Technical Detecting Forums

Recommended Posts

I was interested in exchanging info such as the noise voltage density per m^2 of out here in my location, nV/√Hz/m^2 but didn't see a appropriate category on the forum. I was wondering if anyone knows of a metal detecting forum where there might be people who design metal detectors.

These forums revolve around the use of metal detectors. The only tech forum of consequence that I know of is the Geotech website and forum. Owned and operated by Carl Moreland. He was with White’s Electronics and now is at First Texas (Bounty Hunter, Fisher, and Teknetics). Also coauthored this book:

Inside the Metal Detector explains theory and offers numerous experiments and projects that demonstrate the theory. You can build an off-resonance pinpointer, a GEB-discriminator, and a microprocessor-controlled PI detector. Even if you're not inclined to build a detector, the concepts learned from ITMD will help you better understand how your own detector works and what all those controls are really doing. The book can be purchased as paperback or Kindle format on Amazon

I'll check out Geotech forum. Another possibility is a forum that doesn't necessarily have much tech talk but perhaps a few detector designers who hang out there. Thanks

Many engineers and designers do not actually metal detect, so their reasons for being on a forum differ from the regular users. They hang out on many forums but rarely participate. Many watch this forum for instance, especially from Minelab. Carl and Dave Johnson from First Texas used to post on many forums, but are rarely seen these days.

Tom Dankowski is not a detector engineer per se but is a techie type and runs his own forum here. Carl pops up there occasionally.

I can relate lol! Perhaps my story is a different case, but I used to love to play video games until I started working for a gaming company writing game source code. I guess designing & coding video games all day can do that sometimes. Hopefully that's not the case for metal detecting. I enjoy working designing & building the metal detector, but so far I can hardly wait to hit the road headed for nature. No doubt nugget hunting is hard work but I can hardly wait. ?

      Dealers are welcome on these forums. I do as a rule prefer dealers identify themselves when posting. Putting dealership contact information is the signature line is encouraged for this reason, and can bring the dealer some business! 
      Unlike most forums this one is not owned or sponsored by detector dealers. However, I respect many dealers as being some of the most knowledgeable people in metal detecting. To ban them here would be a bad idea. I in fact would like to attract them. I welcome any posts from any dealer intended to enlighten and inform. Any smart dealer should know people do not like overt sales. The way to go about it is show you know your stuff. Help people. Be useful.

      I also do not mind dealers advertising in the Classifieds and in fact again, I welcome it. There are limits however. First, you must identify yourself as a dealer in your ad. Second, only advertise real deals. Genuine limited time offers that people would regret not knowing about. Do not "flood" the Classifieds with ads. A few good quality listings is better than sheer volume. As a rule a dealer should have no more than two ads in the Classifieds at any one time; if more are posted I may delete the oldest ones at my option. And do note that no ads stay up forever unless updated regularly. After 90 days any ad may be deleted. Again, at my option and I am not looking to be draconian but am pretty forgiving. I try to see what the intent is and work with that.

      In particular, dealer ad listings for used detectors and demo units are most welcome. Offer the members of the forum real deals, and you will be appreciated.
      Dealers can be aggressive types but if so they will meet their match in me. I have very high standards for this forum and demand polite, informative discourse. Anyone wanting anything else, well, the internet is loaded with places that cater to everything else. Here, we stick to meat and potatoes. Advice from my 35 years in retail - talk about what you do that is good, not about what other dealer do or do not do. People do not like it when dealers talk others down.

      This site will always put regular member interest first over dealer interests. Any member who has a problem with or objects to the behavior of any dealer on the forum, please PM me with your concerns. One person complaining that a dealer did them wrong may not sway me but on the other hand I do not want to support dealers in any way that do not make a habit of going above and beyond for their customers. Since this is all an experiment I am making up as I go you can bet I will be watching like a hawk and make adjustments in practices and policy going forward as I see fit.

      I and probably many of you have been experiencing forum connection issues recently. Some of it was a database server crash, and part of it a corrupted file due to the crash.
      However, the forum database is also getting large, over 2GB now. I May do a prune of all members who have not logged in or posted in over a year. This has not been done in years so there are thousands of inactive accounts taking up space. If you have not logged in or posted in over a year now is the time, otherwise your account may disappear. You can see the forum without an account though you can’t download files and such. Bottom line is if you are not logging in or posting you don’t need an account so I will be cleaning that up very soon. I figure a year is long enough to be reasonable but if anyone thinks that’s too little please speak up!
      I am also going to delete the photo gallery. It gets very little use but is a resource hog. 90% of the photos there are mine, and I may move them to my personal website then link there. Almost no members are using the Gallery and it is a separate module I pay for on top of the other forum costs. I suspect most members don’t even know it exists. So that’s going away unless you all rise up in protest! 
      Simultaneous members online at once has been climbing rather rapidly. 133 on the site as I type, and that alone may be causing connection refusals due to the forum being on a shared database server. So concurrent with the above I am working with my hosting service to move from a shared database server to my own VPS dedicated database server. This will help protect the forum performance from being impacted perhaps by other server users (and them by us), and allow me to isolate and more easily diagnose any issues here.
      Add all this up and we should all see better forum access and speed very soon. To anyone experiencing these issues, my apologies. The good news is that this is all because the forum is growing while most seem to be shrinking, so in a weird way I’m happy to be bumping into server limits. Just wanted to let you all know I do pay attention to this stuff and try to do what is needed to keep things humming along smoothly.

      I just want to interject here and say, that I’ve been to a lot of forums on the net, but “Detector Prospector” is the best on the internet. A good place for non-biased information. Quick responses, non argumentative, a great group of contributors. I am glad that I joined. Hopefully we will all be here for the next several decades.

      Hey Steve,
      I was wondering if there would be a way for everyone to have access to a page or folder or whatever that we could simply call "pictures"--- it would be an ongoing thread per se that everyone could add to...
      The folder should be easy to upload pictures with a short description..... that way we dont have to make a new thread every time we just want to show what we found detecting that day---
      In my mind it would be like a calendar with all the days finds on it..... the next day would start over with the new finds for that day...
      ???????????
      Maybe you could modify this idea into something usable.....
      Thx Steve.....and BTW I went to Round Hill at Tahoe this evening and got about 19 cents!!!!!
      A dime sounded really good on the Makro Gold Racer with the 15.5 inch by 13.5 inch coil at about 8"s
      NEVER MIND---I TRIPPED OVER THE GALLERY FOLDER RIGHT WHEN I WAS LEAVING THIS PAGE!!!!!
      DOES THE IMAGE FOLDER NOTIFY EVERYONE WHEN A NEW SET OF IMAGES ARE UPLOAded???

      Just some stats for those who may wonder about such things. In the last year (July 2018 - July 2019) this website had just over 350,000 unique visitors (each person counted once, not every time they post). The top ten countries....
      United States 55.5% Australia 13.93% United Kingdom 8.22% Canada 2.45% France 1.19% Germany 1.18% Italy 1.06% Netherlands 0.99% Turkey 0.92% Russia 0.71%
