  1. is there much difference between a GP extreme and the GP 3500 ?. I would like it to look for coins and if possible also for the beach
  2. I have an older Minelab GP Extreme. After a theft at my place, I found that it's battery charger was missing. Does anyone know where I can get another battery charger for it?

  5. I took a Fatshark battery pack that holds two 18650 li-ion cells and fed it into a buck converter adjusted to 6.86V output and used it to power my GP Extreme. I'm testing out a (TDI) Beach Hog coil at the beach. I have a Barrie Johnson Nuggettfinder MKII that has its own speaker/amp as well as speaker/phones volume controls. The buck converter has less than a volt dropout so it has a reasonable life of about an hour and a half. I did run into a problem though - if the coil got too near my scoop the detector overloaded. Something, the audio amp, the detector, I don't know which, overloaded and went into a low frequency oscillation. I thought I had fried the detector inputs but I shut everything down, waited a bit, and repowered and everything was fine. I can't duplicate the issue using an input signal from a signal generator into the Nuggettfinder - which has me scared now. It happened twice in the latter part of the battery life so maybe this is a factor? Is the GP Extreme designed to take overloads from large metal or is it at risk of frying? I bought mine with fried inputs and fixed it - don't want to do that again. I may move to a buck boost converter, put a 2S battery management circuit on the pack, and use larger 26650 cells which would keep the voltage stable and last longer.
  6. Took the plunge and sold a ring and bought a SD2200 with a few coils. Just for a bit of fun alongside my Equinox 800. Any ideas how I can go about salt-proofing the control box? I'd like to be able to access the buttons and knobs if I can. Thanks
  7. G'day, just new to this forum. Wondering everyones opinions on a 2200D for beach detecting on dry or eroded sand banks? I have a few spots in mind which a pulse induction machine would be handy on spots my mates CTX can't reach. Of course I'd have to waterproof the machine but as a general machine for depth would it handle alright on these areas? Anyone here use the machine for beaches regularly? It'll be my first pulse machine, I'm a long-time user of the Equinox 600 and 800. Cost isn't an issue, I'm just getting bored and limited in parks. I found one at a decent price with a few DD coils. Would I just be wasting my time and money? The spot I have in mind is a long strip of beach where I've found a bit of silver and military relics in the past, and I know of someone who's found a half sov and someone else who's found a cartwheel penny there . I've looked in to a Whites TDI machine but seems like no one here sells them 😞 Cheers!
  8. As the title says. I would like to discuss the current status 3500 brings compared to its digital Brothers 4000,4500, 4800, 5000. I am sure that we all enjoy and appreciate the older Tech, but does it have an equal footing against the new generation. Simply put can it hold its own against a 4500 or 5000. I don't except it to equal to say the 5000, does it give said units a run for there money, as the saying goes. I think we all pretty much know that the newest Gadget or Gizmo doesn't always equate to True massive Performance differences in the field. Example being the 4500 against the 5000. The differences are so minimal in true real world Performance that one could easily justify not going to a 5000. This is the type meaning I am asking. Such as fine gold, how low can it go lol. Deep gold, how deep and how big does it need to pick it up at that depth. We have a lot of great swingers on this forum, always willing to discuss these conversations. Perhaps this might help others in the long run. Things to consider 3500 has been discontinued. But so was the 4500 to a certain extent at a certain point in time, no longer the case of course. Did the 3500 excel at a certain thing? Kind of like the gold bug analog unit that finds specks of gold. There by still relevant in today's Tech.
  9. Hello to all i have my eyes on a SD2200D are the eve coils compatible with the SD ,or it needs to be modified in Ballarat,i dont think anyone will modify them in the UK 🙂 Also the last one i saw going on th eBay of thieves went for 295 british pounds how much will you pay max??? Thanks for your input RR
  10. So today I decided to take my old SD2200D coupled to my 17x10 coiltek mini ufo coil up a local creek that I has been very heavily detected. I also took along my Fisher gold bug with its 5 inch coil. My plan was to walk right up this creek detecting with the SD on the way up and then the gold bug on the way down. We have not had any decent flooding for a looooong time so any exposed bedrock has seen multiple coils by now. My plan was to target deeper areas with the Sd and then try to find some missed crumbs with the gold bug. So long story short I got a 0.6g and a 1.2g piece. Both were on the edge of bedrock areas where deeper gravels start. Having not had the sd and it's selection of large coils that long I was surprised at the comparatively small pieces it was able to detect.(when compared to the massive coil). I ran out of time to use the gold bug much but I've used it a lot in this area before so wasn't expecting much. Thanks for looking!

  12. The Minelab SD2200D was the first Minelab PI model I really used a lot. I tripped over this old photo from 2000 of me and my SD2200D taken by Jeff Reed. I am pointing at the location where I found a nice 8 pennyweight (20 pennyweight per ounce) nugget. This was high in the Wrangell Mountains of Alaska. Steve's points to where nugget was found

  14. I recently picked up a used SD 2100 on craigslist for next to nothing. When I power it on, the audio clips then settles down to a stable threshold . It also clips on a strong signal response. Is this normal ? Thank's to all who reply
  15. What would the difference be on mineralized rocks and hot bedrock between these two detectors? Took out my 3k and had a hard time detecting due to these two factors. Hoping a new 7k would solve that issue. Thanks.
  16. I just bought on eBay this coil minelab "super goldsearch 18". I bought it as a project for the tdi. I showed it to a friend with many years in the hobby, he told me that he had seen it many years ago and that he remembers it for the "beautiful design". It looks like the lid of a garbage can. According to when it was manufactured, it was a very expensive coil, designeg for the SD, but it has no more information. Does anyone know anything about this coil?
  17. Anyone know where I might get this part? Thanks. The hand hold broke off.
  18. Me gustaría saber cuál es un precio razonable para el GP 3500 de Minelab. Supuestamente está obsoleto ya que hay 4 nuevos modelos. Gracias
  19. Hi guys, Long story short, i was given an unused sd2200d today! Amazing generosity from a friend. My mate remembered his father had bought the 'best' detector some 15 odd years ago and was often talking about finding gold nuggets! Unfortunately he passed away before realising this dream - in fact apart from turning the machine on to check it worked, it hasn't been used. I have some fun research to do. While having found gold on several occasions i have only been in this game for a couple of years so while the reputation of the 2200 hasn't eluded me I am certainly unfamiliar with the machine. I have no intention of selling it. Infact I would like to find some gold with it to drop off to my mate & his family. I did wonder when or if a detector becomes a collectable though and maybe shouldn't be used - as this 2200 is like an un opened toy, not a scratch on it! I own a 7000, my wife has a 5000....so i wonder if there is a unique occassion where the 2200d might shine? I will research a bit to find out if any of the new generation NF or elite coils can be used on this so i can interchange with the ones on the 5000. Anyhoo I thought i would share this story and the gift...hope it brings back memories for many:)
  20. My Minelab SD2100 needs to be checked out. It will suddenly go into overload three times in a row, just as if you were swinging over your pick, and then go back to running normal. It won't handle EMI's any more no matter what I do. The control box has never been opened up to my knowledge but I'm not the first owner. The problem is constant with the three coils I've tried and with the power cord. It has happened in different areas. I've not shaken the box to see if there is a loose wire inside. I can only say that it's gotten bad enough to be unusable. I'm wondering if it's a problem with the tuning circuit as the tuning screws do nothing when trying to tune out EMI's. Minelab will not work on it so I need suggestions for a repair station I can send it too. This 2100 has found a lot of gold and isn't ready for the dump yet! Any suggestions would be appreciated. Thanks! Stickwhipper
  21. So, for strictly nugget hunting which one would you say is the better choice, the Garrett Infinium LS or the Minelab SD2100V2 with Doc's Gold Screamer power pack?
  22. Hello all,I'm a longtime lurker first post. I prospect mainly in the Mohave Mountains behind LHC AZ. I'm currently using a F19 and am somewhat successful on the shallow small stuff. I'm going to upgrade from or compliment to my F19 with a PI. My budget is around 1k. I have a chance to pick up a gently used sd2200 for $800. I can't help wonder if I'm better off with that or a TDI sl. Any thoughts or advice is appreciated. Thanks!
  23. This is more of a complaint issue post than anything else. My first GP handle lasted me 2 years or more before it gave wY and broke. The new one I have I bought about 6 months ago and just left be dead in the scrub with no paddle. My observation is Minelab is cutting costs and producing the new handles with a softer grade plastic and for people like myself who hunt daily it's not adequate. I am going to send these pictures to Minelab so they are aware that softer plastics Just don't cut the mustard! Anyone else had the same issue ?
  24. I am looking for a amp for my 3000. I can find Doc's gold screamer and a B&Z Booster. Are these my only two options? Thanks for an input.
