Want to keep your hands free while snorkeling? Hell, you can do that too! This mask has a built-in HD camcorder (it also takes 5-megapixel photos) that’s safe to use at depths of up to 130 feet. With crosshairs on the lens that make aiming the camera as simple as looking at something, it’s the perfect aquatic companion (unless you have a talking eel friend called Brian that rides a magical conch shell and knows how to get to the secret dolphin-only undersea fairground. Because we dreamed about that once, and frankly, it kicked this camera’s ass).
