Pros and Cons of Big Detector Coils
December 2016 by Chris RalphYears later I returned with a new detector with a smaller coil and detector technology more sensitive to smaller nuggets. I found my first nugget within five minutes. I had a second five minutes after that.
The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
When we got set up and I started to swing the coil over a small mound, I got a good signal, faint but repeatable.
Detectors were invented long before I was born, but it was in the 1960s when they started to become an item popular enough to power a fledgling industry. The key development was miniature transistor technology replacing the old fashioned tube technology of the 1950s, making lightweight, affordable detectors possible.
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
A retired gold prospector spent hours digging up his fortune in the northern goldfields near Kambalda, Western Australia, after finding the target with his metal detector.
Patience and persistence is the name of the game when you are detecting this way for gold, as you will have to do a lot of work preparing the ground to detect with any degree of success.
