GoPro cameras form an integral part of most of my projects so I'll be following this new 2' monitoring solution closely. Everybody uses their smartphones to line up and control GoPros, but to be honest it's a pain in rear at times, especially when you're pressed for time and you can't get your phone to connect to the camera.
REMOVU connects via wifi and will give you an effective operating range of between 20 to 70 meters between you and the camera. At around R1500 it is perhaps a bit pricey, but if it works as advertised it could be destined to become a must-have item for serious GoPro'ers.
