I enjoy my F75. I have spent a few sets of battery's in hunting and have a few working setting I trust now. I usually hunt parks and haven't been nugget shooting or cache hunting with it for a few days. I have finally found some old silver coins, but those aren't in this weeks totals. I did remove what lil trash I did dig, and all new coins that will work in the coin star machine. Even in the most trashy areas, I can use my 11" coil and still pick out good signals, on top of or right next to pull tabs and bottle caps. I still dig a few bottle caps and pull tabs, but not very many and happy with that. Now my pinpointers are acting up so I have my 5" inch coil on now, and still digging just as many coins if not more with it. I found a few pocket spills today, was nice to get out and hunt with Jeff again. Jeff is a good luck charm. he hunts with the T2. The T2 is really a great machine also, Jeff pull some funky looking stuff out the parks we hunt for sure. Jeff digs a lot deeper than me too. Without a pin pointer, I wont dig any 11" inch targets. No pennys at 2' feet this week. But I wasn't in all metal mode either. Im happy just hunting the first 6" inches or so. Jeff kind of gets aggravated as I pull coin after coin out of the ground, and he is pulling old tin cups and candlestick holders up. I haven't went deep yet......lol. I just barely turn this thing on, and go. The machine is very accurate it ID and depth when I do this. The 5" inch coil really settles the machine down too, its very quiet. So quiet I wonder sometimes if its working at all. This unit was bought used, and I have had it about 6 months. I hunt the desert, and parks of this area. I do have emi issues, that can be overcome. If I want this machine to go really deep, I have to get away from the power lines. All Metal mode is deeper than the disc modes. There is one mode that is super sensitive and can only be run in the desert. This si a older machine without the power boost mode. I cant imagine this detector ever hotter. It isn't a minelab, or a AT Pro. But if there was a machine that could do it all, the F75 would be close. I don't count how many coins I found, I count trash to coin targets. It lets me know if I am not overloading the coil signal and causing it to miss or false on targets. Again, this is about half of what I have found. The good looking change and eyeball finds are in a bag awaiting the coin machine at the bank. Thanks for looking.
