I can't offer any advice unfortunately, but I have to ask whether you've used the 40 x 20 coil yet?

I saw one in use on Youtube and he looked like he was swinging a dining table! :-O

Well you have the largest coil available from Coiltek, the drag coil 40x20", its probably Anti Interference as well. This coil is too large and heavy to put on the end of your stem and was made to be mounted on a home made rig. It would be dragged along by a quad bike.

A more practicable solution would be a 22" Goldstalker by Coiltek or their Elite 18". These are both mono coils so discrimination is not possible. Nexus have recently introduced a 30" Concentric carbon fiber coil which does discriminate and is remarkably light at only 1095 grams.

I would imagine the Nexuse 30" concentric coil would be your best bet. Why dont you contact them at for more information.

I would make sure there was a hoard there first! :))
I had my GPX5000 purely for those situations.
Both were scattered hoards in arable land that had been well detected with pretty much everything else but the GPX still recovered more coins with the 18in DD.
As both sites get deep ploughed every 4/5 years due to the nature of the soil there are still odd ones appearing and there is no pot/purse remaining.
If (big if!) any turn up later this year then the CTX3030 with the 17in coil will "take the lead" on numbers. ::g

I’m not a coiltek fan I use a 12inch nugget finder never comes off my 5000 in Aussie , but in the open field s your commander 18dd coil would be great , quiet and good ground coverage. The Commander coil is underrated , if I’m in a noisy area with emi or heavy mineralisation is a problem I all ways go back to a commander coil. The gpx would be used for finding deep targets in the uk, which is a good idea picking up what is left behind. I have done a lot of testing with coils and 11,12 14, inch coils goes deep and are comfortable to swing all day. In a open field 18 or 19 max for me , and keep your coil on the ground. And yes I’ve tested bigger coils. Pommie Chris.😎
