I have the rocky mountain micro monitor which records hours and I have a
tach that records hours.  I end up using the tach hours for my record
keeping since I can read it without turning on any power.
Gary Melton LNC2 400 hours on the tach and about 10 hours less on the Rocky
Mountain MM.

A discussion has arisen regarding the need for a Hobbs meter in our
airplanes.
One builder has suggested that all that's needed is the time logging
function of the Chelton Sierra Flight System.
While I'm very much a gadget kind of guy, I'm thinking the ol' tried and
true, can't be reprogrammed, reliable hobbs meter is just the ticket.
