Disc. with F75LTD/DST

[shooter]

Sill working that old drive in movie, can't get rid of pull tabs with the F75, Fisher couldn't give me an answer. Any tricks out there . even at max. disc. there still there but out of the ground there gone, could it be to high SEN.?

 

[MuddyMo]

Try a smaller coil?

done that, they just don't get wiped out getting 10 to 15 in a hole this drive in is super garbage., thought lowering SEN. would help, that didn't work. any other ideas. still ton of silver there, only dong the playground area, haven't touched where the cars park.

Use a concentric coil. Then, either use the id #'s to recognize it and pass the obvious ones, or set disc and use a quick sweep over the target to break it up or make the signal disapear altogether.
You may not be able to completely avoid the really deep ones, im not sure any machine can accurately discriminate when it gets very deep. Those iffy signals could be anything. If you are digginv deep iron, id say thats a problem. Passing on deep tabs may cost you some silver coins too.

I have used many machines. The f75 with the 10" concentric coil, or even just a regular f70 that comes stock with the 10" concentric, is an exellent combo, and will be very hard to beat as a coin, relic and park/ trash machine. Its almost the perfect setup as a universal do it all machine imo. I often run it with low, like 50 sensitivity unless i need it to go really deep.
