Puzzled By GPZ Detecting Tiny Nuggets Deep But Missing Shallow Shotgun Pellets
I have ordered a new size X-coil, it's a 12x8" X-Coil, It's already in the post however it's delayed in shipping due to international shipping delays the world over. Hopefully this coil arrives soon. I am very excited about it as I think it will be the perfect size for NZ.
It's even in NZ's black and white colours.
This should be good in our rocky terrain on small gold.
I'm not shy about it. Yup. I have big clumsy feet. The good news is it gives me stabilizing ballast should sobriety forsake me. The bad news is it's hell on GPZ 7000 lower shafts. I have broken several. To make matters worse, the lines of communication between my big feet and my small command and control center often get disrupted somewhere between my gullet and my gizzard which allows my big feet to proceed on a different heading than the rest of me. Oops, there goes another GPZ 7000 lower shaft. But I don't take full responsibility for all of these broken lower shafts. I don't recall ever breaking the good ol' GPX lower shaft and they fit at least 10 different detectors and cost less than half of a GPZ lower shaft. So I lay most of the blame at the feet of Minelab and not because of the feet of Klunker. The shaft is just plain flimsy.
Being a "tight wad" by nature I have tried numerous times to repair a broken lower shaft using glues, epoxies, tape, splints and every flavor of bubble gum you can imagine. Nothing worked. I finally came up with the idea of totally replacing the lower end of the shaft and it work splendidly.
This was made from an inch and a quarter by 1 inch pvc plastic pipe tee, a fine toothed saw, a drill, a round file, a sander, a heat gun and a bit of good epoxy.
This repair has held up for a couple of dozen trips and survived the icy conditions of early spring detecting, which is when my big feet are at their worst. If anyone is interested I will post instructions
Why oh why does the WM12 take such an unusually long time to recharge when the GPZ battery charges in a couple of hours, and other electronic equipment charges in (much) less time than that? I am not actually complaining but I am very curious why this is so.
Today I took a short beach swing and didn't find much but it was good to just get out in a sea breeze if you know what I mean. I used the Equinox 800. About midway through my 2+ hours I checked my settings and noticed I had recovery speed on 5. I changed it to 6 and then the thought came to my mind, "What would I do or could I do with the Zed to immulate changing the recovery speed?"
I've used the 800 in many different settings so far but mostly the beach. I've seen the videos of nails next to good targets.
How do YOU tease the good targets out of trash like the 800?
JW contacted me in the morning saying he's got the day off work so if I wanted to go for a detect jump in my car and head on over to his place. This is always a hell yes from me, the world would have to be ending to stop me.... oh uhm... whoops 🙂 maybe more than the world ending.
We were going back to the exact same spot we were at the previous mission so figured I'd either use the 15x10" X-coil or the 10" X-coil, but because the area is very rocky I went with the 10", you need as small of a coil as possible for this terrain.
The 10" can get into some pretty tight spaces. Gold here would be missed with any bigger of a coil.
JW noticed our Davsgold picks looked a little different, this is odd as we both have the same pick so we compared them
The years of wear on JW's pick is pretty evident, his pick has gone through hell smashing up schist for years 🙂 He needs to give it a sharpen, the sharp point on mine is very handy.
I've also upgraded the magnet I had on my pick, it's been excellent. I drilled out a 30mm deep by 20mm round hole in my pick and dropped the strongest magnet I could buy into it with the same dimensions. Now not only is the base of my pick magnetic, the sides are too, it sucks up ferrous junk like mad. I'm very happy with it.
I can move the black sand around on it 🙂
JW was back detecting his highly productive cliff edge armed with his hammer and screwdriver, so I figured I'd go back and check around where I was the other day.
It wasn't long and I had a very faint signal, a few scrapes and the signal improved. The bedrock in this spot is about 4 to 9 inches down. It turned out to be quite a nice bit of gold down in the bedrock that required breaking up some bedrock to get to it. For the first time I managed to record a good part of the find on video as I was so confident it was going to be gold. I've wanted to capture a find on video for a long time.
Here is a photo of the spot I got it, it was actually quite deep, and the gold was on edge, it's a very skinny bit.
My biggest of the day.
I spent the next hour or so checking the area slowly. Plenty of pellets but nothing else.
I moved back down towards the little gully JW was detecting and on the path we bike in I had a signal, I'd done this path bit the other day with the Nox, I'd spent an hour or two on this small area with it but I missed this piece, maybe just too deep for the Nox.
Down through the gravels to the bedrock again.
Almost like a little ball 🙂 This round gold is common in this spot, JW's been getting a lot of it.
I then realized I forgot to balance to my ferrite ring, seeing I'd gone from the 12" to the 10" X-coil I thought I may as well do it.
Again I don't know if I am balanced to it being new to the GPZ but I did the procedure and the noise of the ring all but disappeared after a couple of sweeps over it.
The day was getting pretty exciting, I was hoping for a 3rd but for the next few hours I got nothing but pellets... I had a break and drink and watched JW for a while, I usually learn a few things doing this and I was able to see his coil control is far better than mine, he drives that thing around keeping it so close to the ground hugging the rocks while checking the bedrock cracks.
The cracks in the bedrock like in this photo can contain gold, but you have to check the entire rock as the gold has proven it can be anywhere in the rock in healed over cracks.
As the day was coming to an end I went over to a spot that chased JW away with the abundance of pellets there, they were everywhere!!!!
It paid off though, my final nugget for the day
This is up on a bedrock ledge, the ground is 10 to 15 feet below where this little ledge is
and down deep in the gravels was a bit of gold........ and about 8 pellets 🙂
The gold had a louder and more distinct signal than the pellets. Another ball type bit.
And now the weigh in.....
Not as bad as last time, I'd already done a lot of the cleaning of the area 😉
Not too bad 🙂 I haven't had three in a while. Almost worth celebrating with a beer at the pub
