Review on 🔧 Timorn Tachometer: Waterproof Hour Meter for Small Engine - Ideal for Chainsaw, ATV, Motorcycle & UTV Engine (Black) by Dale Emmel

Completely inaccurate. At best, it displays the number of revolutions per minute in increments of just 120 revolutions per minute. More often jumps in the hundreds or revolutions per minute range. I bought this based on the advertised accuracy of +/- 10rpm. I would give zero stars if that was an option. I try 2 turns, 3 turns, 4 turns, 5 turns, 6 turns, 7 turns. Nothing has changed. I try all the cylinder fire settings. Nothing has changed. just multiple inaccuracies.
