Review on RL HM011A Tachometer Replaceable Snowmobile Waterproof by Anthony Grover

Some disclaimer, I cannot confirm accuracy. This Runleader tachometer was purchased to help diagnose some problems with a Coleman alternator. I haven't narrowed down the problem yet, but the speedo gave some ideas; so worth the money. It's easy to install; Wrap a few wraps around the spark plug wire. This is easy for the operator; Turn on the tachometer and the engine, and then set the tachometer to the correct setting. Easy to read; The display is clear enough to read from close range in most lighting conditions. The results appear to be fairly instantaneous; As the engine speed increases or decreases, the display is updated quickly. For the money and value, I recommend this Runleader digital speedometer.
