Benjamin Scuba Yoke, K-Valve

It works. The yoke fit on the scuba tank, the quick release coupling fit on the fill nipple, and the pressure relief valve did not leak.

The pressure gauge is difficult to make out.

It helps if you already know what needs to happen to fill and then release the pressure in the line before disconnect - because it was not clear to me from the printed directions. But with a little experimentation it became clear.

As I held this rock-solid handful of precision-made steel and brass, I saw the "Made in the U.S.A." printed on the body and said worth the extra $$$ for a quality-made tool. Very, very easy to attach to a Scuba Tank. Very quickly fills the cylinder on the gun and releasing the excess gas pressure was easy also.

I would definitely make the hose longer so as to at least allow some flexibility to attach this to the gun.

I waited a long time and spent hours using the hand pump to fill my guns which does give a great workout but which I don't always wish to do. While this costs relatively close to a hand pump, it saves so much time!

I filled my gun in just a few seconds. In fact, it took me less time to fill up my gun than it normally takes for me to start filling up my gun while using the hand pump.

Time is $$$. This saves a lot of time.

Easy hook up.

The gauge is not easy to read.

If you fill your own portable dive tank the pressure gauge is not accurate enough and is too hard to read accurately.

It does what it was designed for. However, this method has its draw backs.why not ship a valve that is designed specifically for the purpose of charging other sources. A unit with a pressure guage and a pressurecheck valve on the incoming side. Real simple.you charge the tank, at 3000 psi it automatically cuts off. Oh and a 24" fill hose.

Compact, easy to place on the scuba tank. Easy to read gauge. The connection to the tank fitting went on and off easily.

Add about another foot of hose.

Remember to read the instructions. Not all work the same.

EASE OF USE

LONGER CONNECTION!! VERY AWKWARD TO USE IF USING A LARGER SCUBA TANK

Does the job nicely.

After the fact I found on line for a lot less money.

Works well ,looks like very little could possibly go wrong,should last a lifetime.

5000 psi gauge could be larger, more easily read.

Short hose minimizes pressure needlessly lost.

Worth every penny not to have to use the hand pump. seconds to fill my discovery.
