A few months ago when talking to the guys at nugget finder about coil options they hinted at a new small coil coming out soon, here is the news i was waiting for.
Some exiting news for GPX users, a super sensitive coil with good ground coverage in the evolution windings, will be interesting to see its performance especially compare to the new coiltek 9" and also the SDC.
From the nugget finder website https://www.nuggetfinder.com.au/products
A NEW EVOLUTION IS COMING
The 12"x8" Evolution will be released in August 2018
AMAZING SENSITIVITY COMBINED WITH GOOD GROUND COVERAGE
LIGHTWEIGHT - ONLY 740 Grams
More Details and Pictures soon to be released!
I will be talking about as I use and test.
I will be comparing to Etrac wearing 6”coil, Deus wearing elliptical Hf coil and Nokta Impact wearing 4x7” elliptical coil.
Will compare to stock Equinox 11” coil too.
Lately, I've been experiencing the coil overload problem. Its hard to say whats causing it but it happens often. Probably not the best thing to do but I tend to slightly lean on the detector as I'm digging a target with the coil firmly against the ground. I've done this for a while with no problems before. It only shows the overload signal or shuts down when the coil is pressed against the ground. I've noticed it happens when using different coils as well. The only thing that has changed recently is the settings I use. I often have the rx gain flat out at 15 (gpx 4500) and other setting quite high also. Is it possible that the more extreme settings (when the coil is in contact with the ground) are the cause or is likely a problem with the machine?

I have a Garrett ATX and have done some nugget detecting with it. See Gold Nugget Detecting with the Garrett ATX. However, the weight and the stock coil had me wishing for options. I wanted a smaller coil with no openings to hang up that could get into tighter locations. As a past Infinium owner the 10" x 5" DD coil immediately came to mind. See Detecting with the Garrett Infinium in Hawaii and the first picture will tell you what was going through my mind as I hunted gold nuggets.
So I have some Garrett Infinium coils I am trying on the ATX. The full story and photos are at my new Garrett ATX Accessory page. I will be updating it as I experiment more with the concept. An obvious alternative would be to make an adapter to mate a standard lower rod assembly to the ATX (it has already been done for the Recon) but I wanted to go hip mount for the least weight on my arm possible.
I want to note here I am advocating nothing and recommending nothing. This is just something I am doing that may answer some questions for some people. If nothing else it will save somebody else making a duplicate effort or wasting the time and money on something that may or may not work out. Bottom line is I just have to know for myself so I will find out and report back as I go along. This thread will be the official question and answer thread for the experiment.
