Fisher f75
After using the F75 for 6 months I can tell you that if you take the time to learn it, you'll realize that it's a great detector.

My silver coin finds have gone up tremendously while the trash count is down. I still get fooled by the occasional rusted bottle cap, but not like I used to. It just takes time to learn, and I still learn something each time out.

Experimenting is the fun part for me. When I get a signal that I'm sure (at least pretty sure) is a good target, I swing off the target, change mode and swing back over the target to see the response. I do this again and change sensitivity and check the results, and one final time with tones to see the different response. Of course I don't do this on every target, but I still do it at least a few times an outing.

The best settings to start out at are the factory defaults and start digging. Pay attention to the VDI and the subtle tone differences between a pulltab, bottle cap, coin etc...

After you get the hang of the basics, start boosting the sensitivity and hunt for a while with those new settings. When you're fairly confident of the target id under the coil, then you can start experimenting.

I still have to go back to a lot of places I hunted when I first started with the F75 because I've learned so much since then that these will be like new places all over again.

My usual setup for turf hunting is Disc 4, Sens 95, Mode JE. I use different tones depending on the site... 3 tone in heavy trash,
3H in moderate trash, and 4H in old sites with moderate trash. Keep in mind that the Sens and Mode are pretty much dictated by the site, so you might have to tone these down a bit, but you'll figure that out after a few trips out with it.

Good luck and feel free to PM me with any questions.

It's going to depend on your soil conditions and search techniques. I like Disc of 4, BC mode, 3H tones and sensitivity as high as I can get without excessive falsing. In clean areas I'll go to default mode and 2F tones with the Disc still at 4.

When I first bought the F75 I played around with notches and discrimination "masks" but since I got used to the display numbers so I trust them I prefer to see and hear everything. Sometimes I dig "hunches" and they pay off as jewelry.

Best thing you can do is bury a coin test garden and see what settings work for you. The F75 will hit quarters past 10", on a good day 12" either flat or on their side. It is a heck of a coin shooter once you get familiar with her.
