Lobo ST Coils and Silver Coin Hunting?


Recommended Posts

Does anybody know if those Detech or NEL coils made for a Tesoro Lobo ST will actually get better depth than the Tesoro coils before I go and buy one and can't return it? Any recommendations on the best coil of these 2 brands for deep silver hunting?

I have all of the Tesoro coils made for my LST, but I could never get more than 8 inches on a silver quarter even after having the detector tuned to the 9 x 8 coil in Disc mode at the factory. My buddys with Minelabs can get several more inches or so they claim. The LST was my fave all time detector and the only one I ever paid for with finds,mostly gold jewelry.Heck,it will 'see ' a mens gold ring at a foot deep air test in All Metal,so I don't understand why I can only get silver coins at 8 inch max in Disc and a touch more in All Metal?

Thanks,

Air tests are not in ground and what you get in your ground is what you get. 8" is not bad for a detector designed for nugget detecting, not coin detecting. I almost never dig coins that deep in my ground. I doubt another brand of coil will matter.

I always figured about 30% loss of depth in descriminate over all metal...this is from memory not a scientific study...

Coil manufacturers often claim better depth over stock coils but that is usually because the after market coil is a bigger size.

 

I don't believe bigger coils really give much better depth but do increase ground coverage...

Why would this detector get better depth on a mens gold ring vs a silver quarter? Isn't Silver more electrically conductive than gold? I could get 10-12 inches on a quarter in the ground  with a Tesoro Tejon but it made the same audio response on a target whether the item was an inch deep or a foot deep, which I don't like. The LST on the other hand has the audio modulation that I like,softer signal =deeper target. Now ,if I could just have the Tejons depth and the audio modulation of the LST,I'd be a happy camper...

There is a video on YouTube from Keith Southern who claims to have tweaked a certain pot inside his LST and getting the depth I want on coins, like 10-12 inches in hot ground atho he doesn't actually dig any of his test targets I noticed. .And he doesn't show which  pot it was of the 7 on the circuit board. Guess I need to try to pm him if can find his email address?

 

   I only keep my LST around cause it was my fave detector and could run rings around the Shadow X5 I bought some years back for Civil War relic hunting in Ironton, Missouri. The spot I was hunting was on top of an iron mountain.Heck, there was an iron mine right acrosss the street and another one on top of the hill during Civil War days. The Shadow was useless here, beeped every step.My LST totally ignored the hot ground and got me globs of lead, lead bullets, even got me what I later learnt was a brass cannon primer thing and these coiled up wires which must have been used with the primers to set off the cannons.

 

 

  I am having a dealer on Ebay check the Detech and  NEL 13 inch coils on a Lobo/Vaquero. He is claiming 10-12 inches air test on coins. Guess I better check his return policy if I don't like the coil?

I got my Lobo apart and circuit board exposed and was finally able to get hold of Keith S tonite.Tomorrow, I will get brave and turn the tiny trimmer pot he told me to turn and see what happens...wish me luck...I've never fooled around inside a detector before so am kinda gunshy about it..I will mark the pot trimmer position before I turn it for a reference point ..like doing the timing chain on a car I guess...wish me luck..

      Detected for a little over an hour today at a local basketball court with the 5x10 Coiltek on the Equinox 800. There were 29 dimes pulled from the ground with more left there, as my legs were feeling the up-down blues. I was going for coins and ring signals in the 5-15 range. Found one wheat penny, but nothing else spectacular. The 5x10 is like using a laser in the trash-littered grass surrounding the court. Even around a trashcan, the coins were still findable among the pull tabs and foil that miss the can.
      The 5 yen coin was found yesterday at a park; it is worth a whole 4 cents! Takers?
      Park 1, all metal, 7 recovery, 50 tones, 20 sensitivity

      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.
