Review on 🔍 Enhanced Engine Compression Tester: Accurate Gauge Gage for Comprehensive Compression Testing - Tool Kit Included by Johnny Wheat

I was in dire need of a compression gauge as my snap-on was waiting for a hose change. It worked well for what's in this price range, but the readings seemed low to me. When I turned the bar sensor back on, it read about 20-25 pounds more. I use the rig professionally and rely on accurate readings. This unit is suitable for general home use where it will tell you if you have a good compression balance between cylinders but are not expecting accurate max readings.
