Take a SIEVE. Or an orange sack. Besides carrying your shells, it may help you catch them. A few pint BOTTLES will hold delicate ones.

MASK (or goggles) is essential for looking underwater. Bathing suit or old clothes, of course. High shoes (or sneakers)—never go barefooted! Heavy cloth GLOVES. Watch out for sunburn!

GIG or fish spear (if you're going South) to keep pesky crabs, sea urchins off. CLAM DIGGING HOE or trowel for burrowing shells.

VINEGAR for first aid, in case you're stuck by urchin's spines.

CHISEL and HAMMER to get the clingers, spatula for frail limpets.
You may find other hardware handy, but these are basic.
