It is easy for many hobbyists around here to get caught up in all the newness that manufactures keep offering. For those who hunt a wide-range of targets in widely-varying sizes and shapes and alloys, it is tough to beat a good analog detector.
Most metal detectors got their start here in the USA, and without a doubt the bulk of the quality built products come from manufacturers here. Yes, there are some well designed models from what we consider to be foreign sources, but most hobbyists are here in the USA and get their detectors her, and for what most hobbyists tend to enjoy. That enjoyment comes from Coin Hunting.
Yes, you can hunt coins in other lands, but separate metal detecting hobbyists into one of two groups:
A "Traditional Coin Hunter" or an "Avid Detectorist."
Metal detector design used to be quite simple, You chose either BFO or a TR model and hunted. Found something and you heard a motorboat increase in beats (BFO) or a 'Beep' (TR), then you recovered it, looked at it, and decided if you wanted it or not.
Then came variable Discrimination and we could reject some of the lower-conductive targets and be a little more selective in what might give us a 'Beep.'
In only a few short years, by '75, we had the VLF (very low frequency) models that gave us ground cancellation from most major manufacturers and we could balance out the ground signal, search, get a 'Beep,' recover it, and take a look to see what we found. Any type of soil in any country, we all had the same options. Then came the dual mode VLF/TR-Disc. models in the '70s, then in 1978 our first motion-based VLF Discriminator (the Bounty Hunter Red Baron), and in no time at all, every major detector maker had copied or designed their own. Most were a fast-sweep 4-filter design, but we could still follow the same steps. All of us might reject some lower-conductivity targets, then search, get a 'Beep,' recover the target and determine if it was a keeper or not.
In '82/'83 we got our first slow-motion, 2-filter type detectors, and very shortly in
