to read how much air left in tank-one gauge only, any chance out there sell digital pressure gauge/ spg or have to be analog? mostly i found are analog, will in future more of digital than analog? i would assume the digital are easy to read for accurate number better than analog and can turn light on than using glow part. i am thinking to have just one gauge and watch for other things which is good enough for beginner? thanks in advance....
 
Just cause some thing is digital does not mean it is more accurate than an analog. UWATEC made a stand alone digital gauge sometime ago. I am not sure they make it any more. If you want a stand alone pressure gauge just get an analog gauge that you find easy to read. Most will glow in the dark.
