RE: RPM Guage


I have that reliability direct tach- it works fine in contact mode but the optical mode only works in low-light, as in, inside a bulding and artificial light.

Tried to get a reading on the weedeater head outside and it gave me nothing but garbage.   Same with the little lenz VAWT in bright sunlight.

Still working though the issues; it eats batteries fairly quickly.

Cain't get to the UK version of the bike comp link;  if it'll read crank revs it oughta work for us

I purchased one of these that someone in the group suggested but I don't remember who?????????

http://www.reliabilitydirect.com/tachometerproducts/RDI-TC802.htm

It was about $60.00.  It uses a small reflective tape.  I haven't had a chance to use it yet however.

I've been using this with an industrial prox sensor, but it may be a pricey way to go.
