Most Effective 19 Inch Coil Cover

Recommended Posts

 

opinions welcome regarding the "best" coil-cover for the 19 inch.

I don't like the stock cover-but, that was a forgone conclusion..

I am not sure of the choices or durability of the manufactured items...

I think the lexan is durable but...................more weight on a heavy coil.

I will say that using the 19 inch makes the 14 seem a featherweight...in comparison.

The weight of 0.8 or 1mm thickness of lexan is less then the available coil cover even combined with the silastic adhesive, the big advantage of the lexan is because you adhere it to the coil it stiffens it up considerably. This leads to a coil that is not affected much at all by knocking rocks, ground, trees etc. Of course if warranty is a concern this is probably is not the way to go. I now am replacing all coil covers as they wear with this mod. With nearly a season behind this mod on the 19 & 14, is the way to go for me. Wish Phoenix had told us about it 30 years ago.:wink:

A warning ensure you get Lexan or poly carbonate not Perspex, Perspex cracks splits and is just not suitable.

Hey Fred.  The 19" coil is the first coil I haven`t glued the lexan directly onto the coil. It was my intention to remove the original and slap the lexan directly onto the coil, but when I saw the pottings were exposed on the coil I glued the stuff to the original, so I`ve got the weight of the original skid plate plus the Lexan, but as you have pointed out the coil is so heavy anyway, I think the increased weight is three fifths of five eighths of not much.      I think Norvic could be onto something about the increased stability of the coil as well.   My coil is not bump sensitive and neither is Norvics, but some people have reported their 19" coil is bump sensitive.  I`ve got 1mm but Norvic says 0.8mm, so if you can get 0.8mm that`s even better.

Yeah, went looking for 1mm but Hardware store had 0.8 in stock, so went with it, have done many hours on 19 this season just love it. But make sure it is Lexan you get, Nurse Paul had what he thought was lexan adhered to his 19 but it is only Perspex. Took me bloody hours to convince him he`d been conned........:smile:

I have the Nugget Finder cover and it's ok, but I wish it was a little thicker for the price. Not much meat there and it will wear through rather soon I think with the big coil riding on top. However, it fits well and I figure I can then glue something to the bottom of it if need be, instead of glueing something to a very expensive coil.

Is that the same as the Nugget Finder one Rob sells Steve?

thx

It is and thank you Jen for pointing out I used the wrong brand name - error corrected. Yes, same one Rob sells.

Sorry Steve but this is slightly off topic but does involve the 19" coil. Do you use the 19" very much, how do you find it (& I dont mean you open your eyes & there it is:biggrin:) have you been finding gold at depths that you think the 14" wouldnt have got? I know that last question is a bit of an unknown without actually swapping coils. Cheers.

Good luck out there

Hi JW,

My one report on the GPZ19 so far is at 

It did get me one nugget on that outing I missed with the GPZ14 but did I miss it because it was too deep - or did I just miss it?

My gut feeling is that as is usually the case nearly all gold a GPZ19 can hit can also be hit by a GPZ14. I have a suspicion, unfounded, that the best depth gains will be seen on the kind of gold that the GPZ favors anyway - porous and specimen gold. So that big coil I am guessing will get the best results on large specimen gold as opposed to solid slugs. For me this is a niche coil for oddball situations, not for constant use, as most of my gold tends to be under 1/4 oz and as a rule not really deep. However, I do have a site in mind for my very next outing however so we will see. Just another item I am learning more about over time. I promise I will have more to report in the future. I am juggling too many detectors right now (Impact, Deus HF, GM1000, etc.) which kind of drags things out as I bounce from one idea to another.

I think I sense a hidden question here. What about this coil for you? I am seeing small shallow gold so other than ground coverage I can't see how this coil can help you much.

      Does anyone have a vid link to a nugget going low-high (filmed after the update only) that shows how deep it was and how big the nugget was?
      On nuggets up to 40 grams I still cannot get a low-high signal with just one exception and that is squirrly little wiry or thin flaky pieces that flip between high-low and low-high, and with some regular pieces when they get really close to the coil they will flip between the two as well. 
      I had a 65 gram slug of solid smelted gold and it was going high-low on the GPZ. It was low-high on my 45 though.
      What I'd really like to see are the types of gold that are low-high from beginning to end, no matter how far from the coil. If anyone has some links or has such a nugget and could toss it on the ground and film it I would be very grateful.
      One reason I'm wondering (ok, don your tinfoil hats) is low-high is so often iron now that I can't help but wonder if discrim might be possible with ZVT tech and there may be some kind of "discrimination update" coming in the future.
      Also, bonus question: can anyone show me a case where General is outperforming High Yield in depth and sensitivity and what exactly the type of gold (weight/sponginess/etc) is that causes such a thing to occur? Or ground type if that is causing the difference. We see it on the ML chart (or it would appear that way but we don't know for certain due to omission of actual sample defintion), but I haven't found a case with my gold where it happens yet so I'm curious what to look out for or if I should just give up on going back with General after HY unless I have gold past a certain size threshold.

      Hi guys, I have done a goggle search on this & have come up with nothing. I thought I saw an article on here about it but a search showed nothing here either.  I thought there might have been something printed on the box to help out.....but no.  Is there any thing I need to know or is it all pretty easy really? Thanks for any help or advise.

      I've been back to 5 old patches with the new detector but I'm limited with a health condition as to how long I can swing the detector but It might be up to 40% less   I've got about 20 more old patches to re-hunt that will take many more days.
       
      So far I've picked up 6.2 dwt's that were missed by several other Minelabs and a gold bug II and different operators over several years of hitting the same patches.
       
      I don't think I need to say much about the detector because the testers Steve, Chris, and JP have well written reviews about the GPZ . The biggest nugget so far is a .8 dwt and a .9 dwt nugget. I'm still waiting for the bigger gold....   but in all fairness to the GPZ the ground is mostly deep where the big gold was found and I used big round mono's up to a 25" nuggetfinder and a 24" Coiltek to find the big gold.

      Hello All,
         Just a FYI, make sure you understand the settings and what is working best.  I just realized the first day out, even though I found 8 nuggets, I was running settings that were no better than the GPX 5000 after some further testing.  What I would consider a large nugget, the GPZ considers it a "small" nugget, which is best for High Yield over General.  
      I also realized "Difficult" soil really makes the unit purr, but takes a lot of performance away on the ground I was hunting.  I was trying to find a happy medium from a noisy Normal to a Difficult soil setting with a higher gain.  
      Experiment is the key.  What I originally thought was good, wasnt .....

      That's very strange... unless he tracked out the target by pumping the coil?
