Seems like I've only read about the Pro Pointer just quitting, not getting less performance. Assuming your battery is fine, has anyone noticed their Pro Pointer gradually seeing less than what it used to when air testing coins? The air characteristics hasn't changed, and mine now wants to stop seeing coins at least a half inch less than when new in my latest air testing of the thing. I sometimes can't be sure if it has gone from 2(new) down to only 1(6 months old.)

If there is a degradation factor to look out for, I'll be quick to utilize my warranty and send it in. TIA, martin
