mn90403 Posted June 27, 2017 Share Posted June 27, 2017 It seems that you are given enough sensitivity that it can be overloaded. Probably better than underloaded. How is the discrimination? We have an area where the ironstones sound just like gold to the 7000 and we have to dig everything. Would the monster tell me the difference between an ironstone (grabbed by a magnet just like steel) and gold? What if that ironstone had trace amounts of gold in it?

Randy Lunn Posted June 27, 2017 Share Posted June 27, 2017 A nice collection of nuggets Lunk. Well done. In prior posts you and others have observed that even the little guys hit pretty hard. Did these nuggets respond crisply or subtlely? Any additional comments on the GM's nugget response profile? 1 Link to comment Share on other sites More sharing options...

Mitchel Mitchel, when the Monster is swamped it gives a distinct overload alarm so that you know to back off. And the iron discrim is excellent. As far as how the Monster copes with hot rocks and ironstones in particular, see my previous post on the subject here: 1 Link to comment Share on other sites More sharing options...

Thanks Randy, Even the tiniest pieces give a crisp response close to the coil, however at the edge of detection depth targets give a weaker response and many times only in one direction of the coil swing. These kinds of targets won't activate the gold chance indicator until the coil gets closer to the target. 3 Link to comment Share on other sites More sharing options...
mn90403 Posted June 27, 2017 Share Posted June 27, 2017 Lunk, Thanks. When you published that report I didn't really 'understand' the Monster language. Now I do even if I don't own one. If you can track out an ironstone and by some chance get an indication of a little gold in that rock ... Hopefully more people will reread your report you linked to me. Thanks again.

Lunk Posted June 27, 2017 Author Share Posted June 27, 2017 I should add here that the hot rock elimination seems to work best at the auto sensitivity setting of 11. 1 Link to comment Share on other sites More sharing options...
Norvic Posted June 27, 2017 Share Posted June 27, 2017 Gotta agree the hot rock elimination of the auto sensitivity 11 is pretty good. With its sensitivity setting range in both auto & manual and auto HF GB the Monster, as is, while not a competitor to the Z or PIs (except on shallow scraps) jcomplements them, suspect it may be the start of a new era for the VLFs. Certainly has brought back the VLF fun to my prospecting although certainly not a weight producer. A challenge to the other manufacturers for sure. 5 Link to comment Share on other sites More sharing options...
Sourdough Scott Posted June 28, 2017 Share Posted June 28, 2017 It seems like the hot coil is the 5 inch round. Anyone been using the other 6 x 9 elliptical coil with any success or issues? BTW, my Gold Monster arrives July 3rd. Yippee. Klunker says we are taking the whole week off to go test it and report back to HQ. 1 Link to comment Share on other sites More sharing options...
Steve Herschbach Posted June 28, 2017 Share Posted June 28, 2017 I am using the GM1000 pretty much exclusively with the large coil. I have no issues with coil knocking but I am usually running exclusively in deep seeking all metal mode with Auto+1 or manual sensitivity between 6 and 8. 3 Link to comment Share on other sites More sharing options...
