Better than a removable eyeball.
With its long, thin probe, the PalmScope delves into tight inaccessible places and reveals their secrets on a crisp 2.7-inch LCD display. Smartphone-size construction makes it a cinch to use while your other hand wields a tool – and if you get clumsy, it’s certified “drop-proof” up to one meter. The waterproof probe includes attachments like a pickup hook, magnetic pickup, and mirror for nifty extra functionality. Runs on four AAA batteries.
