Tiny-Tach™
The original gas Tiny-Tach™
An affordable, accurate, self-contained hour/tachometer. Displays RPM while engine is running & total engine time when the engine is off. Unit is waterproof, shock-resistant, has built-in battery that lasts up to 8 yrs. Tiny Tach can be mounted using 2 mounting tabs or double sided tape.
Having a tachometer on board is a very useful thing. It will help the pilot not only to easily tune the carburetor but to monitor the engine in flight as well.

Tiny Tach
Digital Engine Tachometers
TACHOMETER AND HOUR-METER for lawn mowers, garden tractors, jetskis, ultralights, hovercraft, generators, small airboats, and a variety of small engines. Run time feature is excellent for equipment rental agencies.
TINY-TACH can be mounted easily using two mounting tabs or double sided tape. Electrical connections to the engine are easy too-simply attach to the insulated section of the spark plug wire, connect the ground wire to the engine ground. Large 4 digit LCD readout displays rpm while engine is running and total engine run time when the engine is off. Total hours are always displayed at engine shut down, making it very convenient to track preventive maintenance.
Models available for two and four cycle small engines, with either cumulative or resetable displays (resetable by special order). The unit is water and shock resistant and has a built-in battery with a life span of five + years.
Tiny Tach Frequently Asked Questions
- What is the update time? 2.5 sec
- How do you hook it up? You have two wires at the engine, the red wire wraps 4 times around the plug wire and the white wire with a lug to put under a bolt head for ground.
- How is the tach powered? A 3 volt lithium battery is used.
- How long does the battery last? The battery should last 5 years, it is not replaceable, because as it is potted into the case.
- How many models are there? There are 3 main models:
* 1C-looks for 2 pulses/rev
* 2C-looks for 1 pulse/rev
* 4C- looks for 1 pulse/2rev - Will the Tiny Tach work on multi-cylinder engines? Yes, in most cases. Sometimes a filter is needed to cut out electronic noise from the other cylinders. We call this an X and it can be used on all three models.
- Do you make a reset model for resetting the hours? Yes, it is called an R, instead of an NR. So if you wanted a 2C that is resetable, you would order a 2CR and if you wanted a filter it would be a 2CRX. (Special order only)
8. Why does my 2C tach read double on my two cylinder engine? It can be one of two reasons, It can be picking up the other cylinder signal or your engine fires each plug 2 times/rev. NOTE: Some single cylinder engines do this also.
* POLARIS & ARTIC CAT cylinders fire 3x---no Tiny-Tach for them.
* Briggs & Stratton engines use a 2C model
The TINY-TACH will be replaced under warranty by the manufacturer for one year from the time of purchase by the end user. The warranty does not cover failure due to external damage to the tach or wires which will cause it to short. Wires must be kept away from very hot surfaces.
