AQ Coil Questions
Jim in Idaho replied to stateguy's topic in First Texas - Bounty Hunter, Fisher & Teknetics
Thanks, Steve. I use a range of coils, but mostly either DF, or Folded Mono, both of which wouldn't be impacted much by this, but I also use a couple of NF coils, both of which are mono. Jim -
AQ Coil Questions
Jim in Idaho replied to stateguy's topic in First Texas - Bounty Hunter, Fisher & Teknetics
That's a great piece of info, Steve. I had no idea. Thanks! Perfectly explains my difficulties pinpointing with my SL. Jim -
Man, you're nailing it, Gary. Very nice! Right now I'm wishing i was down there...it's 5f here...LOL Jim

Very nice, Gary. Amazing how that bronze held up! Jim -
Sierra Super Pulse 350 Coil Questions
Jim in Idaho replied to TC-AZ's topic in White's Metal Detectors
TC, I only used it on a couple of outings, and there's no gold nuggets in my local area. I do remember thinking this coil has had little mention anywhere, and what I mostly read was people weren't very excited about it. So, my expectations were low. But, I quickly noticed I was finding a lot of old cartridges, and bullets. Some at depths beyond what I was accustomed to. Other than that, I don't have specifics. I know for a fact, I wouldn't sell it. Every time I notice it on the shelf I think "I need to get that out again". Jim -
Jim, that would be a very generous thing to do. I'm sure at least several people on this forum would be really grateful for that. Jim

Wow! Gary, I had wondered where you got off to. Think of you often. Really sorry to hear of your health issues, but tickled pink to see you have it beat. Looking forward to some beach relic, and treasure pics. I'm still using my modified SL I think I added the vernier control knobs after the last time we communicated. They are the nuts for easily setting, and fine adjusting, the GB, and threshold. Also, we still have one mod left to do on our SL's. I'll look that up, and send you a PM tonight. Seeing you post is making my day! Jim

Much better pics, Jim! Now if we can just get an engineer to look at that, and draw up a schematic for that board, we're gold! Many thanks! Jim

I've used mine on my TDI SL, and was pleasantly surprised how well it did. Jim -
First Impressions - Garrett Axiom Metal Detector
Jim in Idaho replied to Rob Allison's topic in Garrett Metal Detectors
Right, but it's already been down to zero at my place, and several nights in the single digits. Just sayin'. Jim -
California Gold Mining Getting Harder To Do
Jim in Idaho replied to GhostMiner's topic in Detector Prospector Forum
The truth of the matter in all this, sadly, is you only have the legal rights you have the financial means to defend. That's the real world we live in. Jim -
Need Goldmaster V-sat Advice
Jim in Idaho replied to cloudswimmer's topic in White's Metal Detectors
Probably. You might be able to run higher gain with the DD. Jim -
Need Goldmaster V-sat Advice
Jim in Idaho replied to cloudswimmer's topic in White's Metal Detectors
My understanding was that before the GMT, the Goldmasters were tuned to work with the concentric coils. Those "red", or "green" 6 x 10's were, I believe, concentrics. Where the ground allowed, they were very good. They even made the GMT better, in some instances. I've never used mine with a DD 6x10, though I found a great 2lb chunk of copper with it, using the 8x14DD. Jim -
Need Goldmaster V-sat Advice
Jim in Idaho replied to cloudswimmer's topic in White's Metal Detectors
The V-SAT's a great machine. I've got a GM2 and a GM3, and the 3 is still one of my favorite detectors. The 6 x 10 is good...all you really need, but the smaller coils would be better where the ground is hotter, as they "see" a smaller patch of soil, and thus mineralization. I've owned a GMT, and now own a 24K, but still don't feel handicapped using the GM3. The smaller coils also find use where the brush is heavy, or working around larger rocks in rough country. Jim -
Eric Foster Passed Away
Jim in Idaho replied to Carolina's topic in First Texas - Bounty Hunter, Fisher & Teknetics
Sad to hear this. A real loss to his family, and the detector community. My condolences to his family and personal friends. Jim -
Paul, please don't lose that added board. It would be nice if an engineer could figure out what that circuit is. Jim

TDI with Noise Reduction Mod
Jim in Idaho replied to Rick K - First Member's topic in White's Metal Detectors
Best thing is just buy an SL, do whatever of Reg's mods that weren't done at the factory, build a 16v battery pack, and that SL will equal the original TDI easily, with a very smooth threshold. Jim -
I put vernier dials on my SL. Made a HUGE difference in setting fine Ground Balance, and Threshold. I used to sell them, but am far too busy to monkey with them right now. Here's a link to the dials I used. If you want numbers, you have to make a disc, with numbers, to go on them. https://mgs4u.com/product/vernier-reduction-drive-14-inch-to-14-inch/ Jim

Are those subs insulated at all, Caleb? I'd imagine they are, or it would take a ton of battery power to keep it even moderately warm inside. Jim
-
The big box tdi stability mod required some additional circuitry (small circuit board) that is probably no longer available. I don't think Reg ever disclosed exactly what that circuit was. Jim

Massive New Crater Field Discovery In Wyoming
Jim in Idaho replied to jasong's topic in Metal Detecting For Meteorites
There's a huge one a bit north of me. The highest peaks in Idaho are on the rim of it. It's estimated to be 1,000 -500 ma. The Beaverhead crater. It was discovered late, too. Abstract The Beaverhead impact structure in southwestern Montana and eastern Idaho is an allochthonous* fragment of a large impact structure (~100-km diameter) that was transported some distance eastward during the Cretaceous Sevier orogeny. It is the first tectonic fragment of a large impact structure identified in the geologic record. The present evidence for impact consists of shatter cones, pseudotachylites and planar deformation features in quartz. The age of the impact is not well contrained but is estimated to be Neoproterozoic to Cambrian (1,000-500Ma). * allochthonous – found in a place other than where they and their constituents were formed -
Yup, does to me. Maybe that one coil has lower resistance than the SL circuit requires. That would allow more current to flow, raising the heat. That's good for you. It means you can charge your pack to 16v and enjoy the benefits, using the other coils. Good deal! I've found the Sadie, and 7 1/2DF to be very near equals. Actually slightly prefer the DF, but wouldn't feel handicapped with nothing but the Sadie in tight quarters. Jim
-
I ended up selling my MJ 5x9., Jeff. I just didn't think it was very good. I much prefer the DF 71/2, or 8 x 6 Sadie. I do like the MJ 8 x 12, however. Sorry to hear your detector gets hot with the 16v battery. it does make a difference. Jim
-
Jeff, what voltage are you charging the 4-cell pack to? It should be making a noticeable difference. Jim
