Coiltek Elite Mono Coils

Recommended Posts

I’m in the market for a new coil for my GPX 5k since the others have seen better days etc. 

I’ve seen some good reviews regarding the coiltek elite series and had a couple of questions regarding them. 

I detect in the sierras with pretty mild ground for the most part. The gold ranges in size but, generally under 5 grams and pretty rough/prickly. I know the 5k doesn’t handle that kind of gold as well as say the Zed, but my buddy has one of those. 

My big question is whether to go with the 14” mono or the 17-11” elliptical. Any advice here would be appreciated as I hope to make this the go to main coil. 

And if there is another coil I should be considering as well please share your opinion. 

Thanks!

I`ve not used any of the flat wound coils because they came out after I bought the 7000, but generally the round coils go a bit deeper than the ellipticals so unless you are going for ground coverage I reckon the 14 round would be the go.
Again I`ve not used any of them, but I have heard some very good things from a few people about the NF 12" round Evolution. Dave

As Phonix pointed out you will get better depth with the 14" round. Having said that I know the the 17" x 11" will punch down deep as well having helped dig out a 5oz piece from cap rock at a measured 25 inches.

For its size the 14" is very sensitive on small sub gram bits having seen the results of someone using one. I've used the NF 12" Evo and can attest to its ability to pick up small bits and have dug a 2g specimen from about a foot here in Western Australia.

Mark ?

The new flat wound coils can start to play up on hot days as the ground heats up, I found that out while detecting on days with a temp range in the mid 30's where at times I had revert back to standard coils for the hottest part of the day. The 14 Elite is a great coil just like nugget finder Evo coils but with the advantage of a pressure release valve to help combat hot conditions. If the gold tends to be smaller like you mentioned under 5 grams with shallower ground, the 12" evo would be my pick on the Gpx.

Yep, I agree with Joe, if a lot of the gold is rough and prickly you want a smaller coil for that added sensitivity. But, my preference would be a 14x9" (NF, have not tried the Coiltek version).

I have the 17x11 and it was my go to coil for quite a while. Punches deep, easy to pin point and is sensitive on small bits.

That being said, the 14 will punch a little deeper but isnt as easy to pinpoint and maneuver in between grasses/bushes/rocks.

There isnt one coil that will do everything so you have to decide what feature gives the most advantage and go for that coil.

I also have the 14x9 Evo (as mentioned by Nenad) and its great for smaller prickly bits.

      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?

      Hi all,
      I've done up a video comparing some of the new coils.
      I'm an agent for Detech coils, but tried to be as unbiased as possible.
      Be interesting to hear your thoughts on the results.

      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.

      So this Saturday im heading back out to the property that produced 4 nuggets with the GPX 4800 last time, using the 11 inch coiltec elite.  
      The area we will be focusing on has mainly been known for producing larger nuggets in excess of 5 grams.  My question is, is there any advantage to use the 11 inch coil vs the 15x12.  
      The 15x12 obviously gets more ground coverage but  would think the two would be about equal on depth to larger nuggets.  The 15x12 is probably less responsive to smaller nuggets compared to the 11 inch.  
      Which would you use on ground that was just clear cut with targets that will generally be on the order of 5 grams or larger?  
       
      Thanks for the help

      I was wondering if the aftermarket coils were that much better than the Minelab, i.e Coiltek.
      I'm very hesitant to go Coiltek because the GPX was designed to use only Minelab coils?
      My fear is i don't want to hurt my GPX 5000 in the long term by putting a coil on it that Minelab doesn't like?
      It seems like everyone with a GPX is using a aftermarket coil. I especially like the Coiltek 9" Elite
      I'f you were me would you get a Coiltek coil?
