Product ReviewsTrail Tech - 742-A00 - TTO Tach/Hour Meter, Black

Trail Tech Tac

I used the Trail Tech TTO on my motorhome to monitor my Onan Genset rpm. It was easy to install and I lengthen the feed wire about three feet and it worked fine. The unit allows me to monitor the genset to insure it stay in the recommend rpm range and I can insure that the units is running as I drive down the road. I looked a other options but there size may it hard to find a good mounting spot, as small as this one is I was able to mount on my switch panel above the start button for the generator. I'm thinking if getting another one from my Honda Express scooter I use at the campgrounds.Read full review...

I love it.

the one thing that stood out to me was that it was battery powered. the battery will probably last for years.

Just hook up the input and program it... and you are off to the races...

Trail tech tachometer

Seems to give inaccurate RPM readings that fluctuate wildly. Installation instructions are OK but no technical specifications on how it operates. Is it calibrated for 4 strokes? Is there a battery inside that might need replacement? No info about these details at all. Very disappointed.Read full review...

Nice little tach

So far it's working great on my boys Drr 90. A must have for tuning clutch engagement.

Did exactly what is was supposed to do.

There is a slight lag for the gauge to catch up with the revs, but overall it works perfectly.
