Been using the 18" after market coil on the GPZ7000 now for a few days, mostly going over some areas where the 14"GPZ coil was very successful, nothing big and deep has been found, the biggest was today, a 4.75 gram piece, with some still attached red  matrix, the coil has been running well and can be used all day just like the original 14" coil with out arm fatigue.  The benefit so far has been the extra ground coverage, I can only hope to swing over a big deep one. Smile

4.75 gram piece

Hi Dave,

Beautiful piece of gold, good work! Though it's not a monster lurking down deep it still is a nice find by today's standards. Like you've written in the email, I too noticed the new coil being more sensitive and able to pick up targets further from the edge than the standard coil. I found it helped a lot getting under bushes and patch-hunting. Good luck out there and looking forward to seeing more of your finds.

Thanks Stan, the coil is going good, still nothing big n deep, but I have found 55 nuggets varying in size for 36 grams since I started using this coil, that for a bit over a weeks detecting.

Been out detecting and using the aftermarket coil some more, and alternating between the 14" GPZ, both coils work well and seem to be getting the same gold, the extra coverage of the 18" coil is a benifit and it's way lighter than the GPZ19" coil.

The biggest nugget I found with the 18" aftermarket coil was a 4.14 gram at around the 8" mark, that's not deep you say, but the ground was extremely noisy and had been gone over with the 14"GPZ coil previously and may have just been missed as this can certainly happen.

I never even tried to do comparisons, as it's a lot of bother to carry or go back to camp and change coils etc, all I know is both coils work well and respond very well to targets.

A picture of the 4.14 gram nugget.

Nice going there Dave, well done. I did say in one of my previous posts, the weight advantage factor alone, coupled to ground coverage, make this new 18 inch GPZ coil, well worth investing in.

Some pictures of what's coming, Stan asked me to post these coil pictures of these aftermarket coils for the 7000 that will arrive soon for testing in Australia.  Even the 18" coil that we have both been testing has been revamped.

Interesting to say the least Dave. Now if the other 3 newly made coils, prove to be as good/stable over mineralized ground, as that of the already proven/tested 18 inch round, for their lightweight design & manoeuvrability alone, will be worth their weight in gold.  Definitely something to look forward to. Thanks Stan/Dave for their introduction.

That 10 x 9 coil will throw the cat amongst the pigeons if it behaves and does what its told to do on the small gold....... very interesting.
If it works I'll have to sell the SDC (surplus to requirements) hey Dave?
By the way, that looks like a great pick you've got there, where did you get it?

Yep that's for sure, I am keen to test that one as well.

The pick, well it's one of my "Gold Digger Picks" that I make and sell and supply some of the detector shops Very Happy check in the commercial section of this forum. Very Happy Very Happy Very Happy

2 new aftermarket coils (10" x 9" and the 18") for the 7000 have arrived in Australia, Stan will giving them a good test over the next month or so. Will be very keen to see the results.

Two sizes that many of us 7000 users would like to have as part of their arsenal Dave. Being solid filled & much lighter in weight coils, would also make them Ideal for Victorian ground condition use. I take it they do come with skid plates attached?
Now fingers crossed, they operate/function well over mineralized soils Stan.

Yep your right there Kon, looking forward to getting to use one of these, I know the previous 18" proto worked very well, and yes it came with a skid plate attached, and I'm reckoning that these will also. Very Happy

The versatility & lighter weight of that 10x9, working in amongst thick scrub or rocky terrain, is something that many of us have been waiting for.
Large open spoke coils, get caught up in/over protruding ground objects with just about every swing & are a struggle to use here in Vic. Having a solid filled, large 18 inch round coil, with similar or close to weight of that of the 14x13 inch GPZ coil, but offering to some extent better depth, over larger bits of gold, sitting buried deeper in the ground, would be more than advantageous/welcome.

Dave are these coils plug in and go or does one need to change the plug from a , say 19" ML coil that has the chip for these coils to work?

Unfortunately not plug and play, you need to make a patch lead from an existing GPZ coil, I made mine from the GPZ19" and all worked well, and then also put the 5pin mic plug on the cable for the GPZ19" coil so it can aslo be used again.

This is the patch lead I made.

You can use the GPZ14" coil it makes no difference which coil, Stan made his patch lead from the GPZ14" coil and re wired a 5pin mic plug back onto it and then either the new aftermarket coil or the original GPZ14" coil can be used.

Whichever one is used is the one the 7000 still recognizes and is happy to run like that.

Dave , when you compared the 19"GPZ and this 18" coil what depth differences have you found between that 2 coils?
Also the 14" v 18" has the 18" coil gone any deeper ?

And when are these coils be for sale in OZ ?

I never done any swapping of coils on targets for comparisons etc, as you know whenever anyone has done this in the past all you get is complaints about how it should have been done differently. All I was interested in was that it worked and worked well on the 7000 (18" prototype coil) and the next model batch of updated coils that were tested were not satisfactory, they were way over sensitive and noisy on the WA ground where they were used.

They will be for sale in OZ when the testing has been completed which means testing more of the original prototype configurations.

Hi Dave
I would have thought now that you know that the coil works that there would have been some comparison between the GPZ 14 & 19" v the 18" AM coil
If the 18"AM coil only goes as deep as the 14" ML coil, other than coverage there would be a limited market for the coil
Should the 18"AM coil go deeper, then that's a different story
Just thought someone would have done the comparison by now on a undough target with the same settings
That was all
