Lobo ST Coils and Silver Coin Hunting?


Recommended Posts

Ok,

 

Temp was almost 70 today in late October in Chicagoland so I am packing up to go  gold mining in Indiana this weekend,  plus  I did some air testing on the Lobo at  a local park, away from my home interference issues.

 

I set the Lobo on a park bench and got out some spare change and my tape measure , so there was no guessing. I was able to crank Sens to just inside the Orange area before it chattered a bit.. I had set the R33 trimmer to max CCW but turned it back 1/8 turn. It was orginally set at 1/4 turn back from full CCW from the factory.

 

Air test results with speaker only:

 

Clad dime- 7 inch

Modern Lincoln Penny- 8-9 inch

Jefferson Nickel- 10-11 inch

Clad quarter - 10 1/2 inch

 

I didn't have headphones with me but might expect another inch with headphones and listening for weak sounds. Originally, I could never do better than 8 inch on a clad quarter. I am a much happier camper now.Just have to see how I do in the ground at this point....

I wish you a lot of good finds. Your setting could work now. I search with Sens on 10 (at start of the orange area), only with headphones. Set Disc between 1 and 2. Now nail´s come sometimes in with a choppy sound, Big iron sounds good. If you now find to much iron, set the Disc to 2 but don´t go much higher. The deeper the disc-setting the more deeper is the lobo.

I got out with my modified Lobo this weekend. At my sisters house in downtown Indianapolis, I was forced to turn SENS down to about 4.5 as the Lobo chattered too much and I could not pick out good targets. At a playground in west central Indiana, I had the same problem in a gravel tot lot, even tho I was out in the country. I was able to run the LST in Black sand mode flat out with no chatter in the gravel. Next, i tried a small sledding hill and had NO problem.This hill was thick ,rich black topsoil.I could run in Normal mode, just into the orange on Sens. No old coins but the deepest was a measured 7.5 inch on a clad dime.

  I think I will just crank the Sens down manually instead of readjusting the inside trimmer for when the unit chatters. Dunno why it did so well in black dirt vs all that chatter in gravel or in town? I am using the 9x8 coil, my favorite. I learnt long ago, to tell bottlecaps and rusty metal washers by the sound on the machine.They make an extremely high pitched sound and very hard to pinpoint, whereas coins and tabs and rings are more mellow and easier to pinpoint.

Hi tvanwho,

you have changed with your GB-mod to some degrees your Disc also. So it could be that some stones (hot rocks, slag from melting metal, mineralic stones and so on) give you a positiv signal. So you have to set your discpot so, that the stones don´t give a signal. If you don´t change your Disc-setting you can identify this stones, wenn you switch in allmetal or pinpoint. For theis stones you get a very good signal in Disc but no or a totaly weak signal in allmetall and pinpoint modus.

Sometimes the coil is no better than the detector pushing it. I've got the Eagle 2 from White's back in the early 90's and it stills has more depth than what your talking about. Just maybe you got trouble with your detector that you just can't see are hear.

 The Best to you.

      Ozzie took me out to a new site he has visited previously.  It was a working farm from somewhere in 1700s, but is abandoned now.  Things are grown up so badly around most of the property that even though the house is only 30 feet from the road, i bet 99% of folks have no idea its there.  There was so much undergrowth, hunting close to the house was impossible, so we split up and worked on areas of what would have been fields and some yard.  Pretty typical mess for around us....buried large metal who-knows-what probably up to and including farm equipment.  The sun was out, but it was brisk, alternating some blowing rain squalls...jacket on, jacket off, jacket on, jacket off.  Got a couple spoon parts, partial harmonica reed, lead blobs for awhile.  Another really loud lead blob sounding tone, but a hair cleaner, and out pops the most likely civil war era rosette for on a bit.  30 feet further, and the nicest Indian I have gotten in a long time.  love those greenies.  To end the day, found the '40 merc and '43 war nickel under a nice big sycamore.
      A big shoutout to Calabash for the videos you make...i watched a couple of them a bunch and worked this summer on FE and FE2 settings, making sure I kept the values low enough to mask as little as possible.  When digging the IndianHead, i had plenty of iron tones with it, but decided to dig because the non-ferrous was mid, and not high so was fairly certain it wasnt just falsing.  first target out was a rusty blob, then scanned again for the high tone, which was still registering, got the coin out, and re-scanned and was still getting another iron object in the hole.
      all you folks, have fun digging!

      I took a day trip today, drove about an hour to go hunt a park that I've been to before. Took me a little while to finally hit a nice hot spot. The area was about 15 ft wide and 30 ft long. Every signal was either a deep wheat or a silver. As you can see my ratio of keepers to clad was extremely high today. I'm running the Equinox 800 in my cherry-picking mode, only digging anything from zinc's up. The barber quarter was an oddball, this park wasn't founded until 1925. I hunted for about six and a half hours.

      The dust had barely settled from yesterday's hunt. Originally I had planned to do a little water hunting, then I changed my mind and decided to go back to the park I hunted yesterday. On the road, I scrapped that plan and drove an extra an hour to another park. I'm glad I did because it paid off with another multi-silver day. When I wheeled in, I saw 2 other guys already hunting. I went across the road to stay out of their territory.
         The third hole of the day was a mini wheat spill consisting of three Wheaties at the 8-9" range. I asked the 2 guys that were taking a break from hunting if they wanted to see how deep the coins were. I had left one in at 8" that was sticking out of the side of the hole to show them. They both explained to me that they don't want to see or dig a deep coin 🙂 If they can't pick up the coin with their pinpointer, they leave it,  volume clad hunters only is what they told me. To each their own I guess, which explains why I'm not hitting many coins in these parks, which is fine with me, it just slows me down. 
      After digging 8 or 9 deep wheats, I'm using a Nox 800, I decided to set Park 1-2 and Field 1-2 up with all the same exact settings to see which mode hit the best, Park 1 and Field 1 did the best, although Field 1 wasn't as crisp and sharp tone wise. Park 2 and Field 2 degraded the signal to a point I wouldn't have stopped to investigate the hit. 
      I ran the Nox in my cherry piking mode:
      Park 1
      Recovery speed 3
      Iron Bias 0
      Sens  23
      2 tones
      No disc-wide open
      Tone bin set at 21
      Very slow sweep
      These small town parks are producing in a way I didn't expect. I don't do much research, I google the town or ask someone where the oldest park in town is and go from there. So far, so good, 42 silver coins, 4 silver rings and over a 100 wheats in the last 2 weeks doing this.

      For a long time I've wondered what is a good way to search inside buildings for metal valuables hidden in walls, floors, masonry (such as fireplaces), etc.  Given most wooden structures are riddled with nails, it seems like a tough task even compared to nail infested soil.  Is discrimination key?  Has a manufacturer ever made a detector specifically for this task?  Is anyone aware of mods that can be made to standard detectors to make them easier to use in these conditions (particularly mounting of coil and control unit to be more manageable in tight locations)?

      The corn is harvested here, time to get out in the fields. I've been wanting to search this particular field right next to an old farmhouse where I dug some silver coins. Right up next to it I dug one IHP and a colonial button, figured there might be more in the field.
      I'd say it's about a half acre, don't know why they bother but a field is a field I guess. Yesterday was one of the last hot and humid days we can expect here, so why not be miserable for a few hours? 😀
      The end of the field the photo was taken from is where I dug the coin and button, as you get closer to the hunt club building it's mostly beer cans. They haven't tilled this field and they probably won't, most farming here is "no till". They may run a bush hog around the edges but that's it.
      Used the 10x5 coil as usual, it's especially good in corn stalks. I found that swinging it ahead of me on an angle is better than back and forth. I made a short video but don't see .MP4 uploads.
      In 4 hours I got some clad, one coin spill gave me a quarter, nickel, and Zincoln. The other quarter was up near the hunt club. On the "good" end of the field I dug a 1944 wheat. Near that I got a 25, thought I'd get another IHP but to my surprise I dug an old brass ring. I know it's a ring because of the crown on the metal, doubt it's a compression fitting ring. Sad there was no makers' mark or inscription, but I don't want to scrape all the crud off. As it is something put a nick in it. It does not bend.

      Here is a closeup of the ring:
      And here is the trash, one iron relic looked interesting, kind of a hook with a loop. I threw all the beer cans and slaw in the handy dumpster. The shell is a high power .17 caliber.
      Not sure how old the ring is, so I thought I'd post it.

      Back at it again today,
         But this time, I had a definite goal in mind! To intentionally try to squeeze out a few more old coins! And, oh yeah, to get rid of my now sore "detector legs" from Friday's somewhat short hunt! 
          A little side note question first! Am I the only one getting sore legs; and other parts, when digging a bunch of targets at the beginning of a season, or long hunt?? Or are the rest of you just too "afraid" of what the rest of us will think, to mention it??.... No matter, I'm sore, and "Proud" of it!!🤣😂
         Anyway,
        I went out today with a more focused purpose, and more time to put it into action! Did about 5-6 hours today!
         Same setup, with the Vanquish, and V8 coil! I more or less wanted to repeat the other days hunt, with a wider range of coins, and some added emphasis on finding some oldies, in some curb strips!
         Our oldest neighborhoods are generally from the 1920's forward! And have had many roadwork and "beautication" projects, that have destroyed prime "old coin" hunting grounds! But you work with what you got!! So knowing that some of the "tree lined" streets still had their original trees, (i grew up here), I would focus on them for the oldies!! 
          Between those, and general hunting of this park, adjacent to some of them, I should at least, be able to get a few shallower "older" coins!
         My V8 park hunting produced plenty  more modern coins, as expected, and was good fun! But also, self-limiting, as that coil doesn't get the depth needed for those elusive oldies that may be there! The soil under the St. Augustine Grass here, tends to be very rich, and easy to dig, with lots of earthworms, so the coins get buried pretty deep, over the decades! Not unexpected, but i was jumping back and forth, from the strips to the park, so I kept the same coil on the detector the whole time! I also have the V10, and V12, so I will go back with those at some point, and test my theory! And of course, the Nox!!
         So, to the Good Stuff!  One each from just beneath three different "parking strip" old trees! No deeper than about 6 inches, but hidden up against large tree roots! And thankfully, not grown into them!!
      A 1942 Silver Merc!! 💖🎊 No nail board test from Monte this time!!🤣
      Two 1919 Weaties!! 💕(Same date, two different trees; weird!!)
         So now, I at least know that my theory; while producing only a few oldies; is actually sound enough to follow-up with, In future hunts! I can live with that!!
         The rest of the hunt produced alot more pennies than I wanted to dig, thanks to two fairly large "penny dumps" in two separate curb strip locations! (Over 100!!🤯) I basically just sat there with my pinpointer, and located them till my legs got numb, and I had enough!!😂  Still more in both spots for another round! I guess there are non-detectorist that hate the pennies as much as we do!!🤣
         A rough count puts it around 140 coins total! And I skipped alot of penny's, believe it or not!! So I'm "Tremendously Happy" with the 2 Silvers, and 3 older Wheats, over two days! They actually give me some hope for more now! Or maybe, those where the last two Silvers left in Florida!! So I can leave now!!🤣😂
