Review: Awesome tachometer for the price - Awesome tachometer for the money. Super simple install - just wrap the one wire around the spark plug wire 5 times. Seems accurate and easy to use. Ruckus is a single cylinder 4 stroke and should have been the 1P2R setting but it read super high. So went back to the stock setting of 1P1R and works great. Really meant to be a tuning tool and not so much a check all the time tool as you can’t see it at night - have to press the button to light it up. Not a big deal but just be aware.
Review: Love these - Bought for a brand new Yamaha SuperJet but doesn’t work because it has coil packs and there’s no way to wrap the wire. Turns out I needed one for our 1989 WaveRunner because the last runleader hour meter got submerged in water for too long. Works great for keeping hours and watching the rpms. The 1989 is carbureted. You have to know the rpms to adjust the carb. I have runleader digital tachs on multiple motorcycles. I have one that also has a temp probe for water temp on a BMW motorcycle.

### ⭐⭐⭐⭐ It works, mostly
*by T***6 on May 14, 2020*

Hey, it's an inexpensive tachometer that fairly accurately records engine speed on small motors. I like the fact that the battery is replaceable (some out there are not and so only good for a few months and then tossed in the trash), it's backlit on your terms (on/off/intermittent). What I would like to see improve is a bit more length in the cable (it barely made it to the sparkplug wire on my Yamaha golf cart) and a clamp at the end to go around the spark plug wire to pick up the signal. Wrapping the wire around works at about a 90% frequency and accuracy rate. They tell you that fewer or more coils around the wire let you fine tune the rpm readout - nope, makes no difference at least on the single cylinder 4 stroke in my Yamaha. But hey, it's inexpensive so expecting too much is unrealistic.
