Runleader Digital Hour Meter Tachometer, Maintenance Reminder, Max RPM Recall, Use for ZTR Lawn Mower Tractor Generator Marine Outboard ATV Jetski Motor Motorcycle Snowmobile and Gas Powered

bought as a replacement for a dead battery unit that lasted many years. Installed and operated just as well as the original.

Works great

This exactly what I needed to set the idle speed on my Vespa. I didn't need a tach that I could mount for continual use, just one that I could use to set the idle speed when tuning the carburetor. I installed mine so that I could just tuck it away in the engine compartment when not needed, although it can be mounted if you wish.It worked better than I hoped for and allowed me to easily set my idle speed using the default setting that this unit uses. I could not be happier with the results so far. Time will tell if it lasts and eventually it will have to be replaced when the battery dies (the battery is internal and not replaceable).The display was easily readable in the garage, not sure how it would be in full sunlight, but for me that is not an issue since I intend to use it only for tune ups.The readout was quite stable and there was no issue with rapidly changing numbers. Very pleased so far!Be sure to get a good ground for the ground wire and it should work fine for you too. I wrapped the red wire 5 times around the spark plug wire and then secured it with electrical tape, which seemed to work well.UPDATE: After 30 hours of use (engine run hours) still working perfectly. I decided to mount it on a hole that was already in the metal frame of the engine compartment so it would be more secure - works perfectly and no chance of it slipping down and hitting the pavement. So glad I purchased this tach. My ear is not good enough to tell the difference between 2000 rpm's and 1,800 so I really needed this.

If your putting it on a lawnmower or tractor I guess this will work great. I needed it for my outboard motor so I had to extend the wires. The wires only come like 4 feet. Once extended I mounted it on my console and it works but no matter what setting I have it on for number of spark per revolutions the rpms seem low. All in all it does what it’s intended to do but I’m not sure how accurate it is.

Worked as advertised

Added this tachometer to my 36 hp pro drive and it works perfect. Great product for the price and quality is good. Exactly what I needed.

Good product but it could use better instructions. The hook ups are a little confusing and im unsure how long it will last. It does hook up to the battery and seems to use an internal battery. There is no way to change the battery so i think this is a disposable unit. Also the programming is a bit tedious. Small buttons and small hard to read selections at the very top of the read out are difficult to see especially in sunlight. Im not sure how well im going to like it but i hope once its programmed it lasts and works well.

Only worked for 8 months and just stopped working for no reason. There is no info on how to do a warranty claim on the product. More junk from China
