Nugget Finder 12" Round Vs 12x8" Elliptical


Recommended Posts

Hi guys I was wondering if anyone out there could tell me what ones best of these two coils I've herd alot of  good things about the 12 round nugget finger coil but like the eleptical coils as can get them in places the round won't go and I know the 12x8 is fairly new .but thought I'd ask if anyone has any experiance with it compared to the 12 round ..on depth and sensitivity?

  • Steve Herschbach changed the title to Nugget Finder 12" Round Vs 12x8" Elliptical

Hi All,  I've been loaned a 12 x 8 Evo coil to compare with my 12" Evo round.  I placed 2 pieces of gold in the ground, an 0.6gm nugget at 6" deep and an 0.04gm piece at nearly 3" deep ,  both targets I could hear with the 12" round.  With the 12 x 8 I could hear a very faint signal on the 0.04gm piece.  The o.6gm piece I could not hear a peep out of it with the 12 x 8.  So I did not buy the 12 x 8.  I must say that the 12 x 8 was not the latest production model, it was a prototype model coil, this was done with my GPX 5000 in fine gold in VIctoria, Australia.  Cheers,  Hermann.

Hi All again,  Somebody was not happy with my report on the 12 x 8 Evo coil.  However when I get a chance again to try a 12 x 8 production model I will try again, and as I wrote, the coil that I tried was just a prototype, and it may have been abused. Cheers Hermann.

Steve,i own and use a 14x9 Coiltek mono coil on my TDI Pro the main reason being that is ultra lightweight and i do suffer from a wrist problems,hence the main reason i use it,i also have the stock 12'' DF coil that comes with the TDI but not used it very much,so do you think the stock coil would give me slightly more depth ??

Another coil which i also have and will be using over the coming winter months also on the TDI is the 15x12 Commander mono coil,albeit it is heavier than the other 2 coils but being physically bigger i would have thought that the 15x12 should be deeper out of the 3 that i have mentioned.......i do have much bigger coils but those would be predominately use on very special occasions say on deep pasture for large artifacts and hoards.

Your input would be most welcome

Hi Rick,

I think you hit on an important item - physical capability. While depth is all fine and dandy, we are not talking double the depth or anything crazy like that. Going to a larger coil at best you usually just get that extra inch. That being the case I like a coil I can swing for 8 hours without killing myself. I personally really like the 14" x 9" form factor as a good compromise between depth, weight, and ground coverage. The 15" x 12" Commander mono was a very good performer back in the day but some of these new coil windings may have an edge that negates the size difference. Not having used the newest coils myself I can only suggest what I would do myself - a half day of comparative coil testing. I can't imagine there being much difference at all between the 12" round and the 14" x 9" as regards performance so it really just comes down to which coil you prefer to swing.

My old 14" x 9" Nugget Finder helped me score a 6.5 ounce gold nugget so you can see why I might be fond of the coil!

I had the old Nugget Finder 16" round super light mono coil at one point. The old housing design but that was a sweet coil both for being light and deep. Unfortunately it started getting flaky and had to be retired.

Steve,some tremendous information,think i will stay with my Coiltek,its the only coil that really suits my sites,as the coil is foam filled it really is ultra lightweight,as i dont use it everyday i even use it without the coil cover on like all my coils and suprising how heavy a cover can be especially on a very large coil.....cannot exactly quote the weight as i have never weighed one but my large 20'' Jimmy Sierra coil coil cover weighs alot and i can only swing that setup using a GPX full harness and the amazing hipstick,but i can swing the Coiltek 14x9 mono coil all day.

Thanks again for your input,will be using the 14x9 coil this coming weekend on a very old pasture site.

I found Elliptical coils were best for ground cover when the target is a strong signal.

That is 14" x 7" coil  will give you about the same penetration as a 7" round coil and a similar ground cover as a 14" round. If the signal is very soft (very small target near the surface or very deep good signal were you have to over lap your swings a round coil wins hands down. ). So a correct size elliptical for patch hunting an a appropriate size round for working a patch.

You forgot the magical part of the equation, the size of the target! 

I recently tested a 0.1g prickly piece of gold and the 12x8" got it deeper than the 12" by a good margin.

Just the person I was hoping would chime in, do you think it's worth me getting a 12x8 when I have the 14x9 Evo?  Keep in mind almost all the gold in NZ is small gold ?

The 14x9" is no slouch. In the testing I've done so far, if you can run a high gain on the 14x9" it will pretty well match what the 12x8" can do, especially if you can run Sens Extra. 

In hot ground it's a different ball game. Where you are forced to drop your Rx Gain, the 12x8" retains a lot of sensitivity, where the 14x9" starts to lose signal sharpness a lot earlier. 

Interesting thing though, on this 0.1g bit, Fine Gold was the best, provided I kept a slow steady swing. Sens Extra was next best, followed by Enhance which struggled a bit. I've seen this scenario several times in the past, which is why I still have the 5000, even though I have a soft spot for the old 4500. 

I also tried the 15" Evo just for kicks. Sens Extra was the only timing that got a sniff on it, but I had to up the Gain and back off the stabilizer. Fine Gold and Enhance nothing. 

In thick scrub, the 12x8" is nicer to use.

      Hey I was wandering If anyone knew where I can buy or get a coil connector plug for my equinox I just broke it very frustrated.

      Seeing how this topic has numerous mentions across the internet, what are the range of faults exhibited? My nearest dealer is over an hour from me so I don't want to travel back and forth after picking mine up if I get a faulty one. So I know what to look for after collection and field test. 
    • By oldcoinhunter
      My first 6000 was faulty out of the box which they replaced with a new one. I've had the new one for 21 days and probably used it 8 days before it went bad.  When i was boxing it up to ship back i heard something rattling inside of it, not good. In researching i found that they've known them to have major issues since March or April, yet they have refused to address the issue with a production stop or at least look at the different production runs and recall those units. I think when it's all said and done there will be a substantial number of them that are faulty worldwide. As it stands now, Detector Center states that there is a" temporary" 10- 14 day time frame for repairing them. My bet is that it's not going to be temporary. If this failure rate continues there may be grounds for a worldwide class action lawsuit, who knows. Oh, and i owned a business for 40 years. Not a very smart way to run a business. JMO.

      Well my staff/I just finished the season and wrap up of field training for 2021 and our customers...and boy did it go out with a bang and big belly's thanks to Chef Rusty Bucket.  Smoked ribs, Bourbon shrimp in garlic sauce, berry pie and ice cream, smoked Brisket, bacon wrapped stuffed jalapenos and more.  Wish I would have taken more pics of the food.  As I have said before, the food/drinks/people are part of why I enjoy these trips, as I know the gold will eventually come.
      As many know, Gerry’s Detectors has been training out there at the burn barrel with a few different staff members since the 90’s.   We have been using just about every model of gold detector from the top manufactures as well as coils to see what the best results are.  The comparisons of customers detectors continue to see the improvements of technologies and capabilities which is what we want.  Yes there are times a more expensive detector may not produce the best signal response on that particular targets, but it’s what it is and part of learning.
      Some of what we found most amazing and it’s exactly what I expected would happen during the training at RP.  The gold nuggets being found during the 3 days of class was the most of any session in at least 5+ yrs.  More people went home with actual Rye Patch gold than what my staff/I have witnessed in quite a long time.  The knowledge shared was the same stuff we always go over, but the knowledge retained was higher.  The class size is usually around the same, but the amount of golden smiles of success was better than many yrs prior.  We know the VLF detectors when fit with small coils are going to find a few pickers, but to see the bigger PI machines perform so well and produce such higher %’s of beautiful NV gold was most impressive.
      So lets go over it again to see what my Staff/I observed, in no particular order.  Knowledge of customers detectors was actually retained, smiles of happy customers making the right choice of detectors, the amount of successful customers who went home with gold and the overall numbers of gold nuggets dug by the students.  There is one thing that I corollate all these positives and it’s the new GPX-6000, period.
      Yes we had SDC-2300’s, GPZ-7000, GPX-5000’s and the usual VLF’s in the class being learned by the students and those who were there with the GPX-6000 had the most Success.  But the success of gold nugget finds was just part of the fun.  Ease of operation and simplicity we’ve never seen from a PI Minelab was also most impressive.  The customers were actually not afraid of their detectors.  They didn’t worry if the timing and or sequence of adjustments was correct, as the GPX-6000 is pretty much a turn on and go.  The old way, a big multi page instruction manual (is missing) and now we get a 3 step Quick Start…and it’s true.  1) Turn On.  2) Raise/Lower Coil for 10s, 3) Begin Detecting.  Are you kidding me, no way that can’t be true.  We just paid $6000 for one of the latest technology fine tuned gold detectors in the world and all we get in the box to help learn, is 3 short steps with a combined total of 10 words?  
       
      Well folks,  it’s all true and so is the amount of happy customers who invested in our training and the new GPX-6000.
      If anyone thinks there was some other reason for the above, please chime in as all indicators are bulls eyed at the GPX-6000.  Overall the trip went exceptionally well consider the 100 yr rain storm that came through while we were down there.  I still love the natural beauty of Northern NV in the fall and the colors on the gold nuggets we dug.
      Hopefully the Spring/Summer class will be just as productive with a group of new enthusiastic customers and more gold being unearthed.

      Hello All,
          The new Minelab 17" Elliptical Searchcoils for the Minelab GPX 6000 have been flying off the shelves, definitely high demand.   Due to the high demand, I haven't had much time to use one, everyone ends of taking mine ... LOL
      I haven't seen much larger gold being found at depth yet, but I'm sure it is.  Curious how people and past customers are doing with this new 17" Searchcoil beyond covering more ground quicker?  
      We still have a few left in stock from the last large shipment and more on the way if anyone is still searching for a new "Christmas present.!"  Hahaha 
      Would love to see some pictures or at least hear about any success with the new searchcoil.  
      Wishing you all much success on the goldfield.
      Rob

      Each time I try and ground balance my 6000 there is no detectable change. While holding the GB button I pump the coil then move it side to side. It’s like it don’t work. I friend of mine says his does not either. What am I missing? I run in manual mode with the threshold on. The noise cancel works very well.
