Long-handle stainless scoop
316 stainless · ~7mm holes · 40–50in handle · Mid · the one most beach hunters end up with
This is the default answer for beach detecting. A stainless basket on a 40–50 inch handle lets you drive the scoop in with your foot and lift without bending — which matters enormously when you're doing it two hundred times in an afternoon.
The long handle is the whole point in wet sand and the surf line. You stand upright, punch down, lift, and shake. With a hand scoop in the same conditions you're bent double with a wave arriving.
Look for 316 stainless rather than 304 — it's the marine grade and it's what survives saltwater without pitting. Brands worth searching: CKG, RTG, Stealth, T-Rex, and Nokta.
