This is the reason why I have held off buying a Racer....These coil problems have been ongoing for quite some time and according to Makro in a post I read, it was only a "handful" of detectors with these problems....This has been ongoing for months since the introduction and it should have been ironed out by now and instead of frustrating customers by having to wait for a new coil, maybe there should have been a recall on those detectors with faulty coils, if that could have been done...Their customer service seems to take care of the issue right away but still it seems like an ongoing issue with the Racer...I was a supporter of Makro but after seeing this yet again, my enthusiasm has diminished.....
