Deep wheaties with the F75 - all metal mode lesson

[ziphius]

Hey fellow Fisherites,

A lot of you already know that the F75 goes deeper in all-metal mode. I learned a good lesson upon returning to a site that I've hammered over the past several months. Decided I was going to go all-metal and dig only deeper, iffy signals that bounced around. The result was my oldest coin yet, an '11-S wheatie and two other 20's wheaties. Also found an interesting pin. The deepest wheatie was 9 inches (no exaggeration, I've measure my hand and it is 7.5 inches in length) and the other two wheaties were 7-8 inches. All this in bone dry soil. The target IDs bounced around from the mid 50s to the mid 60s on these and I may not have dug them in discrimination mode. I like the fact that the F75 all metal mode still gives you an ID readout, because you can still cherry-pick targets that way. Kinda like lowboy said on this forum, if it is bouncing around and the ID is 25 or higher, dig it!

On a good many of those truly hammered sites about all that is left are the iffy and deeper signals. Most, not all, but most of the easy pickins are gone. I've found, though, the F75 gives a decent enough tone and id on those iffy signals to dig. I, in fact, dug several this morning, of which, 2 turned out to be silver dimes. Both were in the 6-7" (small coil) depth range and one was completly on edge and the other was about 1" away from a rusty screw. Both were somewhat bouncy, but enough 70ish readings to dig them. I was in de, though, not am. HH jim tn

Thanks Jim in TN. I'm focusing my efforts on the deep, iffy signals these days. By the way, I was switching between DE and all-metal mode on the same targets before digging. There were a couple of targets that were too weak in DE (and JE) mode that I would not have dug unless I was in all-metal.

I use am a lot myself and love the id aspect the F75 has in am. Nice digs, by the way. HH jim tn

I pay no attention to the ID on those mellow deep signals. If I get any kind of faint signal in all directions (left, right and the same 90% from the original signal) I dig it. I love getting those kind of signals. Nice finds.

keep on diggin'

I dig a lot of deep iron, just to make sure it isn't something else. So far, the F75 has been accurate on those IDs. Curious to know if anyone else has dug deep signals that read below 20 consistently, only to be suprised by a silver coin or otherwise.

I was recently using a borrowed F75 at an old one room school house site. I was hunting in highly mineralized soil that was littered with iron and had nearby powerlines. Therefore, I could really only run in the DE mode with the discrimination at about 6 (not in high gain mode) Deeper wheaties at say 7 to 8 inches rang up in the high fifties/low sixties. I got one signal that was consistently bouncing between 27 and 31 and it was deep. I thought I might have a nickel. I was surprised to find a real nice 1874 Indian Head at 8 inches. There were no other targets in the hole masking the signal. From then on I definately dug any deep signal above 20.

Most units go deeper in all metal and if your just going by sound might as well buy yourself a unit that costs about one third the price...Certainly good info and whatever works I would think...Seems like some of the fellows are getting excellent depth in Disc. and one guesses thats what a meter is for..

THE F75 IS NOT YOUR RUN OF THE MILL DETECTOR IN ANY MOOD YOU RUN IT IN..SO WHY SPEND LESS AND GET LESS IT WILL OUT PROFORM MOST OF THE HIGH END UNITS IT IS LIKE IN THE TOP THREE OF BEST UNITS OUT THERE!

This one was at a different site in discrim mode (sens = 75, GB = 85, DE mode, delta pitch) and rang up high 60s to low 70s. Weak, but repeatable signal under the roots of an old pepper tree. Turned out to be a lawnmower clipped 3/4 wheatie! Interesting thing is that the wheaties from my original post rang up in the mid 50s to low 60s range, but that was a different site with different mineralization (GB = 67).
