Is there a decent tachometer out there?
This might not be the right forum for this question, but I figure that multi-engine pilots are probably using a tach as much as anyone else.
I'm having trouble getting consistent readings from the tach I have. Is there a secret to using them? I had one type first, (won't mention the brand name, maybe I had a bad one), but it simply wouldn't work consistently. It was a combination DVM/tachometer. The DVM works fine. I bought another brand, tachometer only which has worked pretty decent until today, when I couldn't get the thing to settle on a consistent reading. It was all over the scale when checking top end, it would fluctuate anywhere from 6k to 15k. This was outside in bright sunlight. I haven't had trouble with it before. In fact, it's the same tach I used when breaking in the engines on the test stand, with the same props, and it worked perfect. Battery is good also. It just acted like it couldn't get a grip on the rpm. anybody got any suggestions or recommendations?
Thanks,
Randy

RE: Is there a decent tachometer out there?
Randy, you might just need to take an alcohol swab and clean the lens a little. May have a build up of glo fuel crud on it. But if you want to buy a good one that should be the last one you have to buy, get a TNC.
