Re: require! twin tach for twin com.
These are very accurate devices. So accurate that you get frustrated trying to sync the engines down to the last RPM, which you can't. After while you just let them drift around and are happy if they are within 20 RPM. With the old tachs you would never have known anyway.
A big benefit of these tacks is that they are monitoring the magnetos all the time. If they sense a difference between the mags they will turn a indicator from green to yellow. If bad enough the indicator turns red.
A mag that checked out fine on a run-up was showing a yellow indicator from time to time. Turns out it had a bad coil and I would not have known until complete failure with the old tachs. A field overhaul of the mag solved the problem.

The digital tachs were installed by my A&P/IA. They mount in the holes left from the old tachs, and they get the signal from the wiring to the mag switches. No need to run new wire to the engines.
Mine are the Horizon brand.
