They fixed the battery box with new springs and foam and I think a new battery door. They had to replace the new coil that they replaced last time. Man I said don't even think about sending me the detector back without testing and checking it out. I said to him I got over a 1000 hours on the F75 and I know what the machine will do. He said he would be sure that was done. I hope I get another 1000 hours out of it. I will be headed back to Fl. shortly and be back on that bad black sand beach I hunt. Maybe I can pay for the f75 a couple more times like I did the last time I was over there with the Gold I got off that beach. I will be hunting it hard. I am going to take my newly Modified tone ID 6000 XLPRO,SE, Excal ant Xterra 70 back over there also. I am going to hunt the TR Mode and G/B the 6000 XLPRO to the mineralized black sand beach. I want to see how it will do in TR mode G/B that way. If not I will hunt in Sat mode and in track. Man I love that tone ID Mod on the 6000 XLPRO thanks to Allan. That is really nice. I will check the F75 out before I leave to make sure it is fixed this time. If not Roady will be back on the road again. You can bet on that. I have confidence that they fixed it right this time. : : . Fingers are crossed. Later HH Jerry aka Tinfoil
