Divide and Conquer—Detecting Old Placer Grounds with Friends
February 2014 by Ray MillsHe no sooner had turned around and started moving when I hollered again that I had another nice one.
Lately I’ve been having success utilizing two types of detectors in succession. The first is a pulse induction (PI) detector with a blanket-style antennae, and I follow it up with a very low frequency (VLF) detector.
“I heard him hollering down in the hole as soon as I got there,” he said. “I was just glad to see him alive.”
I detect in a wide array of situations. I like to search for places that no one has been to. I really like to find areas that have never been worked at all.
Years 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.
… I recently had the opportunity to sit down with Brent Weaver, Garrett’s chief design engineer to talk about gold-oriented detectors, how they work and how prospectors can get the most out of them.
At the end of the day, Jerry showed me how to clean out the sluice box and then how to pan out the concentrates. As we finished panning, there it was—a little tiny smile of gold...
There may be lots of smaller gold I cannot hear with a detector, but it looks just fine in my pan once it is out of the crevice.
