Sound of a deep coin signal?
- Thread starter bottlebum
- Start date
although, it would be interesting to see what would come out of the ground.
When I first got my F75 I could not find nothing over 4" or 5" deep. I was ready to wrap it around a dam tree, but at that price I had to lay with the machine. I learned to turn the SEN. down and I started getting the depth everybody was talking about. I posted a picture of what I got today ( I am not a coin hunter ) I hunted about 1 hour. What I was wanting you to see was the little brass Knapsack rivet at the bottom of the picture. It was 8" deep and I was getting a good sound and good numbers. Numbers in the 70's. To top it off I was running the F75 under electric Co-Op lines. Had the machine set in the DE mode. Sen. 70. Tones 2. Dis. 5. Fast Grab was in the 60's. If you can hunt in the Static Mode it will get down, but like today I was in alot of trash. When I am in a open field hunting for relics I have busted bullets at 12" in the Static mode and they sound like they are on top of the ground and the machine will read they also. Anyway lay with it. It will do the job.

Use a butcher knife and make the holes as small as possible-finnesse. Always save your trash
to show the park Super-I find live bullets, hypodermic needles, crack pipes, pieces of wire
sticking up from under the grass, beer cans cut into sharp shreds from the lawn mowers-
broken glass from beer/wine bottles. I pick up everything I come across-the park employees won't.
Really a safe place for kids, huh?

Thanks to all that added their settings and ideas. That is one reason I signed up here. Folks are willing to share info with other hobbyist to help them get better. I am going to try several ideas mentioned earlier in this thread and see what comes out of the ground. Lower disc, no notch (maybe LOL), try the multi tone setting, dig all targets in a 4X4 area and test against the ace for depth. I will report back later. Have a great Sunday. TMAN...

Did my little experiment this morning. I set the 75 up at 6 disc. sens 70 fast grabbed. Set the ace up in coin mode, 6 bars of sens. I focused on dimes only. As I got a signal with the ace I marked the spot. I only had 2 that showed at 6 inches. I found appx 12 targets in a relatively small area. I scanned with the 75 and it picked them all out with good target ID, 70-72. one of the 6 inch targets bounced to zinc but it sounded off with no problem. Now, all of them came in on pin point at 4 or 5 inches. I dug carefully to see where exactly they were in regards to the surface. None came out deeper than 4 inches but the one thing I found interesting, is that most were on edge or near on edge. Only one was at the bottom of the hole laying flat. 6 holes provided pre 82 pennies 6 holes provide clad dimes.
I then took the 75 first and found four targets that rang out as dimes. One was at 6 inches when I pinpointed and 3 others came in at 5. I took the ace to them and it hit good on 3. The one at 6 inches was iffy, it bounced between zinc and a dime and was broken. Dug them all and all came in 4 inches except the 6 inch. It came out at 5 inches and was a penny.
I spent a few minutes just hunting with the new setting and even though I like to notch out tabs, I left it open. The area wasnt to bad and ended up with 25 coins. I will continue to try this setting to see if things get better. Thanks for reading. TMAN...

Bottlebum:..... Fast Grab GB........or better yet before you fast grab GB are you going to all metal..That makes a big difference in GB..It is not accurate in Discrimination mode in the initial hunt ground..but after all metal GB then you can fast grab on the fly..It's easy to do and often does help a lot...The ground does change a lot....Or if your using discrimination try preset GB thats set at 90..You may have severe ground....
Try factory preset...sens at 70, shoulder to shoulder swings in De mode...Turn your disc to 6 or go above 28..depends on what you are looking for..Go to 4H tones, watch your consistancy meter and do not dig unless top reading or 1 below..on consitancy..Mine is very accurate, and saves me lots of trash digging...
Also you can go to tone settings and try the Dp tones..It will scream on the deep silver, and deep clad....or pennies...If you are getting a lot of not findable targets turn the sens down..the target is there your just not digging deep enough, or it's really tiny.

The F75 id's tabs as coins if the circle part has the tail attached....Those are really old ones and are not total Aluminun in the mixture...But if it were a Seated dime you were getting mixed in those tabs you would hate to miss it..Bc mode helps a little with those real old tabs...and somewhat on rusty caps..
I went out for a little while and found a few clads but had to cut it short because it ended up being a busy park day. There were just too many people running around, for my liking. I did try the Dp tones and kind of liked it. Reminded me a little of my Sovereign. I need to start carrying a notebook along so I can jot down settings as my memory isn't the greatest when it comes to those things. I do remember that I couldn't run with the disc. any lower than about 6. If I did, the machine became real unstable. I even tried different frequencies, manual GB and fast grab to no avail. The only thing that quietened the machine was to raise the disc. I did have an instance where I was getting a broken quarter/dime reading in the 90's and was able to pinpoint it. I thought it might have been silver so I attemptet to dig it up. Dug down close to a foot but pulled nothing up. I was still getting a broken signal from the hole when I give up on it. A probe would have been nice because I would have been able to tell if whatever it was, was on the side of the hole or further down. It's pretty amazing how sensitive the machine is and I have no doubt that it can find a real deep coin. I think that I just haven't come across one yet.
The last couple of hours of the day were spent at another park, with my Sov. GT. I felt like I was neglecting her so I took her for a little walk. We ended up finding about $3.00 in clads, one wheatie and a 1947 Canadian penny.
I think that just like trying to learn my Sovereign, it will take awhile to learn the F75 and when I do, there won't be anywhere safe for a coin to hide.

seriously...deep coins will give a nice smooth audio usually, even if they are partially masked. They may not Id very well, but will usually sound good, everything else being equal. Deep signals that sound broken or kinda short and sharp are often iron. Virtually every deep signal I've dug thats has high VDI's, but with a kinda harsh and a bit broken signal has been iron . the key is the audio response. Dig a few of these signals and you'll see what I mean.................... Streak!
turn it up till just starting to be unstable..You will not believe the small objects you will find..small snaps for old blue jeans at 7 8 " honest...Found a football cleat at 14"....clad dimes in a reworked football practice field...9"....and still beeped when raising the coil to 12"...Read 72..solid
I'm gradually becoming a believer. I've run into a few clads that were in the six inch range and give off an unmistakable, good, loud signal. I don't think the machine will miss much if anything in the ground.
Today, I tried the All Metal Stat mode but got a loud tone that I couldn't get rid of no matter what I did. I'll have to read the manual again to see if I set it up properly.
By the way, I got me a new digger today. I get some funny looks from some of the old ladies at the park but I just tell them I work for the parks department and then they leave me alone.
