Review on Samdo Waterproof Digital Tachometer Hourmeter by Andargie Marquez

Revainrating 1 out of 5

Bad electrical

It's more of an hour meter than a rev counter, just jumps from 0 to 50 and that's it. After about an hour of engine running it started. I have this on a pumping V6 4.3 liter Chevy engine. The backlight works well at night. It's really not worth the money.

Pros
  • Gear ratio setting: 2-stroke engine, gear ratio equal to number of cylinders; 4 stroke engine, gear ratio is half number of cylinders
Cons
  • add later
