Hi guys,
Got hold of a 4000 for a while.
Heading out Sth of Castlemaine for a bit.
Can anyone please suggest the best coil for me to use.
Cheers,
Rhodes.

I am also rather new to detecting only been out twice before , thanks.

Ok so what coils do you have to choose from?

I would suggest a mono coil running with 'sensitive' timings and run factory presets as you learn the machine. Perhaps even pick up a small nugget to use as a test target to help you learn. It only needs to be about 1/2 gram.

The other thing would be to read the instruction booklet and watch youtube videos to help familiarize yourself with the machine.

If you want to understand more about the detector in general and how the settings work, here's a video I did a little while ago for our local PMAV branch.

Hi Rhodes, what coils have you now?
Frequently people have the standard Minelab mono coils which are fine. Starting with the minelab you will find gold if you have your detector setup correctly and happen to walk over some gold. Dont buy anything until you have practice.

Cheers

Great advice Pat & Harry thanks.
I am getting the machine this weekend , will let let you know what coils it has soon.
Thanks for the vid link as well Pat!
Kind Regards,
Rhodes.

 

[Rhodes]

So I found out it is a mono coil , not exactly sure what size thought yet.
I also watched your vid Pat will watch again and take some notes, followed a lot of it though. Very informative.
Pretty sure time out on the ground will be a big factor as well.
Cheers Rhodes.

Around Castlemaine a minelab 8 mono will do well but if the detector has a 11 mono only just use it until you get formilular with the detector . if its got a 11 DD then switch it into mono mode regards john :Y:

 

[ctxkid]

what's the best thing to put on my new detector ??.........

coil time

 

[PhaseTech]

Yep, I'm with John, 11" Commander mono in Sens Smooth is going to run super stable. Will speed up your learning process.

 

[Rhodes]

Okay thanks phase and hand thanks for that, will keep you posted.
Rhodes.

 

[Rhodes]

Why is the 8 good but the 11 not so good Oldhand?

 

[old hand]

The 8 inch is more sensitive on small gold around Castlemaine on the red clay and the heaps its quite good :Y:

 

[Rhodes]

Okay copy that?

depending on condition any photos mate

I always check Coiltek Gold Centre prices on their used detectors as a guide:
https://www.marybroughgoldcentre.com.au/pages/second-hand-detectors
They sell their detectors as a stock or close to stock package with some warranty (3 months I believe).
With that in mind a good condition stock package should get close to their price - GPX4000 $2000 - $2200.
If conditions a bit rough but the detector works fine then it will be less & if you have a lot of extras it will possibly be a bit more. Sometimes it's better to offer a stock package with a few extras as sweeteners & sell any higher priced extras off separately. You can get a few extra dollars for your gear that way IMO. Some people want the extras for nothing.

 

[PhaseTech]

Yep, the Coiltek prices are a good indicator at the moment for standard packages, 1 or 2 standard coils:

Obviously condition and included extras, and whether the unit comes from a dealer with any warranty all play a part in final price.
But as with anything used, it is only worth what someone is willing to pay.
