And this is young me in 1978. Don't quite look like that now.
Treasure Hunting with metal detectors has been a hobby borne out of my interest and general knowledge of electronics.
Some 40 years ago, when I was building every conceivable electronic project published in trade magazines,
I also built my first metal detector, a basic BFO (Beat Frequency Oscillator) unit which over the following years
was further improved and then replaced with my own designed version of a more advanced type, an Induction Balanced (Transmit & Receive)
detector that was capable of finding coin size metallic objects down to 8/9 inches in the ground. Metal detecting,
then in its infancy, arose some serious interest among a group of local enthusiasts who found my designs simple
and affordable gadgets to find treasure with, and quite reliable they proved to be too, except for the hardware which was made from cheap recycled materials. Unfortunately, of the two or so dozens units built, all were sold and now regret not to have kept at least one for my collection.
After my first two years of building designs and prototypes, the industry moved on really quickly and I found that
for all my enthusiasm and energy, I only had limited resources that would not get me very far so it was then that
I decided to acquire a small lock-up shop and become an agent for the UK main importers, Joan Allen Electronics
and Regton Ltd as well as dealing directly with SAVO Electronics of Inverness that later changed to WHITES METAL
DETECTORS (USA), all of which are still operative today.
The first few commercial models arriving in the UK were mainly of American origin and many of the early basic detectors
from the likes of Fisher, Garrett and Whites soon gave way to some more sophisticated units which rapidly transformed
the hobby for the better.
It is true to say that, today, in spite of the gigantic steps forward in electronic technology, contemporary metal detectors,
almost unrecognizable in size, lightness and built quality to their 80s peers, are still essentially a two way transmit
and receive system, that needs to be hand held and swung about to obtain an audio signal output and or other visual display indication that requires proper understanding and interpretation by their operators.
There are more than 300 different types of metal detectors from many different brands in every price range, many claiming
to be the best performers with all their "must have" built in features, accessories, etc. making the choice even more daunting for the beginners or first time buyers.
