I hesitated with the purchase of this NPC-CAM S70 and GOPRO Hero 3 Black Edition, for I am a diver and I'm using that for this! So I make my choice on the S70 CAM NPC and I really regret not quality is the appointment waterproof case against 100 m 40m etc ... I will not make a novel but for half the price of the GoPro and has nothing to envy. I hope that this review will help you in your choice!
