10" GPZ 🫡

Now in Paeroa! The trip is coming to a close. I'm back with relatives and will have dinner in Auckland on Saturday. Other than landing at the airport, I haven't been there. Everything has been country and mountain roads. I've passed through lots of places I don't know anything about so I'll look at my pictures and a bit of Wikipedia later and then know more about what happened there. We've hit a couple of really nice playgrounds for the kids. The one today was in Hamilton. When leaving we had a great choice of takeaways to choose from. Pretty good stuff really. The exchange rate makes the food here about the same that I'd pay in California (when I left) but I've read about the bump ups in both food and gas. Most gas here is between $2.75-$2.91 NZ per liter for 91. I'm using a Toyota that gets better mileage than my cars in California. We went one stretch where there was no gas for over 100 miles. I was glad to pay $3.14 when I got to that station! Lots of things seen and many things to consider. If I ever made another trip to NZ I won't have to drive everywhere, that is for sure.

Wow....rough conditions indeed but the pay off was there. You had to work for it! I can only imagine 110 rings for the year in my dreams. Great hunting skills, great locations you have. Thanks for posting.

Morning/Evening wherever you are.I m looking for 1 or more 4" 5 pins concentric Tesoro coils they are now rare as hens teeth in the UK,France no luck I dont need the 5" from NEL or whatever i m just looking for a 4" white CC If you know someone who as one in a closet please let me know . Thanks RR

Yes, a database glitch caused Steve to have to reset reactions, nothing wrong on your end.

Hi all. Just want to put it out there, I've just made my first youtube video. I'll aim for somewhat regular uploads as I have hours of footage saved up. This is a video where I found 5 gold rings, a silver bar, a watch and some gold pendants. Probably in my top 10 favourite hunts. You don't have to subscribe, but it would definitely help 🙂 I'm fully open to criticism no matter how harsh. if you think the video is crap let me know what I can change. if you want it shorter or longer, or more talking? This took me forever to edit as I'm fairly new to it all. Otherwise I hope you enjoy the video. cheers.

I've been lazy with uploading lately. I'm either flat out with work or detecting and finding more than I can document! I've just hit 110 rings for the year (39 gold, yay)! Went out a few days ago with a mate and hit a spot we've been doing all year. After a few hours, he had a couple of rings and I had a couple of silver and a 18ct. I was pretty happy with that, but the tide started to come up and it was getting a bit cold and not much else was turning up. The beach has been good to us lately, I did the spot a few days prior just wading and scored 2 gold rings, and he went as well the next day and got another. We pondered doing another beach we both know well, where there's always tons of stuff but the conditions are extremely hard to do. Wow oh wow was it rough!! I said to him, I'll have a look and if its crap I'm gonna get a coffee and call it a day, I think he was a bit more keen than me. I took the long way around (got distracted by a garage sale lol) and we both met in the middle along the shore. Still equip with our snorkelling gear, we decided to go in anyway, as it was rough but the water was somewhat clear. For reference, I've found close to 600 rings scattered in this area over the last 5 years. They always get thrown up in to the shallow areas after rough seas, but we've never really gone in the water as the rips are so strong and the conditions never line up. Anyhow, within 24 minutes I had 2 bangles as well as 2 rings and he found 2 rings coming from the opposite direction. It was sooo hard to dig anything because as soon as you got the target, you'd be pushed off by a wave and would have to find it again. It was exhausting, especially with 11kg of dive weights. The rip was also extremely strong. I've never seen so many rocks in this spot, because again, it's near impossible to access. There were sooo many targets, almost 1 ever 1.5 meters. When I last got close to this spot I pulled over 70 rings but it was as they'd been thrown closer to shore by strong tides. Great day out. I went back 2 days later and while my partner was doing the shallows with her new manticore, I decided to wade in. my first target was a kayak anchor..lol, I wouldn't have dug it if it wasn't on the surface as it was a massive ferrous signal. This was equally as annoying as it was great, because I didn't have my dive weights so it gave me lots of weight to stay down, as my wetsuit is too buoyant. I was about chest deep the entire time (i'm 6t5) and it was a real struggle, the waves were hitting about 1.5-1.8 meters every 13 seconds. Again, soo many targets but after an hour I ended up with another 6 rings, 2 watches, a bangle and a brass bracelet chain. Including a nice 18ct band. As fun as it was, I think the 15 degree C water (59 fahren) was a bit too much and I'm now in bed with a cold, LOL. Totally worth it though. I'm so so so excited to go back there when we have a low swell, I just know there's going to be so much more there. I've never considered that all these rings washing up must be getting pushed from out in the deeper end. I was optimistic about the Seiko as I didn't see the water bubble at first.. it's a $600 watch. Sadly it's full of water. Here's a quick video just to show the conditions we were dealing with

Ah ha, Mn you came downunder to get an Algo.... love it. Keen to hear how you go with it, I hope you relocated Phrunts 12"X GPX coil into your bag.😉

Out of curiosity, is it just my device, or does it seem like the reactions to multiple post threads have been reset? I am certain I thanked or liked multiple responses to some threads, but those posts now show either no reactions, or only 1-2 very recent reactions.

ZVT is PI, not VLF. It has a high slew followed by a dead time, another high slew, another dead time, etc. You only get a reactive signal during the high slew and a reactive signal is required for discrimination. But all the sampling is done during the dead time. Yes, Garrett could resurrect it. I've heard through the rumor mill that Garrett looked at it but either didn't know what to do with it or wasn't interested. As @tboykin mentioned above, White's also didn't know what to do with it. I wrote a patent for it and the patent gives all the info needed to understand it, and I left a fully working prototype and all the firmware (in C, portable to any micro). The turnover was high at White's and with new engineers this would have been an advanced project. I have no idea what the engineering landscape looks like at Garrett, but I'm sure they could figure it out. Half sine is a true hybrid technology. You get a full VLF response at the same time you get a PI response. You can also run it multifrequency and multi-pulse at the same time. I think my prototype was single frequency but I also built a 3-frequency transmitter, just never hooked it up to a receiver. After my earlier post, I was off to the dentist for a root canal. While sitting in the chair I thought, waitasec, didn't someone market one of these? Thanks for the reminder. Not only that, but on the bench you can swing targets and get nice looking responses. But then you put the coil to the ground, and it's just a mess. I've seen engineers who thought they had designed a great detector, and when they get it in the field they just start crying. All that said, I think AI will slowly work its way into detectors, but don't expect a whole lot from it. And metal detectors tend to be late adopters of technology, so don't expect it soon. This topic of VLF+PI has come up before, and every time it does I get all worked up and wanting to jump back into those old designs. But then I remember I haven't finished writing that damned book, so I exercise some self-restraint and go back to writing. The book is almost done, and I will move these projects to the top of my to-do list. Should be fun.

Dean, you are an inspiration. Doing what you do with age pathology issues. I bet you would actually be in worse shape if your prospecting hobby ceased. I have been working with pt's with hip/knee replacements, #'d ankles, broken shoulders etc. The worst thing anyone can do later on in life is give up physical work. If we do, the body begins getting ris of calcium from our bones, making them much more brittle and prone to breaking with poor healing results. I say "go for it!" Dean. Anyone with a little common sense realizes the old saying....if you don't use it, you loose it. 👍

I've spent a lot of time hunting side by side with a guy both of us using our 6000's.. mine had the speaker up date/fix his did not.....now his does. Do your self a favor...if you have an older 6000 that needs the speaker fix... get it fixed...you trusted minelab enough to buy their machine in the first place why not trust them to fix it... strick

We tried to continue it for about a year after I took over engineering, but the documentation was a couple of notebooks, shoeboxes of parts, and not much else. We dug through boxes and boxes of what I assume was your stuff trying to figure everything out. The employee turnover at White’s was really bad, and the inmates were running the prison for too many years. It could have been a great product with the right combination of resources, guidance, and time. It was the one project I was really excited about, but the poor project management, lack of documentation, and overall disarray of engineering (and management) made it challenging to even figure out which PCB’s were supposed to talk to each other. Good lesson for future engineers and project managers- document everything so that the next guy can continue the work.

Every week we see prices cut on detectors that’s already made a name for them self in the field. Now here comes a new kid on the block with two PI detectors and want in on a slice of American pie better known as the market. With so many sales going on before will people who need to move first on what they have will they be able to? I don’t care who you are we all have a limit on a hit we’ll take to buy another. I do believe it will be people who never had a PI before if the price is low enough will have one now. It will be beach hunters and like Nokta said one is a relic PI detector. A lot of people are benefiting from all the sales we see every week but at the same time they saturating the market with their product and leaving little room are none at all for a new PI . Nokta all I can say the naming game is over and I hope to see your two PI detectors on the market soon. That saturation point is getting larger every day and with all the sales we haven’t seen nothing yet. The Best To You Nokta! Chuck

i blame the haircut o wait.................................................i m bald :") RR

Well you could've fooled me. You seem extremely knowledgeable of Detectors and how they work.

Ok, I've had correspondence with FT about the issues with their website, and the manuals, they've now given me the correct F19 manual PDF, without all the bizarre OCR or drunk PDF creator errors the one currently hosted on DP has like in the picture below So, here is the new manual with correct formatting. F19 Manual Download Link @Steve Herschbach may want to update the one stored locally here to the new fixed version too. They are now going through and checking and fixing all links on the website, including fixing up the incorrect battery information on models.

Yes John, my experience is that most of the gold drops into the first riffle or second one, that tells me the system is working. I'm reminded of a quote from a little 'gem' of an Australian made movie 'The Castle' 'tell him he's dreamin'. Translation: a response to an ad in The Trading post for someone that's asking too much money for jousting sticks, Erik Oostra, geof_junk and others may know what I'm talking about.

Its just a mono AI coil. The fold increases sensitivity but reduces depth by a big margin. Best benefit is noise canceling around powerlines or other high EMI environments. PMC here in Australia made a lot these too.

Testing is supposed to be about actual testing....to prove that the design is capable in all ground types and detecting styles....leave the promotion to others. Sad that so many offerings have succumbed to 'lollipop' social media and glossy video promos instead of silent, closed door professional testing. Minelab do both, but only after the testing has been completed. Algoforce don't need it either. I suppose we will hear soon re the name...gonna be interesting!

Yes, artificial intelligence can do a lot... but it depends on the area of use... if you zoom in on this picture, you will see how a modern denoising program can edit a noisy photo.. the results are excellent.. it's also because the AI knows exactly what to do... In detection, it is no longer so clear,,, and there are too many factors that affect detection

Yea, here too. I don't get it. The water is a nice 78 degrees and there are quite a few sunbathers, but nobody in the water. I'm thinking the air temp needs to get hotter and humidity needs to move in in order to make them want to cool off in the water. Maybe they are just waiting for the June/summer last school bell to ring before getting wet. I'll be out there. 😁

That's true Norvic, you were fine with the noise, others were not, they fixed the noise, now the detector is better for everyone 🙂

This is why Nvidia is suddenly one of the big guns! Went from making video cards to help us play some games to making video processing for AI purposes.

Now I only hope we are not messing with Gerry’s dream.😩 I remember Star Trek had a flip phone before anyone even imagined a cell phone, now look were we are at. 😃
