F75 Digging low VDI readings.

I read a post a few lines up recommending not to dig anything that doesn't read above 20 on the VDI meter but I'm afraid I gotta disagree on that one. Last weekend My brother and i were hunting a very hard hit park in northern Ohio, he with his CZ6 and I with My F-75. One of my signals was a solid 10 0n the meter but as it was a consistant signaland was reading over 8 inches deep I decided to go ahead and dig it. After pulling out a 4 inch rusted nail at about 6 inches the signal was much improved and a couple inches later rewarded me with an 1854 Half-Dime in very nice shape. Now I won't say I go around digging signals that read that low all the time but it all depends on the age of the place. Finding half dimes isn't very common with me, the last one was an 1839 bust half dime from North of Columbus Ohio last fall but believe it or not, last weekend I dug up not one but THREE half dimes in about an hour in that same "hunted out" park, two 1854's and an 1856. Gotta love that F-75.
By the way, I was using the stock coil that comes with the machine, I haven't tried any of the others and would appreciate any feedback on which one to get first for coinshooting. Thanks, Bill.
 
I have found numerous times that good coin targets will read lower when near iron or very nearly masked by some type of iron. Very good hunting Bill and your results certainly show it.:cheers: HH jim tn
 
Disc 13, tones DP, Process DE, And in that case sensitivity was at 89. I usually never use the notch feature, I figure I should be the one deciding what not to dig, not the machine, so I hear it all and then decide. Discrimination is also something I don't use much of. As an old friend and detector salesman named Harold Cotton from Fort Worth Tx used to say, the only true discriminator is a digger.

I will start digging all signals and let you know how I come out. I skipped some iron signals this past weekend. I am digging all next time. See what happens.
 
Dug another "low" signal again today and was rewarded with a 1902 indian penny. Other than a few wheaties the only other finds of note were a 1903 indian found by my brother using his 20 year old whites spectrum and a 1939 quarter I found at 5 inches that gave a beautiful signal. The strange part is that we had both hunted this yard several times together so how in the world did we miss that easy perfect silver quarter signal at only 5 inches? Goes to show you that no place is ever really hunted out.
 
Great food for thought, you can definitely replicate what your seeing when air testing targets on the fringe of detection. I'll definitely be testing this out in the future.
 
My advocation is not to dig signals under 18 . I`m saying this because, i live in the UK where we mostly are not interested in looking for coins other than SILVER ones and obviously Gold ones. I think the majority of English Detectorists will tell you they are not interested in any other coins other than Silver & Gold ones IF they were being honest when asked. This i why i never dig signals under 18. Because on testing the signals ,EVERY signal dug under 18 has been Rubbish ones.
I am aware over in the USA your History isn`t far back enough to get you coins from a thousand years ago and your probably by & large only going to get coins from the 1700`s up so your aceptance of most coins is welcome, but over here we mostly only go for the Silver & gold ones so thats why we only say only dig signals from 18 up . Hope this clarifies the reasons for saying only dig from 18 or 20 up from us UK members anyway.
 
Man i got a ton of iron signals yesterday. Most of them were iron. I did manage 2 silvers a 1928 Canadian Dime and a 1937 Washington Quarter. I will dig some of my deep iron signals next time out.

travchance9991 do you remember about what the TID# was for the injun and about how deep it was? I've been hunting an adobe site and get a lot of signals that are solid but lock in around 10-12, so I've been skipping them, but now I'm thinking I should be digging them to see what turns up.

Thanks,
Brian

zaxfire69 were either of the silvers you dug a low TID# ? If so, how deep were they?
 
The most important key here is the depth reading. I've found that at a depth of 8+" that the VDI numbers tend to go down on good targets (which I believe is just the reduced signal strength), but I would say that there was most likely some rusted away iron (maybe just a small nail or two which would require careful investigation to find) in the hole with the half dime.

So the moral of the story is that if you get a 8" + depth reading, even if the TID# is low, DIG.
 
This reminds me of a head-to-head test I did with a friend who owns an F-4. We went to one of my turf parks and I flagged deep (> 6 in) high conductor signals for him, using my F75. He could HEAR all the deep signals with the F4 and they were repeatable, but they ALL read as iron (<12). Most turned out to be deep wheat pennies. What I took away from this lesson is that the F4 was operating at its maximum depth capability when it came to correctly identifying targets. No doubt the F75 identifies things deeper and detects deeper, but the F75 will also have a maximum depth at which ID starts to default to iron. So, there is some wisdom in taking a chance on very deep iron signals with the F75. I would only do this for targets that max out on the depth meter and that weren't obviously large targets. It would be beneficial to carry a small notebook, taking notes on what the machine is telling you BEFORE you dig and what the results are AFTER. It's fun to learn those subtle aspects of your machine, which will ultimately lead to more goodies at the end of the day. The other day, I got one of those high ID (mid to high 90s), deep iron squeals (as opposed to the usual low iron ID grunts), that make you think, half dollar?! 'Experienced' F75 users usually balk at these signals, because they 'know' it's a deep piece of rusted nail or galvinized steel pipe. But, this signal sounded a little sweeter and out popped a quite oxidized 1895 Injun! Most of the time, it will be iron or a pipe, but I was glad to be humbled in that case. Who knows, maybe next time it will be a Morgan dollar. Good luck everyone. - Jim
 
Jim funny you should mention those mid to high 90s deep iron squeals. A while back I hunted a new (to me) park and got one of those signals and thought, yeah sure, it's probably a can or some other junk, but it sounded sweet. I dug it up and out popped a 1972 clad dollar. Although not old, still fun to dig. Last week I was in the same area and got a similar signal, sounded really sweet, and I dug way down and found an old rusty pipe :rofl:

You just never know how lady luck will treat you, but if you don't dig it, you'll never find out.

hh,
Brian
 
Indians and wheats will drop down on Id for sure..now it may be junk..but if it was an old injun or maybe a half dime it will be in your pouch,,not waiting for someone else to find it..
