Hi Steve, the bigger bits I've had with my F75 SE reads at about 22, but I've had gold all the way to 14 and once at 13. They are quite small at that reading lol.

The small nuggets I got would bounce from 13 or 14 to higher numbers and back. An "iffy" reading. But if I got a solid lock at 13 or 14 it was a hot rock or ferrous trash.

Steve, I can't thank you enough for your unselfish assistance 'tuning' me in to my new F 75 SE at the second week of Ganes Creek this summer! You shortened my 'learning curve' by several days in about 15 minutes and made me a believer,.. the F 75 is a great gold detector and a pleasure to swing all day long, amped to the max in a remote location, once you accept the 'chatter!'.

Steve,

Rob Young from NorCal. I love the F75 I bought from you. So far, I have taken out about three times while in gold country. Though I have only spent about two or three hours detecting with it (not counting finding a target and needing to crevice or dig the target out), I already love the machine. I use the 5" DD coil with Boost all the way up to 99. I have tried JE and DE modes, and different discrimination levels (4-12 normally). I am still learning the machine as it is way different than my Etrac!

Are you still using the F75 on your hunts? Have you made any videos of hunting with the F75? Has the larger coil lose much sensitivity to small gold?

I guess I have pelted you with enough questions! Happy prospecting!

Rob

Hi Rob,

Glad you are happy with your F75. I will be using mine again this year at Games Creek and do plan on shooting video. I use the stock coil at Ganes as tiny gold is not my goal at Ganes.

Unless you have lots of trash, or bot rocks you want to tune out, use all metal. It is smoother and more sensitive.

Steve,

I took out the F75 today and tried all metal mode. To be honest, I had to experiment on how to get it the right side options. I know I need to keep chugging along to learn this machine, but All Metal seemed to sound off on rocks and any uneven ground. What sensitivity do you run on All Metal Mode? Any special settings or is it just me needing to adjust?

Thanks,

Rob

Yeah, you need to read about how to ground balance in all metal mode. If you are in bad hot rocks disc may be easier for you. The higher the mineralization, the lower the sensitivity.

Hi there

Someone please help me.

Just bought F75 special edition for my dad. He does not speak the language and I got the task of working out how to use this machine.

He is an active treasure hunter with home made equipment this is just too much for both of us to understand.

How do we start using it. How do we know what we are reading?

It beeps on anything?

Thanks a lot!!!
