My daughter had a friends party to go to this weekend, it's currently a long weekend not that it changes my life but it means a lot of people are off on adventures and doing small breaks, I figured seeing I was going to be right near the beach to pick my daughter up from the party I'd take my detector for a quick hunt. I only had a couple of hours and I didn't think I'd find much, although I think it's a nice beach it's not overly busy and as we are just in spring the hot beach weather isn't quite here yet, although today was 25 degrees celsius which is 77f in the old money so it was pretty warm. A few surfers were out but not much in the way of beach goers hanging around on the beach which was good.
I had my pooch with me as he seemed to be itching for some time away from the house but my wife mostly looked after him, he came and did a bit of detecting but he was just getting in the way.
I parked near a giant concrete whale for a look around then moved on, the area didn't look like a good detecting spot, too many people around for my liking as there was a playground nearby.
A bit further along seemed alright, parked down near the beach but had to go exploring the hill to see what was about.... my dog dragged me up.
the beach is covered in pebbles and shells, it's also typical of a New Zealand beach with a lot of black sand, the Nox was a constant -9 on the entire beach. I was hoping this big bit of drift wood might have something under it from people sitting on it, but there was nothing..... I also wasn't finding any junk anywhere. I was wondering if my Nox was just struggling with the black sand. The ground balance was fine on it though, it wasn't an issue unless I went to all metal then it was always -9.
Next Stop! Antarctica!
I found I had to ground balance a bit as the concentrations of black sand were pretty obvious.
I did a bit more explorirng and found an area that looks like the tides go into it moving the sand around.
and had my first good target in the bottom channel of it.
Not even sure what coin it is 🙂
My next coin was in a similar area further along, I wasn't overly gridding or doing anything fancy, just walking along exploring.
This area looked like the water had washed it out, like sluicing from gold miners 🙂 I have no idea how to read beaches, I was probably more thinking prospecting than beach detecting. You'll notice all my dig holes in the above photo, all coins.
Often quite deep too ,and all old, no modern currency all coins from some time ago.
an old Shilling, not sure if it's silver but very likely as most years of shillings were. It's ID was right for a silver shilling.
A Florin, also an old coin, 1950. I might be the first person to detect this area, or the first person with a detector good enough to see through all the black sand to get these deeper coins, someone had obviously gone through and cleaned up any modern shallow finds as I wasn't finding modern coins.
I was finding Target ID's were terrible until I had them out of the dig holes, the black sand really messed with ID's so I was just digging all targets, often hunting in pinpoint mode as it worked better than normal modes, especially now I knew there was old deep coins.
This one was quite deep too, I found it in pinpoint mode, I had no idea what I'd found at the time, a coin I'd never seen before.
It's from French Polynesia.
A nice bit of Paua Shell (Abalone)
Nothing down near the water, most the coins I found were in that sluiced out looking channel that I guess the tides washed out.
Time to go pick my daughter up.... The time went way too fast as I was having fun.
All except the bright silver coin are old currency, no longer in circulation. The only junk I found the entire time were the two sinkers.
And the French Polynesia coin.
It's 100 French Franc's from 1984 with a mintage of about 500,000 and some info about it here https://en.numista.com/catalogue/pieces1356.html
French Polynesia is a French overseas collectivity in the South Pacific between Australia and Chile. Its main island is Tahiti and its population is 270,000.
Might of been a good place to use the Fisher Impulse AQ.... no junk, plenty of finds, lots of black sand...... Only problem is I don't have one, yet..... I might try the QED there next time. This time I wasn't even armed with a sand scoop or anything, just my prospecting plastic scoop, I was very under prepared for a beach detect, at least I had the F-pulse with me as it handles the beach well, much better than my Carrot AT.

I have been wanting to do a little video like this for quite awhile but videos are definitely not my thing. Anyway, I have a contact in the storage unit auction business that lets me know when they win auctions with prospecting equipment. They recently won a unit that they are still going through that had two brand new Minelab Vanquish 540s, a basically new Tesoro Cibola and a brand new Garrett AT Pro. I bought three of them to do some testing and sell later or keep if I liked them. I sold the 540 already since I know what it can do.
This short 4 minute attempt at a video is for target ID accuracy and up averaging of IDs in mineralized dirt. This test video is of four 14kHz or higher mid level detectors on a surface US nickel, 4" nickel and 6" nickel under the gray cap, which has been buried for several years. Also there is a surface US quarter and a 6" quarter under the red cap. The detectors in order are the XP Deus, Tesoro Cibola, Garrett AT Pro and the Minelab Equinox 800.
The XP Deus is ground balanced at 87 and uses stock Coin Fast at 17.5 kHz with the 9" X35 coil, 90 sensitivity. Please pay close attention to the small vertical mineralization bar on the far right side of the display which stays half to over 2/3s full. The Cibola with the 9X8 elliptical concentric, sensitivity on 8, is set up to just notch out US nickels and hit everything higher. The headphone volume is not very loud, sorry. Notice how the Cibola deeper nickel targets are no longer notched out.......if you can hear the audio and how the Cibola can barely hit the 6" quarter which has been buried for several years. The Garrett AT Pro, 8.5"X11" DD coil is in Pro Zero with discrimination set at 35, no other notching, sensitivity on the next highest setting and ground balanced at 93. The Minelab Equinox 800 is in Park 2. It ground balanced at 2 and the EMI is so bad that sensitivity is set at 14 of 25. I left it in my custom 5 tone very harmonious setting and also did a noise cancel. Otherwise no other adjustments were made. To further handicap the Nox 800 besides using 5 tones (50 tones are more accurate) and sensitivity on 14, I also put the 6" DD coil on the 800. Watch all the way to the end if you can when I do a slightly different test with the NOX!
Again, 3 US nickel targets and 2 US quarters with the deepest targets at 6".
Thanks for watching and my apologies for this poor attempt at a test video. Turn you volume up and because I am dumb, rewind to the very beginning since it starts about 20 seconds in if you don't. My bad.
Volume Limit on the Z, from the Manual..............
The Volume Limit sets the maximum volume for target signals. When detecting, the sound produced by a target can be very loud. Adjust the Volume Limit to ensure that loud targets do not hurt your ears. The Volume Limit has a range of 1-20, with a preset of 12.
And of course a lower Volume Limit will reduce the difference between small and big targets.
When using the WM12 and headphones I have the volume limit at 7, reason being I have Tinnitus and do not want sudden loud sound to make it worse. Am wondering does this low setting have an impact on any other function of the Z. I can still find very very small pieces of wire/gold.
I was sent this video, the x-coil runs very nicely in the wet ground, just remember these coils are not water proof so don't submerge them.
I'm not sure if the nugget was stuck down deep or kept sliding back into the hole from the water, but anyway what impressed me was how well the 10" x-coil was handling the wet ground.
Anyway I just though I would share the guys video with you all.

Hello I live in Las Vegas anybody have suggestions where I can go. I have a equinox 800 and I believe I have problems with it. Have not found any gold and getting frustrated with very little help from Minelab. Need ground I can test it out on tkk on se if there is a problem with it.
any help would be appreciated
