I'll tell you this, Dave is a freaking Jewelry magnet... Pure and simple..
Whenever I hunt with him, he always seems to just pick that right line.. Case in point... We were hunting one spot, then decided to go WAY down the beach to another area.. So he starts going down the wet sand swinging like there is no tomorrow.. Fast pace, and surely missing a lot of ground.. I chose to stay near the water.. I'm watching him, and he suddenly makes a sharp turn to the left and starts swinging near the beach cut right at the edge of the dry sand.. He doesnt go 10 ft and suddenly stops... Starts digging and up comes a silver ring... %)((^)(%(**#*(# I utter to myself... So then I hit the high line and he drops down to the wet sand... Bam.. sooner than later he hits another signal... I cant remember what it was, but I remember saying to him "man, you just walk right to the good targets".... It's something to watch for sure, albeit sometimes discouraging...
Definitely an artist at this hunting thing...
