A New Concentric Coil Coming For The Earlier GPX 4500/5000 Series From X-coils

That's what I'm interested in most too, the earlier GPX can make an excellent beach detector, and with the Concentric depth, being in DD mode as a Concentric cutting out a lot of EMI.    Just need to screw these little things onto the switches to prolong their life when exposed to sand.  

If it cuts out EMI as well as a DD yet provides Concentric depth, I'll be super happy, top that off with good ground handling for the black sand and it will be ideal for me.  Having the discrimination is another bonus I guess, I'd need to play with that a bit to see how I like it.

I've had to use electronic contact cleaner on my potentiometers and switches. I never seen those little switch covers. Talk about durable, at one time I could hardly turn the potentiometer to change timings ? Sprayed it well and it works fine now. I think I'm going on about  at least 4 or 5 years of hunting beaches with the 5000 and it's like a tank. I would buy one of the X coils if it gets me more depth than the DD coils do. Cautiously optimistic to see what happens.

They should be at your local electronics shops, often called Toggle switch rubber boots.  Here is amazon linking to a heap of them, just need the right screw thread size and a rubber boot long enough for the switch, pretty easy to find if you go into a shop with them and check them out.

The early GPX models are built like tanks, the contrast to the 6000 is vast.

I'm really looking forward to trying out this Concentric coil and looking forward to using the early GPX again as it's been sidelined since the 7000, and I've done a fair bit of work to mine since getting the 7000 with the carbon shaft, external speaker and lithium battery, none of this I had when I actively used it often.

Me too.....but I'm confident the price will stop me in my tracks.

The 6000 for me is uninteresting, no matter who makes a new coil for it ?. I now use it to prop up all my other detectors. Makes a great book end?

That makes for an expensive book end. What is at the other end, A GPZ 7000? That's an even more expensive book end.

As much as you poke fun at the 6000 & its short falls. It does well at finding gold.

No GPZ for me, unless I want to be single again ? I do poke at the 6000 and I'm not knocking it's ability to find small gold (and more). For finding small targets (like the tiny brass beads I was looking for) it smoked my 5000.  For me the problem always has been the labeling of the machine as a GPX in the first place. I would imagine that boosted sales a bit, but in reality in isn't anything like my 5000. I bought it thinking it was the next in line and would be better than the previous version, but for what I usually use the GPX for (beach and relic hunting), it is not better. So it sits on one end until someone else is unhappy with their 7000 and mails it to me. ? Bookends are better in pairs.

I agree. The GPX 6000 should never have been called a GPX. No similarities at all to the earlier run of GPX's. Minelab certainly have their weird moments.

You really need to try an older GPX on this ground, especially with a DD coil, I think you would be pleasantly surprised.  Borrow or hire one or something, there has to be a way to try before you buy.  Someone may meet up with you with one.  If the concentric deals with it in DD mode while also controlling EMI and having some decent sensitivity I will be a very happy person.

These rock formations are quite weird, I don't know if lava caused them, but they're nasty to detect and smash up to try get targets out of them.  There is no soil there, it's all rock.

That rock is called polymictic conglomerate. Common in some places here to mate.

The stuff here dose not carry gold like normal sandstone type conglomerate but it can be intruded by gold bearing veins.

Not sure about your NZ stuff though if the water course that made the clasts was auriferous it will be.

Ours pre-dates the gold mineralisation events so keep these options open when prospecting the area.

That type of conglomerate is prone to brittle fracture which is highly favourable for gold vein intrusion. Also some types have clasts that are chemically favourable for gold precipitation. Good rock most of the time.

Thanks Goldhound, good to hear from you, I hope all is going very well and I appreciate the information.  Sounds like I need to put a bit more effort into these areas.

It's looking like the 15" GPX Concentric will be $490 USD delivered express.

I'd say that is reasonable if the performance is there.

I can't use my 15" on my 7000 at the same time as the 5000 but there may be some performance differences worth the effort and expense.
