Prospecting & Detecting
Selectable Frequency vs Multi Frequency Detectors
March 2017 by Steve Herschbach
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
A Great Day On The Feather River
Mike and Machael dug in just downriver of that boulder pile and right away found good color and a few small pickers.
Prospecting for Gold in Baja California
It was one of those awkward situations as we walked, fatigued and too thirsty to speak a word.

Detecting Alluvial Bench Deposits -- Pt II
Walking around the gulch and exploring the upper drainage, picking up different rocks and inspecting them with a good loop, and looking them up in a field guide of rocks and minerals of your region will help you understand how the gold got there.
Volume is the Key to Success
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
