

Does the job


from Scranton, PA, US

Compact and seems accurate. Good for pony bottle, especially if you sling it.


Great mini Pressure Guage


from Manchester, NH, US

Great price, easy to read. I bought it to use with a special adapter from another scuba vendor in order to use on my Spareair. These are great for divers using a dive computer with a transmitter; it allows for a quick check of the air pressure.


Excellent Value


from Solomons, MD, US

This pressure gauge is perfect for a pony, it is easy to read and has a low profile. Does not interfere. Easy to be sure that there is not a slow leak while traveling to dive site.




from Sarasota, FL, US

Just as presented, we use them in the second HP port as a backup to the transmitter in the first port.



My girlfriend and I don't like the idea of knowing how much air we have left, to be dependent on a battery. I have a couple older air integrated computers while she uses hoseless. I bought 4 of the these to cover our regulators. All 4 seem accurate and easy to read.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
ROGER B  built 40cf spare air and needed compact tank gage
DAN S  Wanted to see what breathing underwater was like
WILLIAM P  excellent value in a pony gauge
PETER M  Compact pressure gauge for a pony bottle backup air system.
Val P  size was a little larger then the one I had and the old one was fogged up. I like it
Clarence S  These guages have multiple uses. The obvious is on a pony regulator. However, if you have a regulator with a hoseless computer, you can put this guage on a spare HP port so you can make a quick check of your tank pressure without having to power up your computer wrist unit. Also, prefer the larger dial face over the "peanut guage" style of pony guage.
JOHN W  Several were defective and I have returned.
ROBERT R  Good. Thrifty (I'm not cheap). And it worked well until it fell out of the back of my pickup with my pony bottle and emergency reg.
BITHEL KEITH P  Readable and works and the price was right.
RICHARD C  nice good quality gauge.
ANDREW Z  for my 13 cu ft argon bottle along with a high pressur relife valve
MICHAEL R  Good pony tank valve...
Shopper  Are the threads on this Blue Reef pony gage the same as the threads on the Spare-air stick gage? Would this work on Spare-air?
KRZYSZTOF K  Sorry for late response, I was out of the US diving in Indonesia. I love this item , really works , also it should be working on spare-air. Krys
DAVID S  It looks like it will. Same thread as 99.7% of 1st stages out there. I just tried a standard high pressure hose and it fits so I am pretty sure it will.
Shopper  How did everyone tighten this gauge after you hand tighten it? The neck is round so I can't put a wrench on it. The gauge itself is has 6 flat sides similar to the picture but not exact) and it's about 1-1/8 inch wide. I have a ton of wrenches but not that big. Even still I don't have one that size in my save-a-dive kit so if I have issues with it while diving (like some reviewers have) and have to remove it on a boat I won't have the tool for it.
Daniel G  I just used a large crescent wrench. Even a set of channel locks would work. Remember, the actual high pressure seal is made by the O-ring. As long as it won't work itself loose by unscrewing, you don't need to really torque on it.
KEITH C  Between the threads and gauge you will see where you can use a small adjustable to tighten the gauge. I am on a regional public safety dive team and we use these on all our pony bottles. Never had a problem except one broken bezel when a knucklehead smacked it.
T C  It doesn't need to be too tight even though it is high pressure. puvan adjustable wrench on it and give it a half turn
Martin B  I used a large crescent wrench. Just snug down. Barely past hand tight
PAUL N  Kind of surprised you don't have a wrench that big -- a garden-variety adjustable wrench should do the job. BTW, if you don't have one, it should only cost a few bucks and will be worth the investment, as you'll use it for lots of things.
Mark A  I do have an adjustable that will fit but don't want to mar up the finish so I'll wrap it in a rag. I'm also surprised that I have to crank down (conservatively) on the actual gauge to tighten it. So be it.
BRIAN N  You need a small slim crescent wrench. Hard to find but they're out there. It will double as a wrench for all your hose connecting to first and second stages
