Need Information About A Pulse Induction Purchase Decision!

     I don't think anyone's "swinging" that coil, unless they are built like Hercules!!💪👍👍

Don't think the coil leaves the ground, the shaft probably flexes like a car antenae hehe. That is cool the large coil can hit small silver though.

   It creates such a strong magnetic field, you can ride it like a magic carpet!🧞‍♂️  👍👍

For JohnnyRox and Chase Goldman,

15 x 12 coil
Field 2
Sensitivity = 25
Manually crank up the ground balance to 99
All Metal
Recovery delay = 1
Iron Bias = 0
Multi Frequency Seems just as deep and is probably superior to 4khz

Anyways, WHen you get the quarter all the way back to the 22 inch mark Start out passing it extremely slow. If it wont double beep, Slowly increase the speed you are passing your target until it does double beep. Ive noticed that even with Recovery Delay set at 1, Sometimes a FASTER sweep speed is required to make the target double beep. Thats just the way it is. THink about that when you pass a target up because you cant get a double beep. 


Thank you for the reply Larry.

Hey Chase where'd you go pal, thought you were interested in how Larry got the depth he claimed?

 Actually, I did thank him, over a week ago, so I am missing your point.

My understanding from speaking to the guy and hearing about it quite a number of people in Europe especially Russia use a GPX for finding coins, all sorts of coins and artifacts.  The reason is for the depth they can get, with many finds being not just hundreds but thousands of years old they can be very deep.

This is one guy that uses the forum and his finds from around Russia using his GPX 4000 and his F75.

And this is his detector, note the size of the coil he is now using to get the really deep old coins, 26".


I've only just started using my GPX for coins but my initial testing is it has no trouble at all with depth on small silver coins.

The Vallon VMH4 PI has an optional 60cm coil. Haven’t been able to adjust the sensitivity above 70% and it hits pretty small and pretty deep with the 30cm coil.

Not a gold nugget machine, but behaves pretty identical. It just loves to ride on the edge of ground signal.

I've found the Fisher AQ weak on silver so I'm not sure how the Terra version would do on land on silver. I have spots (in the water) there are some old coins...... it seems every time I take the AQ I may get a piece of silver, but does good on the Nickels..Then I go thru with the excalibur and it cleans up on all silver (several pieces) and nickels....same spot. The bad about the AQ not hitting hard on the coins  ..old deep coins are a sure sign there is deeper gold near. So I need to find the correct area first with the excalibur then come back with the "AQ"..

      So I'm still trying to milk the same cow 😄 I figured until it stops spitting silver on me, I will continue to ask for it. Long day at the beach 8:30-5:00, but the weather was decent, as I dress well for the cold. I'm getting to be a delicate flower in my advancing years 🤔 I'm using the GPX all day for this hunt and digging select areas and removing all iron so I can hear the deep targets.I hit a patch that started producing exclusively wheat pennies, so I knew that the chance for silver was very possible.  It did produce some silver but the ratio was mostly pennies. Moving over just a bit, the wheats turned into memorials and the clad followed as well. Not a bad day with 8 silvers, but I worked harder than usual for it.The beach is slowly sanding in and the easy stuff is gone. No gold again, but switching the timings on the GPX did start getting me a lot of nickels, including a handful of Buffalo. Jewelry was missing as usual, but the spoons sure weren't lacking 🙄 So here is everything I dug. Lots of junk too. It was great to get out and enjoy the hobby.

      That  is a lot of money to spend where their are not to many nugget spots .Will it help relic hunters in hot ground over the other PI machines ?

      I opened up my TDIBH the other day for some fiddling around and checking out a few things. I powered up the detector with all of the guts and board opened up and had it hooked up to the 14.8v (4 x 18650 cells) battery pack. I had it going for just a few minutes when I gripped the circuit board as part of my “fiddling” around......well I dropped the board and swore a bit in response the burn I was expecting on my fingers. Well it turns out that on the opposite side of the board behind where the big capacitors sit is some sort of heat sink and I can tell you the heat from this spot was something else. The detector has and runs just perfect but the hotspot really surprised me. 
      I decided to hook up the 12v battery pack and let it run for a decent amount of time and it never got past a mild warm on the back of the board. That extra couple of volts is generating some serious extra heat.....bit like on the heat sink area of the CPU chip in your computer.
      I honestly don’t know if the detector can handle this extra heat long term but I’m not taking any chances. I’ve moved back to the 3 x 18650 battery pack which I knocked up when I first got the detector. There is a slight loss in depth but surprisingly not too much. I feel the performance of the 11.1v Lithium setup is maybe 1 to 2 inches behind the 14.8v “hot pack”.
      You can see in the photos the big caps on the detector and where the heat comes from. The other photo is my 11.1v pack which packs some punch and lasts much longer then the stock NiMH pack.

      Thanks to James Beatty for mentioning this Russian site that shows pictures of the 6000"s internal circuit board.
      I was reading the comments (translated) and noticed that Steve and his comrads are held in high regards in Russia as well.🙂
      Quote: The circuitry of this device and me, too, "amazed to the core"! Made "very good" (really good, no kidding!), BUT why done - absolutely incomprehensible! (SIXTEEN (!) IMPAD / Pirates "In one bottle" !!! IT'S COOL !!!) It will be interesting to know what The "result" of using this technology in real search? I think that Steve Hershbach "and his comrades" will discuss this device and will experience "the full program" - this is their "theme".

      I tripped over this by accident while looking for info. Looks like a simple brochure handout, and what is interesting is the GPX 4500/5000 is missing in action.
      This might be Africa only, as the old GPX models are now so commonly counterfeited there. The best way for Minelab to address counterfeiting is to not let old models exist for too long, and the GPX 5000 is an ancient design at this point in time. I also suspect that there are increasing issues surrounding the shipping of that massive Li-Ion battery. Long story short, I can see why Minelab would want to discontinue the old GPX models
      The U.S. is a bit unique in the number of GPX 5000 used by relic and beach hunters, which might keep it viable here for longer than might be the case elsewhere. The GPX 4500 has long been rumored to be on its last legs, but it continues to be listed for sale. Plus, issues surrounding counterfeit detectors are far less severe here than overseas.
      Still, in the long run it makes sense to discontinue the older GPX models eventually, since the GPX 6000 is a clean break from the earlier designs, with no carryover of coils or other accessory items. This little brochure hints at a probable future without the GPX 4500/5000.

      Yesterday evening I was paging through all the post on the 6000 when out of nowhere here was this ad showing what looked like a Garrett ATX ad . The head looked just like ATX but was on a shaft like all other land detectors . The control box  looked a lot like the MX 7 and it was under the arm .
       I’m not sure what the ad said but it was something like;why wait when it’s here now.
       I’ve went to every post and I’ve can’t find it. I’m hoping someone else seen it to.
       I know I’m a few grapes short of a fruit salad but this was real and I wasn’t dreaming.
