The GoPro HERO3 Underwater HDMI Video Out Housing from Eye of Mine is designed specifically for the GoPro HERO3 and HERO3+ cameras. It uses the FLAT LENS 3D housing that provides room for the HDMI cable to enter from the left, while the camera fits into the right side of the housing. Both the camera's top and front buttons work when it's placed in the housing, however, the LCD screen will not work. The camera functions as it normally would without the HDMI cable.

The housing also accommodates the camera when a GoPro Battery BacPac (available separately), which doubles the battery life, is attached to it. The housing is pressure tested to a depth of up to 40' and comes with a 25' HDMI cable. The separately available HDMI signal booster may be required as some portable HDMI monitors don't accept weak HDMI signals and will either show no signal or a signal that will cut in and out. An optional, permanently installed USB power cable (not included) allows powering the camera down to a depth of 32'.
