Metal-Detecting Sandals
Details: Ever wonder what lies just below the surface at the beach? Tin cans, discarded razor wire, or—better yet—buried pirate treasure? Hammacher Schlemmer’s smart sandals use “beat frequency oscillation technology” to signal when a metallic object is underfoot. The downside: they detect a mere two feet underground—and you have to strap the battery pack to your calf (good luck explaining that tan line at the hotel pool).
Info: Hammacher.com; $59.95.
