Find the coin line, then stop wandering
Waves sort targets by weight, shape, and density. When you hit several coins, sinkers, or similar-weight targets along the same elevation, you may have found the active line.
Field move
Mark that elevation mentally and grid parallel to the water instead of continuing random zig-zags.
Cuts matter most when they expose older sand
A storm cut is not automatically good. The productive version has a clear face, darker or compacted sand below it, shell hash, black sand, clay, gravel, or older target clues.
Field move
Work the base of the cut, the top edge, and the trough just seaward. If the face is all fluffy new sand, move on.
Black sand is a clue and a machine test
Black sand usually means heavier minerals have concentrated. That can point to the same sorting action that concentrates coins and jewelry, but it can also make detectors noisy.
Field move
Slow down, ground balance, and reduce sensitivity if needed. Do not leave just because the machine gets chatty.
A greenie means old copper survived there
Detectorists call a green-patina copper coin a greenie. It does not guarantee gold, but on a beach it can hint that older, heavier, long-buried targets are being exposed or preserved in that layer.
Field move
When you find one, slow down. Spiral out, then grid the same elevation before leaving the area.
One good target can have friends
Rings, coins, sinkers, and older copper often cluster because water sorted them into the same pocket. Beginners celebrate and walk away; better hunters interrogate the spot.
Field move
After any strong keeper, rescan the hole, then work a 10- to 20-foot radius before moving on.
Use crowd events like weather
A beach concert, tournament, race, or packed holiday can matter almost as much as tide. Fresh drops load towel lines, access paths, and gathering points.
Field move
Hunt early the next morning, starting at access funnels and setup zones before the beach fills again.
