Tachometer issues

[savarese1]

We have 1972 DD8V71's The tachometers which I can only assume are origional do not stay in adjustment. I have hd them adjusted several times, but the adjustment never lasts long. Any suggestons on digitl tachometers or any kind of suitable replacemet? Thank you.

We have Aetna digital tachs, good people to talk to and have been happy with the tachs. Mine happen to be 32 volt at the lower helm and 12 volt at the upper helm. John

I have Floscans which have digital tachs. Unfortunately they went under recently but luckily I had the gauges re done just in time
