Early Products that Defined GTC
In 1992, General Technologies Corp., introduced the first handheld wireless digital instrument capable of measuring secondary ignition voltages in spark plug wires, the Smartach+, model TA100 which also had the capability of measuring engine RPM without connections to the ignition system in engines with 1 to 12 cylinders and 2 or 4 strokes.
In 1993, following the success of the TA100 Smartach+, General Technologies Corp. introduced the TD101, with the same capabilities as the TA100 but also able to measure RPM in Diesel engines.
