Big Coils -- Do You Still Use Them?

Recommended Posts

Largest coil I have swung is the same 25" Nugget Finder as Reg mentioned, but on the GPX 5000

Notice the swing arm fashioned out of a broken fiberglass shovel handle.

For where I hunt and the gold I get over, large coils have been something that never work out to be as magical as I hope. 14" to 18" coils are a much better fit for me in general.

It's amazing how much expense anyone with a bit of imagination can save by making or modifying/repairing their own prospecting gear. In this day and age of diminishing gold returns every penny saved is important.

It seems to me that the market for prospecting and after market gear is heavily loaded towards the affluent weekender.

Sorry Mitchel! Off topic, rant over!  :angry: :wink:

Good rant JR, but I think we are left behind the times a wee bit, our soldering irons, silastic solutions, etc  and don`t forget the duct tape fixes everything solution. But it is bloody good fun, me I just feel so privileged to have lived in the electronic gold rush age, may we all score a hundred and still be swinging big coils, little coils or whatever to get some weight.

I broke the swing arm on my  7000 so this was my fix. It has been through the fight and prevailed.

My everyday Coil is a 14x10 DD, It weighs a few grams less than the factory 10"DD but it adds a few inches more depth and is very sensitive, The 14x10 DD is a better option to the 12" Concentric because if the ground hots up it does not loose depth and it is way lighter @674 grams, I also have the 15" MXT Max Concentric Coil but it is a bit unbalanced weighing in at 1047 grams,

what would the best big coil be? sounds like the nf25 is popular. I have 14"elite and love it, I want something big to check all my spots. I know I'd love the 18 elite but I figured if I'm gonna get a big coil and deal with it just to check spots, well why not get the biggest

The three spoke 25" Nuggetfinder is very light, and very stable.

There's  a place for large coils, for me a 18" Elite is max size for the areas I hunt....I've found some deeper gold in place I have cleaned up, and just yesterday a small tid bit of 4 grains at 3" ....

      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?

      Hi,
       
      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.

      Any one know if the ctx coils interchange with the equinox beside the mounting on the shaft?

      Does anyone here know what the weight is for the new slimmed down D2 coil.  I know the old one was really heavy.  Is the new one much lighter?

      I own both a Garrett Recon and an ATX, can someone remind me what was found to be best 10 x14 Infinium coil to be used on each? 
      I was thinking someone found the Infinium 10 x 14 mono coil was best for Recon
      and Infinium 10 x 14 DD coil best for use on the ATX
      Is this correct or are all interchangable?
