Trashy 1918 park, any suggestions

[sonny32]

Good day folks,
Last few days I have been trying to cover a park that has been there since 1918,,It is an old plantaion sitefrom the early 1700's till the cival war and it was burned,and the site is now a wayside park for travelers and locals,,Seems that over the years so much trash, Aluminum in every form bottle caps pull tabs, lead bullets, everything you can name I have dug this past week,, including some pennies, 25cent pieces and some copper sheet,(large pieces maybe from a roof or something).. I have the X70 and tried to use a wheaty penny, a pre1972 quarter,a 1940 nickel and a 4 gram gold nugget to preset the Pattern number 2 of my x70,,,Now I have not been out to try it yet as it has been raining,, I'll let you know how it does,, I tried to do this in the field but did not have the patience at the time... Anyway has anyone else done this,, If things work right I should not get any hits but good ones.. What do you think??Oh yea i use 9 inch 7.5 coil...
Thanks in advance

You can set a Pattern that only provides an audio response on those targets that "align" with the notch segments you set as accept. You indicate you will set yours to accept a Wheat penny, a pre1972 quarter, a 1940 nickel and a 4 gram gold nugget. The problem is, many of the "trash targets" you described can also fall into those same notch segments as the good stuff you are looking for. For example, you said the site included aluminum in every form bottle caps pull tabs, lead bullets and some large sheets of copper. Depending on the size and shape of the aluminum and the lead bullets, they can read anywhere from your nickel to the quarter. The large copper sheet should provide an overload tone. But again, that depends on the size and depth of the target. Bottle caps, if aluminum, will also fool you into thinking they are coins. And different shaped pulltabs will read all over the map. Sorry, but that is just the way it is. Not only with the X-Terra, but with every other metal detector on the market. Here is a link to a post I made some time back, telling about what we might find with specific TID's on the X-70. http://www.findmall.com/read.php?55,569213,569213#msg-569213

I wish you all the luck in the world. But it is going to be a tough hunt. On the bright side........if it were easy, someone else would have already found all those coins!

Thanks for the info Digger,,,,,
Now that I have thought about it, with the amount of junk in that park, I guess I might just set the sensitivity low and dig the strong targets,,,Its a shame, but maybe one day a better detector will come out that will only identify coins and gold

You may wish to look into a DD coil. There are several available. I don't have the 10.5 MF DD yet, But I do have the 5 x 10 and 6" HF DDs and the seperation is great, especially with the 6" DD.

I agree with Digger, what your planning on doing just well not work because of the many different types of trash items that well be at that park.

What I would try doing at a place like that and since your using the stock coil is to notch out everything below number 26 or 28. Forget about going after the nickels and gold rings for now. Swing your coil super SLOW, checkout every signal that you get and decide if you want to dig or not. Look at your depth meter a lot. Dig all signals that are 4" to 6" and deeper. Good Luck

To further complicate things...a coin in the ground might read differently than the same type of coin in air or in an otherwise "sterile" environment. Too often a goodie coin will bounce around or read high/low depending on mineralization, depth, partial masking, etc. If you are too strict with your custom notches you'll miss them.

I agree with Mark........go mega slow and dig everything over 4-6"

Now that is a good idea,,,Dig the deep one's... as for the coils I have almost all the coils for the x..The one's I don't have are the 9" con 18.75, and the 10" round DD 18.75 I have the rest.. So coil selection is not a problem. I just thought I would try the Manufactures recomened coil,,as per the Coil selection Guide,,,But I can see that before its over I will have tried all of them,,cause this looks like a challenge... If anyone in Virginia wants to help let me know..
Thanks

I don't mind the trash as long as it stays in the ground where it belongs, and doesn't trick me into digging it. FWIW, here is what I would do. --- 6"DD coil, slow motion sweeps, only dig the deep targets, and before digging, go to the AM mode, do the pinpoint, and watch the ID#, and listen for low tones(iron). Negative ID #'s, and or low tones while in the AM pinpoint mode, it stays in the ground. --- Pos ID #'s, with high tones, I'll dig. ------ I give credit to the posters who put this info in the FaqFaq's, (I'm not that smart)

I would use either one of the 6" coils or the 10"x5" DD. Go slowly, swing slowly and move forward slowly. I would probably approach it by working a small patch at a time, that way. after short while you should be able to tell if there is much good stuff in that particular patch. If not, select another small patch....sounds as if there's junk all over the place and you may just have to remove a good portion of it to get to the good targets...could be a lot of work, but it is probably worth it. If no-one else has removed the junk, then they haven"t removed the coins and jewellery next to or under it. Good luck.
