Detecting with CM Posted January 15 Share Posted January 15 The two coils that I've used for the most part on my machine(s) are the Coiltek 9'' and Coiltek 10'' by 5'' Goldhawks. I haven't used either stock coil in the goldfields yet. Link to comment Share on other sites More sharing options...
Desert Dawg Posted January 15 Share Posted January 15 I have only used the 12x7 exceed Nugget Finder coil on my gpx6000, it seems to run smooth and quiet for me. Yet very sensitive. Link to comment Share on other sites More sharing options...
phrunt Posted January 15 Share Posted January 15 I have the Coiltek 10x5" and the Coiltek 14x9", and I also have the NF Xceed 12x7", without hesitation the 10x5" is my favourite, followed by the stock 11" Minelab coil. I wish I found big enough gold around here for the 14x9", great stable coil but the 10x5" just suits the areas gold better. Link to comment Share on other sites More sharing options...
Bishop Posted January 15 Share Posted January 15 today was my first trip for the new year. also first time out with the new coiltec 5x10. a new wash i was hunting is/was someones honey hole as evidenced by the massive amount of placering and fresh dig holes around. the first target didn't show up for a few minutes and when it did show up in the scoop i was having a hard time believing that the bird-shot pellet was reason for such a loud signal. after lots more lead i did end up getting a little .33 gram bit. also my new coil top scuff guard my mining partner got me. i like the new coil and will go back to the 11 inch only for better coverage when needed.

Gold Catcher Posted January 15 Share Posted January 15 Coiltek 9, ML17x13 and NF12x7. NF never comes off! ML17 I rarely use. Kind of a funny coil. Supposed to go for depth as being a big mono, but appears to just provide more ground coverage with similar performance to ML11. The 6k is generally not a depth detector IMO. I wonder if the GPZ with the NF12 would beat the 6k with the big 17 mono on depth ( I bet it easily does, probably not even need to run hot!). But that's a topic for another thread. 😁 GC Link to comment Share on other sites More sharing options...

RONS DETECTORS MINELAB Posted January 16 Share Posted January 16 Having all 7 available coils at different times, I will say the Coiltek 10 x 5" is a favorite coil for its sensitivity. The 17 x 13 is no slouch even though its not far behind the 11" on multi-gram bits, just have to lower sensitivity to manual 2 or 3 to handle the ground and EMI chatter and get that smooth threshold.

Detecting with CM Posted January 16 Author Share Posted January 16 The NF 12'' by 7'' might be a more desirable coil if it was more sensitive along with being quiet. Link to comment Share on other sites More sharing options...
Gold Catcher Posted January 16 Share Posted January 16 I have not used the 10x5, but compared to the 9 round the NF 12x7 is more stable in my hands. And without significant sensitivity loss compared to the stock 11. But those are just my observations. Btw, I have no problem with edge void of the 12x7 and find this a terrific coil.

Thanks. I think the difference might be more significant with gold at depth in hot soil. The ground processing of the Z is unmatched IMO, and even smaller super D coils can hear targets rather deep.
