Video Swim Mask

This is the world's only swim mask with an integrated waterproof digital camera that works swimmingly in pools, lakes, or the ocean. Shoot all of the magic that happens underwater and keep your hands free as you swim. No need to carry an underwater camera to record pictures or video.
With a LED inside the mask to let you know which mode you've selected, the Video Swim Mask makes it is easy to choose between photo and video. It comes with a built-in 16 MB memory for instant use and a micro SD slot to expand the memory up to 2GB. You can download images easily by plugging the mask into your computer via USB cable that is included.
