If _Mark_ can't get something to work then something really strange is going on.
My KR with Steve's 2180 has the Tiny Tach. I always wondered how accurate it was until I bought the DynaVibe and confirmed that it's within a few RPM's of the DynaVibe readout - ±5 RPM usually. It's been working for me for three years now and for some unknown period before that . . . so the battery lasts a very long time . . . at least for me. The TT wire is just wrapped around a spark plug lead - one of them that goes to the electronic ignition. I've never tried it on a mag lead. If I turn off my electronic ignition in flight I lose my TT readout, but I don't normally do that. Is there a way to replace the battery inside it? I was planning on just buying another TT whenever this one conks out since the company says the batteries aren't replacable. I don't see why one couldn't get into the case and replace whatevwer is there. For $37 bucks though . . . who cares. Anyway, I've been very impressed with it. Something so simple I didn't have a lot of faith in initially, but time has proven it to be quite an accurate and dependable little device.
