NOTE: Some engines, such as multi-cylinder outboards generate considerable electronic "noise" and may require a light filter to assure a clear RPM reading. You will find a "comments" section at the end of the order page where you can tell us about your engine – what kind and how many cylinders it has – so that we can make any necessary adjustments.
One year warranty
Note: This will not work with a shielded ignition harness or lead.
Worked very well- fast shipping. Wound highly recommend to others Thanks R. B.
Replacement for my old Tiny Tach. Battery finally gave out. 5 yrs old.
The battery in my first Tiny Tach lasted from 1998 until 2015. Results may vary.
My Tiny Tach on my Starflight Ultralight with a Rotax 377 just died due to battery failure. It has been on the craft for about 20 years and until today was working great. I am disappointed that the battery is not replaceable (anyone know a hack?) but otherwise have been very happy with it and will replace it with the same.
My tach has been in service for 4 years now and its still working well. I have a Lyc TIO540AF1B. We did have to cut a small opening in the shielding and then wound 10 turns over that opening (instructions recommended 3). It hasnt missed a beat since. Beats an optical tach as they dont work at night.
If you are building an experimental and would like to use this device, DO NOT buy it until the last days of your build. The battery only lasts 5 years and is NOT replaceable. After that, its a Tiny Boat anchor.
