Review on 🚤 Faria 39004 Kronos Tachometer: Accurate 6000 RPM Gas Gauge for Boats - 4 by Brian Price

Installation instructions could be better; More detailed instructions for this particular model would have helped. The pulse change switch was well marked, but the fine tune connector was hidden by a sticker on the back of the wheelbarrow. I called Daria's tech support to check what heart rate setting I needed with the 6 cylinder running as the RPM was high at idle but about 1000 rpm too slow at 3000 rpm. I checked the Faria tach readings against my tachometer, which I know is pretty accurate. I tried calibrating it with the fine tune port and I got near idle readings with the settings, but on the dial the Faria tach reads 1200 too low. It was an expensive sensor and I bought it because Faria has a long history and reputation. I hope I just got a bad example, so I recommend checking the calibration with a gauge you know to be accurate. If I took the Faria's odometer reading for what it was, I could easily run the engine at speeds that could have caused serious damage or catastrophic failure.
