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?

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...

The Gold Bug Pro also is noted for soft responses on silver compared to gold. I find it unremarkable that coin detectors would do better detecting coins than gold detectors.

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..

      Whooo, what a week. Back home from the beach, I didn't post my last hunt but I found .99 in change. 51 coins total, 3 rings, military button and some small stuff. No silvers. 😵 Got a 50 Centavos piece and 1 South African Rand, so I scored over $5. Oh, and an Anvil...
      My wife got food poisoning (she is ok now), my RV water heater element blew, and the outside faucet decided to crack and blow the knob out. Filled the underbelly with water. That lovely trifecta made us decide to head back a day early.
      I love beach hunting! It must be my luck but GB never went higher than 10, I only got EMI near a water tower with cell service on it. Clean, clean beach. You got what the Equinox said you did for the most part. Got many more beaches in my future!
      Today I hit the farm, decided to grid a farm house where scouting didn't turn up much. All I found in 4 hours was one 1994 dime and one button. I got a 36 on the Equinox, thought "yay!" And dug a huge crudely cast lead ingot. 😀 It's about 3" wide and is heavy. Yep, back on the farm.
      I guess we all have these days, you should see all the bottle caps and aluminum I dug to get this. Yikes!
      When I got home I had this waiting for me:
      It's a 1954 silver quarter cut to the Equinox coil shape. It came with a bead chain, I replaced it with a snake chain. Thus far I have only found two silver coins! Maybe it will be a voodoo talisman for the future. 😀 I thank everyone yet again for their advice and encouragement.

      I've been experiencing lower yields due to sites being detected, by me for sure and there are also signs by others previously.  SchoolofHardNox's success on a beach using the Minelab GPX 5000 reminded me to re-read Steve's treatise on using the (in his case original big box Pulsescan) TDI for coin detecting.
      I just a few days ago stumbled upon a promising site where extra depth could be key.  It's a schoolyard going back at least to 1955.  Unfortunately as is the case in many of my public sites, it has a history of backfilling.  From aerial photos I see than in the 50's it was grass/sod covered but in the early 60's they put down gravel.  The person who told me about the site (a person who walked up to talk when he saw me hunting a nearby park) said he was a student there 45-50 years ago and at that time it was (again) grass/sod.  I did a one hour survey hunt with the Minelab Equinox (11" coil) and encountered a couple inch thick gravel layer about 5" down.  I did find one Wheatie below the gravel, but 7" is getting deep for my detector + soil mineralization combination so if coins remain from the 50's (pre- gravel layering) then I expect I will do better with extra depth (and that may even be required).
      One thing I've found in my detecting of these older sites -- there are always nails present.  So even if my TDI/SPP can deliver in the coin category it's going to be signalling on a lot of nails.  One of the tricks Steve used was to set the conductivity switch to high conductors (low tones) but the TDI/SPP doesn't have that feature -- I will be hearing both high and low tones.  This is a dual disadvantage -- extra tones to have to mentally tune out but also extra threshold noise since both parts of the signal spectrum will be contributing to that as compared to only half when the conductivity-low switch selection is made (on all TDI's except the SPP version).
      Here are some specific concerns:
      1) Am I fooling myself thinking I can get extra depth with the TDI/SPP, particularly when it comes at the expense of a noisier threshold?
      2) Which coil(s) should I be using (choices I'm considering are 6"x8" Nugget Finder Sadie mono, 7"x14" NF mono, and 12" round White's 'Aussie' mono)?
      3) Should I flag the promising targets but double check with the Eqx 800 (and if so, should I use the 11" or 12"x15" coil on the 800)?  (Note, even if I choose this route I will likely at first dig, regardless of what the 800 says, just to get an idea of what is giving the signal and how deep the targets are.)
      Any other advice (from anyone) is appreciated.

      Today's hunt was in an old field inland about 5 miles . Short session. Did a grid on a section with lots of moss under a tree. Swept it with the 15x12 ,marked targets and switched to 6" to pinpoint. (9v dead in the 35) Would have switched to the small one anyway , still aching from yesterday....... Half a rivet , an old nail and a 3" piece of barbed wire.

      I did not think I would get a chance to get out this week, but since yesterday opened up for me, I decided to hit my favorite spot. I had a couple of ideas on how I would work this same area, but in reality, it required a bit of trial and error to get these results.  It was supposed to rain part of the day, so I figured I would use the Equinox for the morning. I wanted to get as close to the iron areas as possible, so I decided on the 6” coil. If the rain stopped, I would use the GPX with the 18” DD coil to get those deep dimes, in the other section of this spot. It worked, but I had to make a lot of adjustments to get each machine to do what I thought I wanted it to do. I think I have done all I can in this spot to get whatever remains within reach of my machines.  If there is more there, I do not know how to get to it. Surprises of the day were the Barber half, Barber dime, and a decent amount of silver. It took a lot of digging, more than just the number of targets shown.  The 18” coil is a brute to swing, Lucky you have to swing it very slow to get the good stuff. I am not sure where the next stop will be, but it probably will not be anything like this place has been. Who knows, Tony just fixed my AQ headphones and made me one of his as a spare, so maybe some gold hunting is in the cards. A relic hunt may be in the works for next week also, looking for Native artifacts. I have to hit the woods before the yellow jackets and ticks wake up. 🤬 As always, it's good to get out in the fresh air and enjoy the day!

      Does anyone know what the pots and push button on the circuit board of the Tesoro Lobo for?
