Hi,

I just read an older RCM article that compared the Hangar 9 tachometer very favorably to the TNC tach. The Hangar 9 tach is 1/5 the cost!! I would appreciate any comments on this. Is the Hangar 9 tach that good? Should I buy one? I'm pretty tired of the sporadic readings of my GloBee tach. Also, is there any way to calibrate tachs besides using household light? I have had tachs that read exactly correct using household lights, but read 400 rpms different when taching an engine. Any advice will be very much appreciated.

Thanks and Happy Holidays,
