I got one too, had it for 2 years now and get to use it a bit, but I have a Sovereign GT and a E-Trac I seem to use much more. The F-75 does good in most cases I have used it, but there is times I find my GT and the E-Trac seems to do a lot better for my old park hunting. I have also seen where others been over with a Sovereign or a Explorer and say they have everything, but the F-75 seems to find some nice find they have missed.
I was always going to post a picture and a post when I have time and keep putting it off, but on a construction site where a sidewalk was taken out I didn't get to it for a couple of weeks and found out there had been 7 different people with detectors over this area including my friend JamesND with his Explorer. In less then 25 feet along where the sidewalk was I got a 1893 Fish scale, a 1870 IH and a nice diamond ring using the F-75 with the small coil setting my tones to 2 tones. I was able to pickup a few other wheaties and a merc too. The F-75 really impressed me that day, but was only able to stay for a hour or so before the others wanted to go.
