CAN SOMEONE TELL ME ABOUT THEIR EXPERIENCE WITH THE F75 IN ONLY THE DRY SAND AT THE BEACH

[usa-usn-vet]

I UNDERSTAND THE F75 IS NOT A BEACH MACHINE BUT CAN IT BE SOMEWHAT USABLE IN DRY SAND AT THE BEACH, FOR COINS AND POSSIBLY JEWERLY ONLY IN THE DRY SAND AREA. ANY HELP WOULD BE APPRECIATED. THANKS

I had the regular F 75 and of late the LTD and both worked very well in dry sand. And, with some tinkering with settings, like setting the ground balance around 15, it is more then "somewhat usable" in wet sand. Have fun and good luck! HH jim tn

Manual Ground Balance in all metal mode......... It's a little chattery but worked fine on Tybee Island beach in Georgia

I did have to turn the sens down some ............ Also had to swing it a little slower.......... I used........... De Mode. JE mode was to noisy.. Two tone worked well...

Many Pulltabs hit as good targets, but they were very deep and old..........

THANK YOU FOR THE INFO.

Yes, what Elton said about manually ground balancing. If it is out of range of the fast grab, go to manual ground balance. Some of the dry sand can ground balance around 70 to 80, some around 45 to 50, depends on the beach, I'll normally hunt in discriminate mode in the dry sand and in all metal over the wet sand and watch the ID number.

On a salt water beach, as you get towards the damp sand, the ground balance point quickly drops into the 20's and teens then single digits over the very wet sand. That is where it tends to false more on the ground changes so I go to all metal. Best depth is at best ground balance. Need to stay on top of the ground balance with this beast. Because of that, I'll not do as much zig zagging over the damp to dry areas with the F75 as I do with the multi-frequency beach detectors (like a CZ). With the F75 I'll run more parallel to the wet / dry line to keep a more uniform ground balance point, then move further up the dry area or more towards the wet and adjust the ground balance accordingly.

Over the wet salt sand, the ground balance can be on 0 or 1 (there are 5 clicks per numerical digit) and setting is pretty critical to getting best depth; and that is very good depth. With the low ground balance settings over wet sand, iron has a unique sound. It gives a broad echoing or booming sound. It tends to ID strangely too; giving bouncing numbers all over the place and having some 99 readings in there. Dig a few and you learn what the iron sounds like; then you will not dig very much of it if any; even in all metal mode.

For just dry sand, it does not require a lot of adjustment. Set it up and hunt. Adjust the ground balance if you hit some heavy black streaks. For hunting the blanket line where the sand is starting to get damp, it requires more work to stay on top of the ground balance setting.
