Rating: Spare Air pressure gauge
Reviewer: Dennis B.,
Product was shipped and received quickly.
Easy to install.
A bit hard to read gauge with less than perfect eyes.
I think the only time you really need to read gauge is for filling spare air or checking pressure before a dive.

The Spare Air unit has a small piston type of pressure gauge designed into it - but before I dive I like to verify that nothing weird has happened - the piston can be hard to see - - Im a very cautious diver - so the clear visibility provided by this little pressure gauge is very helpful - highly recommended tweak for the Spare Air system.

Rating: Makes seeing pressure a little easier
Reviewer: Peter Z.,
Its better then the pressure indicator that comes with Spare Air but its a hard to read do its size. Other then the size the gauge makes reading the amount of air in your Spare Air a little more accurate.

Rating: Mini Pressure Gauge For Spare Air
Reviewer: Robert Talley, - View all my reviews
The pressure gauge option adds a useful measure of safety by giving the operator an easy numeric psi measure of how much remaining air is available. And, it is no larger than the original stem gauge which provides a very course indication of whether the tank is full or empty. But, being able to tell that the tank is still half full underwater can make a difference when a few extra seconds count. Knowledge is power.

Rating: must have, but hard to read under water without glasses
Reviewer: Wallace K., - View all my reviews
This gauge is an essential part to all divers that use a "spare air" system. The gauge is accurate and fairly hard to read, a magnified or slightly larger gauge would make it perfect. I just dont understand why spare air doesnt make this a standard feature.

Rating: great little gadget
Reviewer: Susan Basler,
This little gadget just adds an extra bit of confidence to using your spare air. While you have a pretty good feeling that you tank if filled when the little button on the pop-out gauge goes out and you hear the air stop flowing, its not the same as seeing full pressure. The gauge shows you how much air you have left, especially useful when just practicing with it in a pool. It really should be a standard on the tank when you buy it.

Rating: good
Reviewer: Nancy Castro,
simple and easy to install...only issue is that the gauge numbers are small. Worth the purchase to see how much air is left.
