Review on Runleader Inductive Tachometer Snowmobile Waterproof by Reggie Hobbs

Cool little novelty for my garden tractor. I'm serious. Need to know the RPM of the Harbor Freight "Predator" engine on a modified 1973 Sears Lawn Tractor that's just a tractor? But seriously. It seems pretty accurate. Featuring Kool watch reminders. Maximum retention of revolutions. And I can't forget that it keeps track of total hours. Cool little gadget that is easy to install. The first worked so well. I ordered one for the new Craftsman. PS turn it off to save battery life. It would be nice if the battery was replaceable.
