I started reading this forum in early June and bought an F75 in mid July. I tried all the tips that appeared in this forum, but the unit was excessively noisy and TID number jumped all over the place even when I dropped the sensitivity down in the upper 20's. I finally called FT and they had me speak to Mike Scott. He said I should send it in and have them take a look at it, so I sent it off on Aug 21 and got it back on Sept 5. They said it was a defective coil and put a new one on it, as well as a new foam cover on the handle (not sure why they messed with the handle -- are there wiring connections under the foam, so that they have to cut the foam off to work on them??) Anyway, I put it together that night and tried to use it ... but now there was no audio...none! There were TID numbers showing up on the screen and everything appeared to be working except the speaker.
I suppose the technician had at some point disconnected the speaker and forgot to reconnect it.
I called them the next day and they issued a call tag to have it picked up and said it would be a priority repair. UPS came and got it on Sept 7. It will probably reach the factory today or tomorrow. Hopefully First Texas will get everything right this time. It has been a very disappointing experience so far. It is the most expensive detector I have ever purchased and has been the least reliable.
