oldmancoyote1 Posted July 21 Share Posted July 21 As I understand it the 11 inch DD Minelab coil is the recommended coil for initial use in a new area. Mine is dead. Should I buy an identical coil as a replacement or does current technology offer a better option? Also any comment on the Chinese $60 clone? 1 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/ Share on other sites More sharing options...
Gerry in Idaho Posted July 21 Share Posted July 21 You probably have near 50 different coil options for the GPX-4500. Heck, maybe even closer to 100? Don't read into the manual to much as most of us here in the US prefer the MONO over the DD because of greater depth and also increased sensitivity. I don't think you need to purchase a new one but having a DD in your arsenal is a wise decision. As for the Chinese knock off. I don't care if it's free, I wouldn't even hook one up to my detector. In harshest soil conditions a DD runs smoother. Realize many areas in OR, ID, NV, AZ, the average nugget locations are not that bad of soils and MONO is preferred. DD coil is great for the few folks who like using the IRON ID feature of the 4500. It does take a little practice but worth it. If you are on a budget, I have a used Factory Shipped 11" round DD with col cover for the older version SD series and would let it go for $60 shipped. My personal favorite was the 10" ELLIP DD as it was great for getting into tight hard to reach areas. 8 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-277619 Share on other sites More sharing options...
PhaseTech Posted July 22 Share Posted July 22 11" GP series coil is a very good coil and very underrated. 4 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-277679 Share on other sites More sharing options...

Gerry of Gerry’s Detecting offer for that 11” GP DD coil is a great deal. That coil will work well on your 4500. 1 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-277694 Share on other sites More sharing options...

But mine became very touch sensitive over time.

RickUK Posted July 22 Share Posted July 22 I personally use the Detech 11'' DD AI coil on my 4500 because of the Iron Rejection on my Saxon/Roman sites,we dont tend to nugget hunt here in the UK......but my favourite coil when i can locate on is the 10'' DD elliptical but i think i have located a new one and will have it by the end of the month. The reason i went for the Detech DD AI coil was the fact that the only site that really requires the AI is a roman trading villa sites which is about 40 acres and right next door to the site is massive pumping station which emits no end of EMI and also the ground is almost black due to high mineral content,so the weapon of choice for this site is a GPX and also the DD AI coil and it does work exceptionally well. 1 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-277705 Share on other sites More sharing options...
dirtman Posted July 25 Share Posted July 25 Forget Chinese anything when it comes to hooking up to a Minelab. As for your dilemma with the 11" DD. An 11" Minelab Mono will "serve" you much better. It made the difference between Quitting Detecting for nuggets or finding a 1st nugget for a few people I've detected with over the years. No baloney 👍🤠 Happy Huntn 3 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-277871 Share on other sites More sharing options...

Thanks for the offer Gerry. After reading your advise and others, I have decided instead to develop skills with my 11" Minelab mono coil and my 14x7 and Sadie Nugget Hunter mono coils. I work exclusively in the Klamath Mountains of Oregon and California. Do you think that could work well? 2 Link to comment https://www.detectorprospector.com/topic/26262-replacement-for-my-gpx-4500-11-inch-dd-coil/#findComment-278518 Share on other sites More sharing options...
