During one of my prospection with my CTX3030, I noticed a competitor who was prospecting in an open pit gold field, collecting yellow mini nuggets and he had full pockets!
A bit later, another gold jewelry & diamonds lover was pinpointing his beak to recover my ring.
Fortunately, the animals do not have a Minelab, otherwise the competition would be fierce.
The day has not been good only for our animal friends, as a medieval coin "Billon" alloy of silver & bronze, made my CTX 3030 chirp).
