  1. Over ten years ago I was pushing pretty hard on the idea that high power pulse induction detectors would eventually find use for more than just nugget detecting. Relic hunters in bad ground seemed a particularly obvious situation where PI detectors could pick up where the VLFs left off. Daniel TN just made a great post over at Dankowski’s about the shift from VLF to PI, and how the PI use progressed up the power ladder from Garrett Infinium to White’s TDI to Minelab GPX. I ended up calling this Steve’s Law Of Target Depletion. The basic premise is that if high value targets exist, people will start with discriminating VLF detectors and dig the easy targets. However, knowing good finds remain, over time more trash is dug and more powerful detectors used. As long as any chance of a good find remains, this progression will ultimately deplete a good location of all targets, good and bad. Prospectors see this all the time. A location will start with trash and gold. VLFs cherry pick out the easy stuff. Then the “dig it all” troops go to work. Sooner or later you get to where just finding a target, any target, gets to be a challenge. Yet as long as a single target remains, good finds still might happen. If nothing else the trash can hide good targets lurking below, and so even trash remaining can be a good sign. You can never call a place detected out until no targets at all remain in the ground that can be found. And even then, a newer, more powerful detector may make the place come to life again, at least for a time.
  2. Hi guys new to the forum from down under. I can see there is a wealth of info on here and looking forward to taking it all in. I recently hired a Gpz7000 and its an amazing machine however out of my budget (for now). While on that trip I was having major problems keep the machine quite. So I was advise of looking up Lunks settings for the Z. WOW this turn the trip around and picked up half a dozen bits of yella. However I have now come into GPX4500 and I am wondering if there are Lunks settings similar to that for the 4500. I have had a search but cant see anything as yet. Hoping someone can point me in the right direction. Thanks MATE!!!!
  3. Editors Note: This topic was split from the following thread - http://www.detectorprospector.com/forum/topic/3923-semi-auto-gpz-ground-balance/ I believe there is a lot of reasons of trying to turn GPX into a GPZ. They wont be never the same thing since they are in different technology . But anyone would like to walk around with an more affordable machine that could pack a punch of the " GREATEST". Im someone who started metal detecting and someday looking to upgrade to a heavier and more powerful machine. So after reading the pro and cons of each one i would pick a GPX over GPZ even if i found a Pound of Gold. -Lightest machine? GPX wins even with a larger coil. -Coils price and more coil options? GPX takes that. -immune to the hottest of ground? GPX i guess wins this since is a PI. Dont know where that ground exist but i know is out there. Okay so i have seen running a GPX with one of the newer coils could match the performace on depth on sub-gram nuggets and up. Now the GPZ would clearly stand out on tiny, spongy and specimen gold. But wouldnt you have enough money left to even buy a SDC 2300? I just dont see the reason of boasting a machine for ability to pick up super tiny gold when you need to pay so much for it. That headline for me fits more a GM1000 since its a way less expensive machine.
  4. Guys (and gals), there's an area here in Rye Patch that's under a high voltage power line that everyone with their 7000's and 2300's won't bother detecting due to the obvious issues but I recall people being able to run a DD in, I think it was cancel mode or something like that. Granted you'll lose depth but where they (and my 7000 can't go), I know there's gold there as I've seen BIG gold from a dozer push near by and was thinking of swining my GPX 5000 at. I have a few double d's in my bag of tricks here (glad I brought them) and am thinking about giving it a go. Any tips from those who've attempted this? Do you run in DD, Mono or Cancel? Sadly I don't have a Nugget Finder XP coil which I believe was intended for this purpose. Thanks all. Jen

  6. Monster Coil Jam

    Sorry about the title, I couldn't help myself with all the monster talk . This video is a bit of detector vs big coil comparison on a decent sized bit of trash (unfortunately).
  7. Coils For Caliche

    I had my first experience with caliche recently...I was wondering if anyone has advice on which coils work well on caliche covered nuggets. I plan to buy a 9x14 evolution soon, but don't know if that will be better in this regard. I was swinging an advantage 12" RM and managed to get one, but thought there could have been some I may not have heard. I use a goldscreamer and it blasts on the tiniest of targets so I think there may be something special about nuggets with caliche. Any experience you can share is appreciated.
  8. Hello, This was posted in the Find's forum as well but no answer yet. So I am planning on getting a 18 or 15" DD coil for my GPX 5000 for relic hunting. I am looking at ML and Detech coils. I am unsure if I should go ahead and get the ML 18" DD or rather the Detech one, or maybe even the 15" Spiral DD by Detech. Which one gives more depth on relics? Which one is more quiet? Any suggestions? Thanks FschJg
  9. Just recently we were detecting (all experienced detectorist) in the grasslands of California, with two GPZ's, one had the stock 14" coil and the other had the 19" coil and two GPX's one had the 17x13 Evo and the other had the Minelab 12x15. Towards the end of the day, we decided to perform a test. We buried about a 9mm slug 14" deep. I went over the target with my GPZ, HY, Normal, Sen 15, Smoothing Off, and barely heard the target. Same settings with the 19" but much better results. Heard the target about three inches above the ground. Next, the GPX with the Evo coil in Sharp, General, don't remember the gain but a smooth threshold with the gold screamer, and no signal. The next detector is the one that is really giving me heart burn, the GPX with the 12x15 commander in Sensitive Extra, General, don't remember the gain but a smooth threshold with the stock battery. It gave an obvious signal about 5 inches above the ground. I could not believe how loud of a target response this stock GPX gave. After hearing the results from the GPX, I increased my Sensitiviy to 20, but there was too much ground noise to hear a target. I also tried different ground and gold modes with the GPZ, but nothing compared to that GPX. I wish we had more time to really investigate, but we were all tired, and the sun had already set behind the mountain. Is this just one of those scenarios that we must except and move on, or is there some credibility here??? Has anyone done similar tests or can give some suggestions? Still scratching my head, Brian.
  10. how do i find out the birth day of my 4500? Thanks for the help.
  11. when useing a DD coil on GPX 4500 do i need to flip toggle to DD?
  12. I have a ML GPX 4500 and want to buy a control box cover that has a battery pocket. So, I need a shorter power cord...any idea where to get one (and ensure it meets specs)?? And, any suggestions on the best headphones? ...Killer Bee Wasp?
  13. As a total newbie, the more I read the more confused I become. I was leaning towards a 2300 as a first machine to use when I move back to AZ. But I was looking at the 4500 and 5000 as the price where I am are all within 100 bucks of each other. Makes for a tough choice........BUT then I keep reading about the GPZ and the size and depth increases it affords and I think that is the machine I will ultimately want anyway. I am new to the detecting(read zero experience since the 80's), but not to prospecting. Would I be getting over my head going straight to the GPZ? I am not talking about the price as much as I want to know if as a first piece of equipment is it too much? Do I need to work my way up the ranks before I get the big dog? I do not want to buy and then sell a 2300 or a 5000 or both only to arrive at the 7000 as an end game machine anyway. So if I bite the bullet and skip the retirement watch..... I defer to the experts.
  14. Hi all, I'm ready to buy my first detector and have narrowed the choice down to two. Mainly based on price but some advice could help point me in the right direction. My choices are the GPX 4500 & SDC 2300, within $100 of each other. Most of my hunting will be in the Golden Triangle of central Victoria, Australia. The GPX seems to be more versatile but the SDC appears to be easier to master. It appears both will find gold in the right hands so I suppose my quandary revolves around which one will give me the broadest chance to find gold in quantity and size. Cheers in advance, Benny.
  15. Minelab SDC Vs GPX Vs GPZ

    Great Treasure Talk blog by Nenad Lonic at http://www.minelab.com/go-minelabbing/treasure-talk/comparing-minelab-s-sdc-gpx-gpz-detectors comparing and contrasting the Minelab SDC 2300, GPX 5000, and GPZ 7000.
  16. Above is a quote from Jasong, from another thread that hits the nail on the head. Somewhat a forbidden topic on OZ forums, which I guess says a lot about social media. This matter has been touched on by others when speaking about the "new age" coils on the Xs in other threads. While I`m a confirmed and dedicated Z user, I recognise because I`ve experienced the ability of these coils and how they have closed the gap( in the field on undisturbed gold), plus in some cases exceeded the Zs ability. Saying that I`ve also experienced more cases where the Z exceeds the Xs ability. But it is interesting and really says it all about the dominance of ML, their only true competition to their latest serious gold detector is their model it replaced. This has been so for how many years? What are the other detector manufacturers doing? And why is it sort of "taboo" to post about this subject?
  17. I would like some opinions on what my next coil selection should be for my GPX 5000. I have my Vlf unit (Eureka Gold) with 3 coils to cover the smaller gold. Presently for the 5000 I have a 8" commander mono, 11" commander DD, 11" commander mono and a 16" Nuggetfinder Mono Advantage and I would like at least one more coil. I'm thinking to maybe get an even larger mono. Maybe the 22" Coiltek Goldstalker mono, Or the New Coiltek 18" round Mono Elite. But the Coiltek 24X14 goldstalker sounds interesting. Then of course there is the Nugget finder 25" mono Advantage but it's much more expensive than any of the others. On the smaller side there is the 14X9 Blitz said to be developed for the 5000. So what would you all think I should buy?
  18. Well, I thought it would be a good idea to become a member here. Just bought a GPX unit,,seems the host here along with other folks have great in depth knowledge on them. I'm not a nugget hunter,, rather a relic and coin hunter... Every time it seems I was googling about GPX units,, it took me here.
  19. HI just wondering if anyone as ever attempted to take a minelab GPX Series metal detector OFF of the shaft and mount it to a backpack frame? i havnt been able to find any images of a modified gpx......Does anybody know if minelab makes extension cables for the ground balance button? or who might be able to make one? Also does Nugget finder have extension cables available for their coils to make it longer? Thanks ahead of time...... just wondering if its doable....appreciate any input or recommendations! Cheers IG
  20. Wire Free At Last

    Xp deus shaft docs gold screamer and a few different wireless options! Finally got all the peices. Of course I got a bum connector peices for the aptx blue tooth so that will have to wait. I did test it but I had to keep my fingers on the connection while I used it. I must say sounded perfect, there was no lag as far as I could tell. Ready to stuff it in the pack and go find some gold!
  21. Been reading a lot about the new Coiltek, Nugget Finder & now Detech coils of late. I haven't had much to do with any of these but have detected a small area immediately after 2 x GPX4500 with the Coiltek Elite 14" mono attached. Although not an exhaustive or scientific test the end result was I got 8 x subgram nuggets from the area with the SDC & the 4500's nothing. 2 of the subgrammers came from adjacent to their scrapings so they knew something was there but was still iffy enough to walk away from. I keep hearing or reading how these coils are transforming GPX's into SDC's or even GPZ's but this short "test", for want of a better word, put some doubts in my mind. I've got no doubt that there is improvement in the new coils in how they enhance the target information or audio response of the detector through better windings etc. but I'm not entirely convinced it's as substantial as some make out. My thoughts are it may be about 10% performance improvement (every bit does help regardless) & 90% of a placebo effect i.e. you buy a new coil excited by the possibilities of it's performance, you regain some enthusiasm & become more positive in approach even detecting more carefully + with more purpose - then when you find gold of course it's the new coil that done it right? Another thing that has me scratching my head is how excited people are about them finding very small gold. My smallest bit with a GPX5000, fine gold & standard 11" Minelab Commander mono coil was 0.03 of gram (I think about 0.46 of a grain) so they have always been capable of doing it even with an unfashionable coil (but still a good one). Like I said I'm not doubting that there are definite performance improvements, much like the introduction of litz wire, but I do believe a lot can also be attributed to a refreshed or reinvigorated enthusiasm too. New detectors could also have a very similar affect on us. What do the experts reckon?
  22. Just thought I would share my wireless setup for anyone thinking of trying this. I have used Avantree Saturn Pro (Low Latency) bluetooth Transmitter/receiver and some Camcorder batteries. I have also got a couple of Lipo batteries from my RC which run the 5000 really well as they keep their voltage for longer. The leads I made myself with genuine power plugs and a deans RC battery plug and a 1/8 audio jack so as to go straight into bluetooth wireless module. These little module are very good and are lasting well over the 8 hour mark on a charge, and their size and weight make them very versatile. The 7200mah pack and wireless module come in at 325 grams with leads included this lasts about 5-6hours I have made up a couple of 3400mah packs with 18650 cells and these weight 180 grams with module and leads and lasts about 3 hours. I have a 5000mah Lipo hardcase which weight 200 grams with both wires and module, this goes for 7 hours before the low voltage alarm comes. Lipo batteries aren't for everyone as they can be a little volatile, but I am yet to have one explode and treat them with care when charging with a good lipo charger.
  23. My first nugget! Near Scot river. Now I am sure, this quite good beginning, for GPX 5000 and new coil Evolution 17 X 13". Alex.
  24. I have a claim that has lots of very tall thick brush. Tired of getting caught on all the branches. So I ordered a Gold Screamer battery kit for my 4800. Since I am very protective of my GPX I thought I would ask for reviews from others before I used the Gold Screamer. Anyone have any problems using it with there GPX? Thanks in advance. Steve
  25. There appears to be a new genuine by Minelab smaller battery option available for the GPX series. Oddly enough it is not on the Minelab site and no reference to it anywhere except one Australian dealer http://www.minersden.com.au/minelab-gpx-small-lightweight-battery/ Part number 3011-0332 and less than half the weight, 18.6 wH good for around three hours.
