Steve Herschbach Posted March 29, 2021 Share Posted March 29, 2021 Welcome to the forum - nice little nugget If I was going to Southeast Alaska, I would take the Gold Monster before the GPX 5000. The gold in the region is generally very small, and in general it’s hard rock country, not placer. Glacial terrain, high mineral coastal belt. The mineralization calls for a PI, but a GPX 5000, no matter what coil, will never match a good VLF on small gold. A GPX 5000, I would get either an 8” Commander Mono, or Nugget Finder 6x8 Sadie Coil, and try to run Sensitive Extra The problem with small gold is you need a hot detector. But a hot detector struggles with bad ground and hot rocks. It’s a balancing act. Sensitive Extra may be too hot for your area, so use Fine Gold instead. It can handle the hottest ground, but it misses more gold than Sensitive Extra. And the fact is neither setting on a GPX 5000 will be good on the smallest gold, that a Gold Monster can easily hit. Frankly, I’d go SDC 2300 before GPX 5000 for your region. With an eye on the new GPX 6000. But for working with what you have, I’d grab Gold Monster first. If the ground defeats it, then GPX 5000 with Sadie coil. Glacial terrain offers complex challenges for metal detecting, with gold almost anywhere or nowhere. Glaciers are like bulldozers, mixing and making a mess of everything. Placers are very new, generally lean. Learn about things like moraines and eskers, and study where water flows around existing glaciers for clues. Gold placers can exist in lateral moraines halfway up valley walls. Like I say, use your imagination, and put the coil over everything. Good luck! Glaciers and Gold Link to comment Share on other sites More sharing options...

I don't think he (yet) has a GM 1000 but rather a Minelab X-Terra 705 with 6" 18.75 kHz coil.... Link to comment Share on other sites More sharing options...
Steve Herschbach Posted March 29, 2021 Share Posted March 29, 2021 Then I’d grab the X-Terra first, same story, different VLF, though the Monster is a little hotter. Link to comment Share on other sites More sharing options...
