If you have two gauges you can compare the difference and as long as you know how far the gauge is off and adjust for it it's not a big deal. The inexpensive gauges are susceptible to accuracy problems if dropped on hard surfaces. The ones in the store have the rubber cover and are pretty accurate and will let you know if there is a big problem or if you have excessive IP creep.antique diver wrote:Unfortunately that's a common problem with inexpensive gauges.

Take one of those IP gauges and give it to a friend. Problem solved the ancient Chinese way...
