i like the idea of having a gauge that clips on to give less hassles.
the main gauge i've been using lately is the one attached to my bicycle pump which is also pretty consitent.
you might want to look into a good bike pump as a solution to both your clip on gauge and a convenient instant adjustment should the pressure be off.
replacing the original gauge with a precise one should also be pretty easy as long as you're sure the set up is a screw on one.
gary's electric pump is also hard to beat trackside i borrow it all the time!
as a habit i also step on each tire before each grid practice or race to check deflection and pressure.
you'd be surprised how many times that habit has saved me un-needed track grief.
the thumb test in the middle of the tire is also great and will give you a heads up on worn out tires when you get a little experience!
on separate stand alone gauges i just use the same crappy gauge each time looking for the same reading side to side.
accurate reading are nice for that but beyond matching pressure side to side i never worry about a particular pressure.
that is because there is no absolute or perfect tire pressure for every track.
tire pressure is personal taste as each driver has different wt factors,driving style,kart engine combo .
add to that heat of day or part of day you're running,humidity, slickness or lack of on a track track layout the list goes on.
it is far more important that the front pair of tires match each other.
the same goes for the rear tires matching each other.
sometimes it's an advantage to run different pressure reading but that is complicated and for all out competition.
being competative with offset tire pressures is more about razors edge racing and we aren't really racing though some may disagree.
Good even tire pressure is more important because that's about safety and a consistent performance on the corners.
So , imho , what you want to aim for is a consistent "feel" with your tire pressures.
a consistent tire "feel" allows you to run on the track right side up and not practice cutting grass!!
anyway even with a crappy gauge , with a little experience you'll be able to keep your tires at a reading that is workable trackside at each event.
