I lose signal after just a short distance in tracking. It did not do this when I first bought it. What is wrong?
There is a good chance that it is batteries, batteries, batteries. Most unit performance problems relate to batteries. Some units have battery test buttons on both the receiver and transmitter, others indicate battery condition on screen or with LED lights. Use them to verify battery power level before you spend the money to have us take a look at it. And we recommend that, even if the battery test reveals some power, we would change batteries for anything less than full power. Keep a set of extra batteries in the glove box just in case.
