First Gold With The Gpz (and Drowned My Xcoil)

Recommended Posts

I guess the same has happened with the Equinox, how many stories of drowned Nox's are there now and it's got quite a good waterproof rating in depth.  I soaked my Nox at over a meter depth in my Spa for 2 days to be sure it's water proof while it's still under warranty.  If it's not necessary to put things in the water it's probably best not to.  When things have a low limit like the GPZ with 1 meter depth limit on it's Minelab 14" coil I guess there is always a risk, if something said 10 meters waterproof or something like that I'd be less concerned.  There is no way in the world I'd put my Minelab 14" Coil in the water, not that I'm likely to ever use it again anyway.

If something says water proof to 1 meter depth like the genuine Minelab GPZ coils I take it as it's water resistant more than water proof.  The only true waterproof coils I think are the epoxy filled ones like Nel makes for the VLF's which incidentally have no depth limit, the limit is dependent on your detector not your coil.  A GPZ coil would be to big to epoxy fill, it would get far too heavy, you'd need wheels on your coil to move it around 🙂

Something to consider with regards to water proofing, cutting the coil lead and adding a new connector might then allow moisture to ingress the coil via the lead (especially the leads cut before the curls), the GPZ14 coil is over moulded both ends as part of the waterproofing of the assembly, dependant on where the cut was made could be the reason for the OP’s fail.

Good point JP, I was talking about this exact thing with Nugget Hunter when he was working out what adapter type to make, although the cut before the curly cables makes an adapter easier to make he went with the short version of the adapter that is up near the control box so a long way from the water as he was hoping to silicone up his coil to make it work in the water and keeping the adapter well up out of the water was a consideration.

He was going to get his electrician friend to make his adapter but then he had the detector and coil sitting there and looking at him so he went ahead and made it himself 🙂 Excitement took over I guess! He did a good job of it too.

Fortunately his coil is working again now and it dried out quickly so only a bit of water got into it.    The 14" ML Coil is working again now too last I heard so he was lucky.

A friend has used the spray on truck bed liner on his coils and has never had a problem.

That stuff is tough and if put on properly it will never give a problem again.

Hope that helps after your unit dries out.

Yes....they are not waterproof.:rolleyes:  I did make mention of this as a warning to nugget hunter nz (Craig) on his post on making his own adapter for the X coil/Zed. I repeat it here.  "On a personal note....I will never be putting my Zed coils in water, but the areas where I mostly detect there is no water up in the hills any way. I even hate using my detector out in the rain, of which the other day out with Simon it was raining most of the time. I shouldn't have gone. I wouldn't have normally but knew that Simon was eager to try his "new" set up. After a few hours & 4 bits of recovered gold & two lost ones I had had enough & called it quits as I reckoned the detector was starting to act a bit weird. I didn't know at the time that Simon had text me to say his back was giving him grief & he had had enough to. I didn't take my phone with me but must have timed it right when I caught up with him. I put it down to the coil getting drowned as I have a good cover on the actual detector control box & the handle pod. I honestly don't know how the coil can be waterproof with that pressure vent valve.  The guy I got my Zed off is from the West (wet) Coast & he killed his ML 14" coil detecting in West Coast creeks. It was warranted as being waterproof so Minelab replaced it under warranty. The West Coast & its weather is not very detector friendly. I am not prepared to risk it. My thoughts always were that the ML or any 14" size coil of that type construction & design ( foam filled) is a beast of a coil to try to subject to using underwater with fighting the buoyancy & water flow." End of quote.

But what would I know?? Hopefully Craigs coils will dry out with no ill effects. He now knows not to put them in water. Learnt the hard way. Warning for others so thanks Craig for bringing it to peoples attention.👍

Good luck out there

Yip defanitly my fault not any of the coils i know the new nugget finder coils are waterproof and they are releasing a small coil mid year with more to follow. 

I guess if I hold out for those and try it if that doesn't work then guess I'll have to sell the zed go back to gpx modded with the nf coils I never had any issue with those and water the zed is amazing just wish it was more water friendly 😂

So does the coil simply stop work with water ingress?  I have had mine in water a few times, probably around 20 cm, no obvious problem from water.  I do have the issue falsing when knocked but expect this is not water related.  Out of warranty unfortunately.

No no didn't stop working just started going crazy like sevear EMI with target like overload spikes if you held the coil still and flat it would sort of settle down but any change or angle or coil movement sent it nuts... I did dtill find gold with both after taking on water but was only booming obvious signals

Nugget Hunter NZ,  Very good video and nice dense solid pieces of gold too.  Funny how we can drop the F Bomb when excited.    "Fu Me" as if I'm hoping some gold goddess jumps out of the bushes.  Raw and nature video is the best.  I've done the same on occasion and it usually is when I really nice or unexpected find is dug up.  Thanks for also confirming the coils and their abilities and or lack of.

Prevention is better than cure. IMHO. Foam filled coils, to my tiny mind, are not the best for using under water. They need to be of an open spider web construction & epoxy filled to lock the wires in place, protecting the windings from any water that may get in & give the coil a bit of solid weight to lessen flotation ability & to lessen the impact of flowing water. Just like the platypus coil that Coiltek made for the Minelab PI's for using under water.

      According to the Minelab website, the GPZ 7000 is "weather proof" meaning you can use it in the rain.
      The GPZ 14 coil is waterproof and submersible to a depth of 1 m (3 ft). You can easily detect rivers and shorelines with no fuss! The weatherproof design of the GPZ 7000 allows you to go detecting in rainy or wet conditions.
      This seems reasonable, it looks that way except the headphone socket on the back of it, in the worst possible location to fill up with water as your coil is on the ground pointing that socket straight up to the rain.  The other day JW and I were detecting in the rain and I couldn't help but notice the rain drops landed on the back of the GPZ and the water drops run down into the socket.  They just kept dripping down into that 6.35mm socket and it had me worried.  Over time I could see quite a lot of water getting in there, eventually it would fill up.
      I ordered a cover for my GPZ, while it's great for protecting the screen it doesn't cover up the back of the GPZ, leaving that same socket exposed to the rain.

      The designers of the cover did a good job on the screen and control box but the back is wide open.

      You can see the exposed socket there, no protection at all from the cover.  I'm never in my life going to use that socket so I went on the hunt for some covers for it and found these things

      They just push into the socket and have a little lug to be able to pull them out when needed.
      Has anyone bothered with this sort of thing? Is there a need to? I ordered a lot of 10 as they were cheap anyway and I can put them on all of my detectors with the 1/4" sockets as I never use headphones and it's such a big hole for water and dirt to get in.
      You can get them at Amazon and various other auction sites and electronic stores.

      Found a nice little run a couple of days ago, 2 days in a row just over 1/2 oz  each day and another 23 grams this morning.
      Here's a pic of this mornings total....

      I don't film many digs anymore, but the bigger chunk had a bit of depth. I was hoping it would be deeper and bigger...but alas, not to be, it went just under 10 grams

      Well, I tried a new way to get out to this new gold area I found.  The gold seemed fairly small, but I had to hike in at least 3 miles to get there.  So I tried to drive in another way in hopes of only having to hike in a mile.  Of course Google Earth made things seem better than they were (almost like I could drive right there), but in the end I only cut about a mile off the hike (one way).  So now I had a decision to make … take my GPZ 14" coil, the GM1000, or what I call my Midget Coil (10" Xcoil).  GPZ 14" about killed me getting out there last time so that was out.  I love the GM1000 on bedrock, but some of the bedrock here was very hot.  Usually in those cases, I will go to my GPZ 10" Xcoil, which I venture to say is at least on par with the SDC 2300 (with the exception of being a little bigger).  And the Xcoil is still a pleasure to hike with.  So off I went.  
      I started out hitting the areas I had been to before and got some good signals.  First piece was only about .1g.  Then I started finding slightly bigger .2g pieces.  Most of these seemed to be what I call runners.  Those are the ones in washes that I find on the sides of the wash, trying to run away when they see me coming.  The larger coils tend to lose a bit of depth when checking the sides and depressions.  The 10" Xcoil, however, does very well getting in there.  
      Overall, 5 pieces were found (total .75g).  Not a lot, but at least half of these finds were detected very carefully with the 14" coil and were missed.  The Xcoil was very clear on all but a 1 grainer piece that was about 2" deep on it's side.   All in all, it was just a fun day crumb chasing.

      I had my first outing with my GPZ about a week ago with JW, my back was still terribly sore at the time from an injury so I wasn't really doing well and had trouble digging targets, and we were in terribly heavy rain so I was off my game.  I went back to the same spot today, the weather was much better, in fact it was far too hot for me.  My back has improved a lot, I lasted about 3 hours which I thought's pretty good, my longest detect since I did my back in.  This particular place I've always called my Nemesis as I could just never do well there.  I've been there probably 25 times and only found gold three from memory.  The first time with my Gold Bug Pro which was 1 bit, then the QED with 12x6" X-coil which got 1 bit, then the GPX with 10" X-coil which got 1 bit.  I've never got a bit with the Nox or Gold Monster here even though I've used the Nox the most I'd imagine and I'm the most comfortable on it feeling I can use it pretty well.
      I had a lot more faith in myself today as JW has done very well here with his GPZ and 10" X-Coil so now we were both driving the same machine surely I could come away with a piece.
      I threw my little ferrite super magic ring on the ground and waved over it, no response unless I rubbed the coil on it so maybe I don't need to do that anymore after doing my Quick start procedure the other day so I just got stuck into it.  I've had a few skilled operators suggest I use Manual instead of Auto or Semi Auto, that made sense to me with our mild soils here so I was in manual, I raised and lowered the coil and had no response from the ground so I assumed that I didn't need to do anything so I just got stuck into detecting.
      I first tried all the mountain goat one gust of wind and you're dead terrain, I get a bit wobbly detecting this stuff as I'm not so good with heights.
      My first target was a shotgun pellet.... not unexpected, there are many of them around here....

      That's good though, it means the detectors working well 🙂  I'm not used to the target noise of the GPZ on these small targets yet, bigger targets sound similar to the GPX but these small things behave differently, it's sort of a wobbly noise, different to the GPX.
      I kept going, detecting closer to the cliff.....

      Scary!  I did get a target in this area, it wasn't on the surface as it remained after my first scrape and moved on the second, unfortunately, a tiny little bit of some sort of junk

      I was super impressed with the sensitivity of the 12" X-coil getting these tiny little targets, Gold Monster size bits of junk.

      I really thought I had a nugget in this photo above, this was just before my dig..... turned out to be another shotgun pellet stuck in the schist bedrock 😞
      Now the sun came out, it was terribly hot and I was frustrated looking at the nice cool water below me while I'm up here sweating badly wanting to jump in it to cool off, I really struggle in heat so I moved away from the cliffs and jumped in my car to go back into the terrain JW found his bits last weekend, it's very close by and I could have walked if it wasn't so hot and my drink had run out already 🙂
      This next area has lots of good bedrock and didn't seem as junky with the pellets, the issue here is the power lines, I dropped my gain down to 14 from the 20 it was on previously so the machine ran nicer as I couldn't put up with the power line noise as the spot with the bedrock I wanted to detect was basically under the power lines.  As I detected further away from them I cranked my gain up again and as  I got closer lowered it down, quite easy to do on the GPZ as you just leave it on that option and adjust as necessary.

      Why do they always put these right where the best bedrock is... I'm sure they did it on purpose. 

      Nice bedrock though... I could see a number of fresh looking dig holes around, I suspect JW's handy work, he was good though, all necessary ones were back filled. 😉  The funny plants are getting annoying, there is a plant that looks like that if you grab onto it and try rip it out it spikes you to death so I wasn't game to touch them, just worked around them.
      I noticed an area with a lot of dig holes but it was virtually right under the lines, I figured there is no point doing that area but the dig holes seemed to go off in a direction so I instead went down rather than follow the digs and it was only 15 steps from a dig hole and I had a target, quite faint but very obvious.  At this point my gain was on 12 to calm down the power lines and I had the detectors volume on 4 as the Steelphase SP01 was attached to the Wm12 and gave me all the volume I could ever want.  I did notice if I got between the WM12 and the detector sometimes the audio dropped out for a few seconds and picked up again if I moved, it seems it doesn't like passing the audio through my body, is this normal or is my WM12 a lemon? I would think it's pretty normal passing wireless though your body.  I tried changing frequencies but made no difference.  I might just use my Quest Wirefree mate as it doesn't seem to do that, similar thing to the WM12 anyway.
      I dug the target thinking it's probably going to be another shotgun pellet, it was doing the same wobbly type noise, hard to describe the noise....  I did a scrape with the pick and it was still in place, getting hopeful but the bedrock was quite shallow so I just started taking scoops out with my plastic scoop and waving them over the coil, narrowed down a target and it was a bit of gold! Awesome, my first GPZ gold, a tiny little thing....  I rechecked the area and the exact same noise was still there, it sounded like I never even dug the target.  So I kept scraping it out and waving the scoop over my coil, a few more scoops with and I had the target. Boom! Another bit of gold.  Two from one hole! this doesn't happen to me often.

      The spot I got them!

      You can see the detector sitting in the spot still where I got them and if you look up the damn power lines!

      The two little guys! 🙂  I was done for the day now, it was too hot and my back was pretty sore.  I had a goal of finding a bit of gold then I was going to leave, it's lucky it happened when it did as to clean the little bits I had to use the last drop of moisture in my body, my spit came out like pasty thick molasses to clean them.  I stumbled back to my car and was lucky.  I found a few fruit trees on the walk that were covered in fruit.  I got my fluids up eating a bunch of apricots and a few plums.


      I picked a few for the road too

      Washed down my KFC with them.
      Time to head home, my wife had sent me a text message while I was detecting saying I've had a parcel arrive, it was the two coils I've ordered to start exploring for some new ground, I wanted some ground coverage so I can explore and find some ground JW hasn't already done so I think this is partially why I called it quits so early in the day, I wanted to rush home and see the new coils 🙂


      15x10 and 17x12"
      I've tested both of them out already in my backyard, both detect my bits of gold I found today, that means they'll be my perfect exploring coils.  I hoped they'd both still have the sensitivity to small gold which they do.  I shouldn't say my bits of gold either, my wife confiscated them off me, valentines day gift she said as its valentines day here today 😄  It's the first nuggets I've given her so that's OK.
      Time for the weigh in.


      Not too bad! Happy with that.  I really like the 12" coil, it's going to to be my everyday use coil.
