Beachcombers, unpack that cumbersome metal-detecting equipment you take with you to look for buried treasure. Instead, Treasure Seekers’ Metal Detecting Sandals fit in your beach bag or suitcase and are a cinch to use. Strap the small battery pack, powered by a 9-volt battery, to your right leg and attach its cord to the sandal via a USB plug. Then head out for a stroll. A copper coil built into the sandal helps locate metal that’s up to 2 feet underground. These comfy rubber sandals, which have polyurethane foam footbeds and non-skid soles, come in two sizes: medium (men’s 7-9, women’s 8-10) and large (men’s 9-12, women’s 10-13). They sell for $59.99 at www.hammacher.com (800-321-1484).
