Been reading a lot about the new Coiltek, Nugget Finder & now Detech coils of late. I haven't had much to do with any of these but have detected a small area immediately after 2 x GPX4500 with the Coiltek Elite 14" mono attached. Although not an exhaustive or scientific test the end result was I got 8 x subgram nuggets from the area with the SDC & the 4500's nothing. 2 of the subgrammers came from adjacent to their scrapings so they knew something was there but was still iffy enough to walk away from. I keep hearing or reading how these coils are transforming GPX's into SDC's or even GPZ's but this short "test", for want of a better word, put some doubts in my mind.
I've got no doubt that there is improvement in the new coils in how they enhance the target information or audio response of the detector through better windings etc. but I'm not entirely convinced it's as substantial as some make out. My thoughts are it may be about 10% performance improvement (every bit does help regardless) & 90% of a placebo effect i.e. you buy a new coil excited by the possibilities of it's performance, you regain some enthusiasm & become more positive in approach even detecting more carefully + with more purpose - then when you find gold of course it's the new coil that done it right?
Another thing that has me scratching my head is how excited people are about them finding very small gold. My smallest bit with a GPX5000, fine gold & standard 11" Minelab Commander mono coil was 0.03 of gram (I think about 0.46 of a grain) so they have always been capable of doing it even with an unfashionable coil (but still a good one).
Like I said I'm not doubting that there are definite performance improvements, much like the introduction of litz wire, but I do believe a lot can also be attributed to a refreshed or reinvigorated enthusiasm too.
New detectors could also have a very similar affect on us. What do the experts reckon?
Just curious how it does on depth and sensitivity. Has anyone tested the Elite with some specimen type gold that the GPX misses but the 7000 screams on? Is anyone even running one over here? Most of the comments I see are in Australia. NF looks to also be coming out with a similar coil. I'm just curious how much and what sorts of improvements they give.
There have been a fair few people asking about X-Coils for the older detectors, GPX4500/5000 etc
Now we have X-Coils for the GPX 4500/5000 a 12" spiral round, and a 15" spiral round, and then a 15x10 spiral, and also a 17x12 spiral, and a few of the 12x6 size coils are out in the field being tried already.
So I'll be heading out to give these a run over the weekend and guess what, No patch lead needed.

17x12 spiral for the GPX
12" spiral round for the GPX
15" spiral round for the GPX
I often wondered why X-coils came out of Russia, I know Russia has a big interest in metal detectors and has a large user base of metal detectors but I always assumed it was relics and coins that were big there like in a lot of Europe. I never knew Russia was a country with a lot of gold. Then I looked it up and to my surprise Russia is the 3rd largest gold producer in the world.
A caption from a website about Russian Gold.
Russia recently established itself as the 3th largest gold producing nation in the world, behind China and Australia. With over 11% of the earth’s total land mass, Russia is also estimated to have the 3rd largest gold reserves in the world, with much of that gold yet to be recovered. An archaic regulatory process has limited development of many lode resources throughout the country by various mining companies. Despite these setbacks, Russia is considered to have some of the best potential for future development for gold mining in the coming decades.
You'll see in 2018 Russia was only just behind Australia in gold production with China in first place. Sadly New Zealand doesn't even make the list 😞
Russia is also known for very large nuggets, some of the known big nuggets are:
A 14-pound gold nugget called the “Devil’s Ear Nugget” was discovered in 2014.
A 22-pound gold nugget was found as recently as 2017.
Russia’s largest gold nugget – a 79-pounder was found in the southern Ural Mountains.
You can read about it on this website
Now that I know these facts it's no surprise at all X-coils came from Russia, It's also no surprise that the manufacturer of the X-coils is himself a prospector, and a very successful one too.
Here is a couple of videos of him finding some large nuggets using the 12" Spiral wound X-coil on his GPZ.
And some of the Gold he found recently.
Now it all makes sense why the X-coils came from Russia. It makes my little sub gram nugget finds look very tiny 🙂
