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.

Welcome to the forum Paul.  Nice to have you here.

I was thinking of heading to Danseys Pass for my XMAS break and contacted the campground there who said they'd let me run my sluice on their claim but unfortunately didn't end up making it, it just got too darn busy.

This forum here maybe of use too, there is a detector modification section with some very knowledgeable people who maybe able to help you

You'll have to sign up to be able to see or do anything.

This thread maybe of particular interest to you

I know what you mean about bumping into other detectorists, if it wasn't for KiwiJW who lives nearby to me I have only ever seen 3 other people with detectors, all on the same day and place oddly in my time in NZ which is now almost 10 years I think.

Hi phrunt , thanks for the welcome and the info threads, you're one of the reasons I joined up being a Kiwi and all.

      I was reading your post on Mding  going from N.Z. because of people not using real money any more, we don't want their dirty new money anyway, but there's still lot's of GOLD out there for guys like us to find (I hope). I still find plenty of pre-decimal coins at the old rugby field though. Got myself some little silver ones and a 1949 Half Crown before the rain came. Waiting on my rain cover then there's nothing stopping me, could stick my headlight on my beany as well.  We too were heading for Dansey Pass but didn't get there for the same reasons, maybe later on. 

      Got a question for you, but this could be the wrong place to ask, not sure being new here and all. Please set me straight if I'm doing wrong, but here's the ?

      Where in N.Z. can I have my MD repaired properly? I need work done, lost my pin point mode today and don't really want to ship it off to the U.S. to Tesoro if they're still there. I heard they were cutting back and maybe closing the doors altogether. I hope that don't happen, good machines is what they say especially the Lobo in the gold fields, that's why I got it.

      So who's a good Techy around here, in the know of MD's? Someone who knows their stuff not just any old jock with a screwdriver. I've had some bad luck with this Machine, first the coil plug which I fixed myself (proud of that) now this happens, hope it's not a Friday's machine.  

                                            Thanks in advance for all your help,

                                                                                                           Paul.

Hi Paul,

I can't be much help with your Lobo unfortunately, I've never had my hands on a Tesoro, however I remembered reading this thread on pinpoint problems with certain coils so maybe try another coil and see what happens if you have one.

I think it would be a massive gamble to sending your detector off to Tesoro for repair at the moment, the risk of never seeing it again are high seeing so many say they don't even answer phones, it appears they've gone bust.  It's probably better to buy another machine but I doubt you'd find one in NZ for sale.   A dealer I've used before in Brisbane Australia sells them however

I am betting you'd get a better price going direct rather than ebay to him.

I don't know of anyone in NZ capable of repairing it that knows enough about the detector.  Usually to repair such faults you'd need the schematic from the manufacturer which service agents get which you may possibly have from the image above and someone who understands the detector enough to work out the issue, a rare person I would imagine in NZ.  I think the schematic you have may not be the Lobo ST, here is a photo of its circuit board

Then there is this Russian site showing a Lobo circuit board which to me is certainly not a match but matches your schematic.  Was there a Lobo before the Lobo ST?  Even your board photos above don't match a Lobo ST

http://radiostudentmd.ru/english/articles.php?id=162

 If you decide to replace it this guide Steve's done is the real deal, honest opinions from someone who knows his stuff

If you can't sort out your Lobo issues you may discover more gold with a Gold Monster 1000, Gold Bug 2 or another higher frequency detector with the small gold we have in NZ with their higher frequencies.  Your Lobo is similar in frequency to my Gold Bug Pro and It wouldn't be my first choice for nugget detecting in NZ with our smaller gold nuggets, higher frequencies find the smaller guys a bit better as long as you're in shallow bedrock locations where gold is near the surface.

Well done on your coil plug fix!! 🙂

Simon

There was an earlier version of the Lobo that has a manual GB as opposed to the tracking on the newer version.  I believe the manual GB is the schematic that you can find online.

Hi Simon, Yes that schematic and other pictures are from that Russian site. I have been typing to him through E-Bay trying to get one of his completed builds, box and all. I did buy a PCB from him in hopes I could find someone to assemble it for me because I lost out on the built PCB he had for sale.

However after talking with him again I find out he will be building some more assembled boards and even an under elbow unit mounted in the box with battery compartment. That's the unit I really wanted to get. 

I was going to run both on the same machine one at a time of course, to see what kind of performance it would give me. I do hope he finishes it soon.  Yes Lobo did have an early model and even some under different names, like the Ozzy one the Dingo and for some other retail stores without the Tesoro Brand name on them.

Hopefully you can get it sorted then, it seems a lot of owners of Tesoro's really treasure them so they must be pretty good units once you learn their language.

I think your just trying to make me feel better by saying these nice things about the Lobo.

That might work, but for now I'm still having buyers remorse. Just looking at my empty wallet and wiping the tears away. Thanks any how.

I believe that circuit board is for the original Lobo.  According to Dave Johnson who designed the LST, the only thing that the Supertrac and the original share is the name Lobo.

      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?

      Hello, Live on the Kenai Peninsula and bought a Tesoro Lobo st last winter in Arizona, the snow is going away time to learn the machine, Anthing I should know about the soil up here and any special mode to use up here, Looking for everything from coins to nuggets, Thanks

      I have been using the 9x8 concentric coil mostly for park hunting and trashy areas and wondering how good the 12x10 wide scan coil is on depth and small targets or would I be better off with a Nel Thunder or something similar? I find the 9x8 a little tedious on big fields. 
      Thinking of getting that coil along with a lower pole and other parts as back up since Tesoro seems to have evaporated.
