New Mexico/ Ground Condition/ Tesoro

Recommended Posts

...I've got a Tesoro Mohave coming in (after using the Minelab 305 last year, and the Tesoro SilverMax a few years back)(oh, and also a Teknetics EuroTec--arrggg)...the Mohave has a Ground Condition switch, and I'm curious about mineralization in southwest high desert (specifically central NM)--is it generally high or low mineralization, though I realize there's quite a varied geology in NM?  PS: chose the Mohave from Tesoro's lineup because I figured a new machine equals new and better circuitry, and ditto the Epsilon 7" coil.  What say?

Most of the U.S. Southwest would be considered moderate to high mineralization, but as with any huge area in reality it is all over the place. It just depends on where you are. I have gone from low mineral ground to high mineral ground in 50 feet. The Mojave is not exactly a nugget detector, but it should handle the ground where you are well enough.

Hello Steve...thanks for the information...I'd always considered a fixed ground circuit to be better than a manual adjust, and the high/low is one of the reasons I went for the Mohave...as for gold: no plan to prospect, even though there are sites nearby--but try finding an unfenced patch anywhere in the gold areas...some weekend coin shooting would be fine, and some off-road scanning near the old Camino Real will do it for me...Regards, Vincent

 I live in south central NM and have used the old Fisher 1266x, 1235x and 1236x2.  Also the Tesoro bandido ll umax, Vaquero, Cibola, Compadre and I have a Mojave on the way.  I can honestly say I have never had a problem with mineralization.  Maybe I'm doing something worog?

If you have never had a problem with mineralization how would it be said you are doing something wrong?

Hi Oldknifemaker...here's my experience...I'm now doing some detecting for an archaeologist who is contracting on private land. Specifically, he is searching for very early Spanish colonial evidence (metal). The archaeologist has been using a high end machine with a huge coil (biggest I've ever seen) successfully. He tells me that he uses a low ground setting. I'm using my Tesoro (7" coil) on high setting, because at low setting I'm digging every hot rock on the field and find it impossible to distinguish targets from rocks (the Pro tells me that volcanic surface rocks are to blame). But at low, I am really zeroing in on colonial metal--individual chain armor rings no larger than a smallish trout fishhook, at 5". I'm thinking that our machines are simply wired/tuned differently at the factory. This Mohave is such a pleasure to use--the sound-only allows me to keep my eyes on the ground and where I'm going (it's a huge field). Now here's a funny story for you: a native American I know wants me to teach him detecting with the Mohave so he could detect on the reservation!

Hi again Knife...I just checked Kellyco, and the machine the Pro has is a Makro Racer--one of those models with the huge coil...Regards, Vincent

Hi Vincent,  I agree that the detectors are more than likely wired/tuned differently.  My guess is that all manufacturers design and build circuits differently to perform the same function.  I'm sure most are proprietary and  and would bet that some are patented.  I received my  Mojave and took it out on my property to play with it and got a loud signal by my workshop.  I dug it and what a surprise.  It was a 12" aluminum pot.  Now why would that be buried on my property?  I live out in the  county on 2.5 acres and this was once a working cattle ranch.

      I found a Tesoro Silver Sabre Umax, the old one with the red pinpoint button. Has a 8" coil and looks to be in good shape 150.00 with a cheesy pinpointer. Any thoughts for making it a backseat toy?
      Update!
      I got it for 100 bucks and it's like brand new! My wife grabbed it and now it's hers. I put a fiber lower rod on it with a nylon coil bolt and it works great. She has a treasure pro and this is lighter for her and easier to operate. It's the small box one Steve like the modern silver uMax.But with an all metal pinpoint button and a threshold control. I'm trying to talk my sister out of her unused Compadre but for some reason it likes the closet at her house.

      I just havent been able to find the sweet spot on my vaquero ground balance the last couple times i used it cant seem to find that constant hum, either to negative or to positive, can someone help me out?
    • By DukeBoxer
      Today I picked up a Compadre at a great price to try out since I've read so many good things about Tesoros. I brought it home and played around with it a little in the yard. I think I've cleaned out my yard of good targets so I was just listening to the tone. Then walked into the garden against the house. I got a hit where I've been over multiple times before with an AT Pro and I bent down to check it out since it sounded like it was right on top. I moved a rock out of the way and probed around with the pinpointer and nothing. So I scanned the spot again and there was no beep and then I started scanning around thinking I moved whatever it was when I brushed away some dirt. Come to find out it was the rock itself that was making the detector beep. Here's the weird part...I had rolled the disc all the way up to max and it still beeped. I bent down and put the pinpointer against the rock and nothing. I went inside and grabbed my AT Pro and scanned the rock and again nothing. I thought it was weird and walked away. Then a little later I went to a park in my home town and was checking the playground with the mulch/woodchips. I found a dime and a zinc penny, both gave good repeatable tones and I had the disc set to the "N" in iron. Then I walked out of the playground and started checking around the edge in the normal dirt and was getting beeps all over the place. I turned disc up to max and again was getting beeps from rocks of the same type. These rocks are ignored by the AT Pro, the Garrett Pro Pointer AT and a Whites CoinMaster Pro that I had before
      I'm pretty sure these rocks are called basalt, they are brown on the outside and if you crack them open they are pretty solid and uniform and a blueish gray color in the center and a lighter ring around the outside. I'm also pretty sure they are high in iron and of volcanic origin (I learned about them years ago in grade school). I can upload a picture and a video of the Compadre hitting on them if anyone wants.
      I guess my question is for people using this machine, how do you deal with these type of rocks, do you learn the subtle nuances of the beep given off by these rocks compared to say a coin or junk or do you just try not to hunt in areas where they are concentrated? I honestly bought the machine to try and learn it and probably use it in playgrounds and tight junky areas. I don't see myself using it in fields or anywhere wide open since it has the 5.75" coil on it.

      At least on this day.  
      While I anxiously await the release of the Equinox and probably even more painfully, my position on the pre-order list... I am continuing to enjoy my Vaq Black.  
      I, and a hunting partner, decided to cover a sports field next to an early 40's elementary school a week ago.  I armed myself with my SE Pro, and he with his Deus... and we overlapped each others paths more than one time in the grass outfield of an old ballfield.  After a couple hours of hunting, a handful of clad and one wheat in my pocket, I made my way back to the car, and grabbed the Vaquero. 
      I am certain I covered the same ground we had both walked over in the hours before, but I was getting solid hits in the coin area and pocketing some more clad, including 2 pocket spills that included a quarter and a nickel among the coins.... which is interesting in itself (I believe the combination of low and high conductors changed the id, and one or both of us passed on the targets...).  
      I then came across a solid tone, and uncovered some beautiful silver.  :)  I know that one silver quarter is slim pickin's compared to some of the other finds posted across the forums... but for me.. it was a pretty amazing find.  Within 10 minutes, I snagged the silver ring as well.  A good day for the Vaq Black :)

      I've been in the hunt mode to find and acquire one of the rare 3X18  Delta 4 pin Hot Technology cleansweep coils for about 3 years. Finally got my hands on one.  These coils have been out of production for about a decade and they're about as rare as 'hen's teeth'.  Tesoro still makes the Cleansweep in the 5 pin Epsilon configuration but not the 4 pin Delta .  Mating this coil up to my Lobo Supertraq has provided me with some interesting observations.   Generally speaking it does cover a large swath of ground with each sweep, but the sweep speed has to be slowed down to say 1/2 to 2/3 of the speed of the stock 6x10 elliptical coil to get a good target response.   My best depth was a measured 5 inches on a quarter on edge.  It pinpoints fairly well off both the toe and the heel, but I do a full circle of the target to make sure the target is within my 6 inch cut plug.  The coil discriminates very well.       Now the interesting stuff.  First, it does not fully ground balance in the All metal mode. Pumping the coil down and up, it sounds off loud on the down push and does not respond on the up pull.  However, it is still functional in the AM mode, targets are still picked up clearly and the pinpoint function still works.   Both modes, All Metal and Discriminate achieve the same depth.  I ran the Sensitivity at a gain of 3, more gain didn't achieve any more depth.  In All Metal with a smooth threshold the coil ran stable and only responded to ground tracking and targets. In Silent Search Discriminate (setting of 3 1/2) the coil had at times a propensity to load up and give off erratic chatter, it also sounded off on 'bumping'.   I found the best way to run the coil was in AM and upon locating a target I would do a quick switch to Disc. to determine to dig or not to dig.  I will do some further testing but I believe I have found it's boundary limitations. A good coil, it just has some quirks.  I would imagine this would be more stable on a Vaquero.
