TA100 Smartach+: Wireless Ignition Analyzer and Tachometer

Who it’s For:

  • Small engine mechanics
  • Vintage motorcycle mechanics

What it Does:

Shows you engine RPM and spark plug peak voltage quickly and easily.

How it Works:

  1. Turn the unit on
  2. Position the sensor near the spark plug wire wire
  3. Read the engine RPM and spark plug peak voltage

Warranty & Support:

Covered by our standard 1-year warranty, and supported for much longer. Replacement parts and accessories are generally available for 10+ years.


        The TA100’s unique and proprietary technology allows the user to perform quick and reliable diagnostics of non-starts, misfires, fouled up or damaged spark plugs and/or spark plug wires, by comparing digital read-outs of the spark plug voltage between cylinders on engines using conventional distributor/ignition coil, DIS (Distributor-less) or waste spark and magneto technologies.

        Simple to use, the TA100 requires no special adapters, cables or a scope and is equipped with a large digital display that shows spark plug voltage, RPM, as well as Min/Max readings in real time.
