  1. Recently my Tejon seems to be extra sensitive to EMI and I get a waiver or flutter in the threshold. Is there a way to tune or fix that? Not sure if something is failing or if it is just out of tune. Thanks
  2. 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.
  3. I have found that my Vaquero is a good honest all around detector that fits much of my detecting style and needs. I would like to do the high tone audio mod. Contacted Keith Wills and he does not do this mod. Is there anyone currently doing this upgrade?
  4. I need a little help here in understanding the primary discrimination knob. Here is my observation. 8X9 coil, Using a lead pellet as a test target, buried 3", when placed in All Metal the target sounds off loud and clear. When switched to the discriminate mode, knob far left (zero discrim,) I don't receive any signal. I would think that at the lowest discriminate setting I should be getting a signal from iron on up. Is it possible the internal discriminate circuit out of adjustment?
  5. I recently had the pleasant surprise of a mint condition Tesoro ‘Outlaw’ metal detector, minus coils, showing up at my doorstep as a gift from a very generous enthusiast and forum friend. It is an attractive metal detector and after spending a little time with it, I find it a very interesting detector, operational wise, as well. It has three operational modes; a motion all-metal auto tune mode, a non-motion all metal mode, and a silent search discrimination mode, all accessed via a three-position switch. It also includes a manual ground balance control dial that affects all the operating modes, a threshold control dial, a on/off + sensitivity control dial, a discrimination control dial, and in the center below the speaker louvers is a dual layer push button that servers both as a pinpoint and a retune button. Seems all very straight forward at first glance, until you discover its secret: The Tesoro Outlaw is a true, threshold based, metal detector. The threshold setting affects every aspect of the detector. The good news is the threshold setting is a set and forget control. Set it to where it gives the faintest hum and leave it alone. For me that is approximately the 1 o: clock position. And that brings us to the center Red Button. That little red push button in the center of the Outlaws face plate is the most important control on the detector. It is imperative that after every setting change that you make to the detector settings that you press and hold that red button and hear the threshold return. I mean after EVERY and ANY adjustment to the detector settings, no matter what the change is. If you change the disc setting, you press and hold the button until the threshold returns. If you change the Sensitivity setting, you press and hold the red button until the threshold returns. If you change threshold settings, if you change operating modes, after you ground balance, you have to press and hold the red button until you hear the threshold return. Takes about a second, maybe a second and a half for the threshold to return. No big deal once you understand it but it has to be done. If you don’t return to threshold after every and any operational setting changes the detector will be working at reduced performance/reduced depth, as if the threshold had been set somewhere below the audible hum, which will affect your depth. That is the way it operates. Once you figure that out you are golden. There are two all metal modes. The far-left switch position says ‘AUTO’. This is the motion all-metal mode with auto threshold retune. This is the operational mode that you need to be in for ground balancing. The all metal gain is preset. Sensitivity is controlled via the threshold setting. The threshold auto retune speed is perfectly acceptable for the majority of ground minerals. Might be a little too slow for really bad ground but for most of us it is fine. The middle switch position is the non-motion all metal mode. You control the threshold drift via the red button retune. Again, the all metal gain is preset. Sensitivity is controlled via the threshold setting. Ground balance affects depth performance for high conductors in all operating modes. Too far positive (clockwise) and you will severely impact high conductor response. However, the ground balance does not go all the way to salt so low conductors are not affected by a maximum negative (counterclockwise) setting. Yes….if you do not intend to use the all metal modes you can Power Balance in Disc mode. Yes….if you do not intend to use the all metal modes you can super tune the Threshold. The Discrimination mode is the far-right switch position. The Sensitivity control only affects this operating mode. The Threshold setting affects this operating mode. Ground balance settings affect this operating mode. Assuming you have your Threshold setting where you want it, and are ground balanced to an acceptable point, then you can further increase your sensitivity with the Sensitivity control. Discrimination control is classic Tesoro. I think the Disc range is ED120 or there abouts. It is easy to max the disc and just hunt high conductors and it is easy to disc out most small foil and hunt nickels upwards without losing a lot of depth due to the disc setting. I put the Cleansweep coil on it this past weekend and hunted recent drops and found it good on both high and low conductors. The Cleansweep is a fairly shallow coil….5” to 6” tops in Disc mode. Maybe 3” more in all metal modes. I was happy with its performance on both low and high conductors as a 10.6 kHz unit. I was happy that it seemed pretty EMI resistant. Ground balancing in the Auto tune mode is pretty straight forward, except you have go a bit slower on the coil pumps than you might normally be use to as you have to let the threshold retune between pumps, again about a second, second and a half. It’s a neat detector. I’ve never used anything quite like it before. HH Mike
  6. Got a call from my Sister yesterday afternoon. "I'm at Goodwill and they have a metal detector here for $7.50. You want it?" "Sure, what is it?" "A Tesoro Lobo" "You bet" "OK, I'll bring it over later". It has a broken arm cuff, but other than that it's really clean. Very Good to excellent condition. Not all my "Treasure Hunting" is done with a detector. Just wanted to share.
  7. These past few weeks, been using various analog models at an old farmstead. Although we’ve hit this area numerous times, hardly anything good surfaces but it’s a fun site to hunt and a good site to test equipment. Between the seven Tesoro models I’ve been using here these past few week’s, the Cortes was probably the best of the bunch and thats with using the 12”x10” DD coil and with full sensitivity. The 12”x10” spoked concentric coil was okay with a lower sensitivity, but it suffered some stability with increasing sens and that’s due to our West Coast inland soil. So, pretty much stuck with the larger widescan. Second best was the Lobo, Although it lacked depth it was great in areas thick with iron. Next, The Outlaw and modified Mohave ran equal, good depth with using the 12”x10” DD. The Mojave has a manual GB, which is needed for my soil. The Pantera did well, but tough soil prevented the extra depth needed. The Deleon just couldn’t get rid of the falsing, even with the large DD Deleon can’t handle our soil with high sensitivity. The Golden uMax did okay, but our soil is tough on the Golden. The 12”x10” DD improved depth with all these models with the exception of 4-pin Lobo, using stock coils with the other models in my soil were useless. The larger widescan coil is definitely deeper, eliminates most if not all ground noise, and still very sensitive to smaller targets. My favorite out of this Tesoro bunch is now the Cortes, for farm land hunting and definitely running the 12”x10” DD. One 1951 silver dime surfaced, one wheat penny and 1959 copper penny. Two musket 1/2 balls, few saddle snaps. Site has potential, We’ve pulled numerous seated coin’s, Couple of Bust and one gold coin from here on previous hunts. Going back today, this round will use a Teknetics Mark III, Compass CoinScanner Pro II, GoldScanner Pro and a Whites 5900 Di-Pro. Can’t wait, older technology makes the hunt more challenging and fun.

  8. Hello everyone, I have just joined up and this is my very first post. I'm surprised to see fellow detectorists here from New Zealand. I've been here in N.Z. for almost 12 years now and only bumped into one other detectorist just a little while ago, some newbie from Christchurch going back home after his first trip to Kyeburn Diggings up Dansey's Pass. Some older dude with his new Gold Monster 1000, he stopped off at the beach here in Timaru for a snack and his afternoon nap. No luck for him this time and he was complaining about all the metal the old time miners chucked about there. That's along drive to about 2.5 Hrs one way. We were just heading home after hanging out there for the afternoon, when he saw us just after testing out my wife's new BH Commando TK4. So we had a little bit of a tail-gate meeting with him. He wanted to showed us his GM 1000, it was nice to have a look at one up close and I took it for a bit of spin in the dunes. Anyway I'm not here to chat about new acquaintances, got much more important stuff to talk about. I would like to Hyper-Tune or Super-Tune my Lobo ST and need some help with it. I Was thinking about putting on an external ground balance potentiometer to get some more depth, but first I need to know how it all works. Because my wife and I are Newbie's too and I'm trying to teach myself, my beautiful and talented assistant the "wife" all the ropes about MDing. So if anyone can help in anyway it would be very much appreciated. A German guy did that to his Lobo and he seams to be happy with his mod I think his name is mschahl and another guy Keith they both seem to very knowledgeable about the Lobo ST. I would love to here about what is and isn't, the up and down's, the in's and out's and what mod's I could do with these two MD's the Lobo and BH TK4. Also I could get a new PCB for the Lobo and put it in a build box like the one shown or drop it straight into the Lobo but don't know where or who could build it for me. This way I can take out the factory one to keep for a back-up incase anything goes wrong with my build. Thanks' in advance for all your help and it's nice to be here, I don't feel so lost now. Paul.
  9. I found this nice tesoro compadre at the local goodwill today for less than $20. I couldn't resist buying it. Took it home and put in a new battery and it works great. it must be an older one because it has a metal coil screw.
  10. I've always liked the Tesoro Cortes. I like the design intent. I like the way it looks. I like the Sum mode with the audio tones. I like the graph. I like the Target ID range. I like pretty much everything about it except the single tone hunt audio in Disc mode and the overshoot null in the non-motion all metal sometimes gives me a fit. I've had six of them over the years and I usually part with them mostly due to the single tone hunt audio. But I get nostalgic after a while and end up getting another one every now and them....which is what has just happened. I saw one for sale and started looking at it again but didn't jump. Then a NIB unit came up for sale at a very good price and I couldn't help myself and jumped. Welcome home number seven. HA. I think I will put the Cleansweep coil on it and just hunt athletic fields with it where beep dig single tone is ok and all I really care about is ground coverage or places that I've already cleaned out and just want to run through for recent drops. Hope to hunt it next weekend and share thoughts and results. Wife is probably going to wack me, though. Only been two months since the last new purchase. HH Mike Tesoro Cortes Data & Reviews
  11. I’ve been doing some freshwater hunting with the Excalibur lately but I’m finding that the old girl nulls quite a bit due to the lake floor being quite mineralised...it is a clay base. I can turn the Sens into Auto but that really dumbs the unit down and depth really suffers. I have been thinking of getting the Tiger Shark but not sure if the GB will be effective enough and whether it can handle the minerals. The Excalibur in PP is quite effective but there is too much iron junk to contend with. Any thoughts out there....... Thanks Tony
  12. One popped up on eBay just now - couldn’t resist - Buy it Now - I did No coil. If I understand correctly it takes standard 4 pin coils for the Lobo super trac and similar. Have to figure out what coil to get for it. This will be my third one - Probably made enough off the first two to pay for it - but out of respect for Dave Johnson - who designed it and pronounced it to be his favorite design - I guess I’ll keep this one.

  13. OK. I have a nice little Compadre with the 5.75" coil. I also have a Vaquero with the 11*8 coil. Will I benefit having a Concentric coil for my Vaquero or would it be a little bit redundant? And what coil would you get, as the 5.75" concentric is pretty much unobtainable, for the Vaquero if replacing the coil? Thanks
  14. Is the Delta 4 pin connector proprietary or is it something someone sells somewheres? Looking into building a coil for my Tejon and if that goes well will use it on a Lobo mod. Thanks
  15. I’m looking for internal pics of the power box. I have a few wires that broke loose from circuit board. Also the 2 wires coming from the battery compartment. Thank you
  16. I like my little Compadre. While it looks overly simplistic its actually a pretty decent metal detector with a full range disc circuit. I bought it for my wife but then I modded it with a connector so I could switch out coils and now I run my Cleansweep coil on it. I just set the disc to accept my lowest reading ring and go beep and dig with it. Since I'm only hunting the top 5 inches of dirt or woodchips I don't need a manual ground balance and the sensitivity setting on mine is just right for my EMI and depth requirements. The 12 kHz operating frequency combined with the full range disc is plenty sensitive to the targets I'm after. And if you like to tinker, its a cheap detector to mod with. I like it and can recommend it to any and all. HH Mike
  17. Winning bid of $200! That's got to be a deal! I paid like $448 the first time I had one.
  18. The Tesoro Pantera is a VLF discriminating metal detector that was produced around 1990 by Tesoro Electronics. It had a cult following due to its proficiency in extracting non-ferrous targets from dense ferrous trash. Information on it is rare so I am reproducing the material from the catalog page below. Instruction Manual at tesoro.com GENERAL DESCRIPTION The Pantera is a high performance VLF metal detector which is capable of rejecting ground mineralization and buried metallic trash simultaneously. It includes Notch Discrimination so that most common pull tabs can be rejected without losing nickels and small gold rings, or so that only a particular band of desired targets will be detected. Notch Tone Target ID provides a low tone for targets below the Notch Level setting, and a higher tone for targets above the Notch Level setting. Design emphasis was placed on performance and ease of use, while minimizing or eliminating those troublesome adjustments that could cause a loss of performance if not used properly. The Silent Search Discriminate Mode is based on motion, which means that the search coil must be moving slightly to detect a target. The motion required is so slight that pin-pointing is possible in this mode, however a No Motion pin-point mode is included, which with the 8 inch open center search coil makes pin-pointing a very simple task. A Ten Turn Ground Adjust control is used, which allows the detector to be adjusted to virtually any type soil. This control allows the operator to get the absolute maximum performance from this detector. The unit is furnished with an 8 inch open center concentric search coil. We feel that this coil will provide excellent performance in most situations. The open center greatly simplifies pin-pointing. The detector can be used as a pole mounted arm rest unit, or as a body mount unit. It can be converted easily without tools.

  19. Hi All, I am looking to get a Tesoro very soon as I had one years ago (Laser Scout - UK version) but I'm torn between a Tesoro Cibola and Vanquero. Also are these machines good on dry beaches also how about wet sand? Is the C better than the V and if anyone can help? I'm hoping some members here may have some information as to help me on this subject.
  20. I read a tip on super tuning the Tesoro Tejon and didn't see any difference in depth at all. In the tip they said to do an regular gb with sensitivity @ 10, then turn the GB + 1/4 turn (approx. 8.33 on a vdi with scale of 100), then turn the sensitivity back just until the machine stabilizes. Did some quick depth tests and found id made no difference at all. I tried similar technique on my AT Pro and had a loss in depth of approx. 1". Am I missing something here? Is super tuning some sort of myth?
  21. Got a used Tesoro LOBO, but with or without coil, it just screams when I turn it on. Adjusting threshold no help. Any ideas, or anyone need it for parts? Thanks, Jeff in AZ
  22. Hello new here and to detecting. I bought a new Lobo st in 2004/2005 played with it a bit and pulled the batts and put it away for a few years. i didnt have much luck with it . i have a gold piece 24k about .51 grams and .400 long .200 wide and .050 thick, how deep should i be able to detect this piece. ive got several silver dimes and quarters older pennys going back to 1890s. im setting up a test field with the coins in zip lock bags. and rope markers added some junk and nails as well . should i be able to detect a 1971 penny at 6 inches in any mode? im getting nothing, and i see videos at 8 ,10 ,12 inches and nothing on the gold at 3 inches, could there be something wrong with the detector?
  23. I found this site that has posted all of the Tesoro Brochures for each model. Great walk down memory lane for those who love their Tesoros. https://www.treasurelinx.com/tesoro.html
  24. I’m interested in finding a used Tejon. The Tesoro’s remind me of the Sovereign GT in some ways.
  25. I know it needs to be in the classifieds and maybe thats where i will put it, but thought id ask what a gently used tesoro vaquero in perfect working order would sell for?
