Slim-Line gauges are really popular with the pilot who refuses to sacrifice reliability and accuracy, when it comes to engine and flight data. These gauges all have a bright red, and easy to read illuminated displays and can be purchased separately, or in clusters, depending on your specific needs. Designed to mount below present tachometer. The Digital Quartz Tachometer is FAA approved, has an accuracy of +/- 1 RPM, and updates two times per second. This gauge is safe and noninvasive, because it does not attach to the mag “P” lead.

Please note: Slim-Line Tach gauges are only STC’ed as advisory, not primary.
