It's high time you invested in a precision chronometer for your aircraft. The AT660100 digital chronometer (LC-6, Astrotech) is designed for the demands of VFR and IFR flight. This 5-function chronometer is aircraft powered and mounts to the panel, with an internal keep-alive battery that has 14 and 28-volt lamps.
The Astrotech LC-6 features a customized large scale integrated circuit (LSI) chip on a single circuit board, with several hundred transistors. This simplified design results in exceptional performance and reliability. The circuitry is not affected by vibration, friction, dirt or wear that is found in mechanical clocks.
