The gauges show high pressure(red) coming out of the compressor and low pressure(blue)or vacuum on the suction side of the compressor. When you get a cheap refill kit like you are talking about you are assuming the system is low. If the system is full and your problem is somewhere else you just waste the new freon. Also the gauges are invaluable for checking the system against a leak. A small leak will show up quicker as a vacuum leak than as a pressure leak.
