I started using detector back in the late sixties. The first one was a tube type detector and man were those detectors heavy with the large batteries needed for the tubes. I was in the Air Force and was a satellite electronics technician. I server in Vietnam during the Tet Offensive and was stationed in Saigon. My interest in metal detector was increased during that time and I played around with one or two thinking I would use them for coin hunting. The electronics and metal detecting hobby went well together and the old TR and BFO were fairly simply and easy to understand. You could get about 4 inches and at times a little more but that was about it on a dime. Many of us still managed to find thousands of coins and rings with those older detectors. You guys would have loved it back then when the parks were loaded. We would take a cigar box with us and when our pockets were full of coin and rings would empty them into the cigar box.
The first VLF detector was invented by George Payne and interesting enough would detect as deep on a dime as the ones we have today. It was too hot as you hit those dreaded nails at 10 to 12 inches and they sounded like they were right on top of the ground. Almost every feature you see on today detector other than multiple frequency are efforts to improve or correct the same problems of the first VLF detector.
I was fortunate in that as a satellite electronics technicain and having been trained as a radar tech I was afforded the opportunities to attend some of the best military and industrial electronic schools. My life during those days became one school after the other and I enrolled in any university that was close to were I was stationed. I completed a Bachelor of Science and Master of Science and most of my doctor's degree in industrial electronics and was a field engineer in Tulsa after retirement from the Air Force. I was offered a teaching position at Northeastern State University to build an electronic technology program. I accepted and that kept me busy for seventeen years. Those were the years when more theory was required but I had all the time needed to study and teach so pretty much went through the entire electronic filed for industrial electronics. It worked out well as it combined the practical expereinces from the military and industry with the need and time to really dig into the theory.
I retired in 2000 and at time was the network manager for the university. That gave me the opportunity to get into fiber optics and networking plus distance education and telecommuncations. This final retirement was the time to enjoy the hobby that had fascinated me for so many years as never before and pull the electronis career and hobby together for some good hunting.
As a retired professor and also retired from the military I could use any detector or as many as I cared to. I selected the following detectors and devoted my time to testing and using them. I seriously tested for depth, discrimination, and overall effective operation and stability. This was combined with extensive use in the field to see how the test compared to actual field use.

These are the ones tested in the last three years since retirement. There are too many to list for the prior years from 1969 to 2000 but included just about all the major manufacture and some that were hear one day and gone the next.
So, when you see my posts you know something about what I am doing and why. I see this like a TV station in that if you like it watch it and if not then don't. I do not have any interest in the back and forth arguements that accomplish nothing and will not waste my time or the participants of these outstanding forums with those kind of posts.
There are good solid reason, scientific, why you can only detect a dime so deep, why we detect a rusty nail and it is presented to us as a silver coin and the difference in tones. I am the type that thinks if I understand this then I can use that to my advantage. As a retired professor I also enjoy sharing with others what and why a detector does what it does.
Hope this helps to understand a little better my posts and why I post to several forums that are directed at detectors I use or have used.
Have a good one,
Cody
