Overview

  • RPM reading adjustable from 1 spark per 2 revolutions to 8 sparks per revolution. One TINY-TACH™ now works for most gas engines.
  • RPM display from 1 to 19,000.
  • RPM update time 1/2 second.
  • Hour meter records total actual running time on your engine.
  • Job timer can be reset to record run time for record keeping.
  • Coax cable transmits signal without EMF interference.
  • 1 Antenna cable winds around your spark plug wire to give you the RPM reading – clean and simple to attach. Signal strength can be controlled by the antenna wire.
  • Standard cable length is 6 feet. If additional length is required, contact sales for special order.
  • TINY-TACH™ unit is potted to prevent damage from moisture and vibration. Lithium battery life 5+ years, not replaceable.

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.

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.

Q&A

Q: What model of Tiny Tach would work on a Lycoming 235 with magnetos and read accurately?

Part number 10-04182 is a universal unit and can be programmed for your Lycoming engine.

Q: Does this Tiny Tach Model TT2A come with a TSO approval?

No, this unit is not FAA TSO approved

Q: I understand the 10-4182 will work on the Lycoming engines.. will it count off the P-lead connection with proper resistive de-coupling? We don't wish to cut the shield on new plug wires. Is this your best choice for 1- self powered 2- Total tine counting 3- Tach Thank you frank

The manufacturer does not recommend connecting to the P-lead. You must cut back the shield on the plug wires in order for this device to work properly.

Q: Will the Tiny-Tach TT2A work on a Rotax 503 motor?

Yes, it will.

Q: Is the one you sale looks just like this one?

Yes, the photo is representative of the unit for sale.

Q: Is it possible to extend the wire, if yes, what will be the procedure?

This comes standard with a 6 ft lead. Longer leads are available but they are special order. Please contact our sales department for pricing and lead time of a custom length lead on the TT2A.
