Liquid Image have been making photo and video equipped dive masks for a while now, but things have turned serious with the Liquid Image Scuba Series HD dive mask. It has a 5.0MP digital camera and a 720p HD video camera that shoots at 30 fps. You can scuba dive to 35m with the mask or just use it for snorkeling or freediving. It needs 4 AAA batteries which should last for 2,000 images or 2 hours of video if you use lithium ones, and takes microSDHC cards (up to 32Gb). Comes in two sizes and you can add video lights and coloured filters to help you get the best results. Pick one up from Amazon for US$249.
Keep your hands free as you dive! This is the world’s only dive mask that has an integrated water resistant High Definition 720P digital video camera plus 5.0MP photographs. Operates to a depth of 115ft / 35m and eliminates the need to hand carry an underwater camera. Ideal for scuba diving and may also be used for snorkeling, scuba, spearfishing, and freediving.
