The Camera That Started a Movement Born from a passion to capture your adventures from your perspective, the completely redesigned HERO3: Editions line of cameras are the most advanced GoPro cameras, ever. Versatility Unprecedented Durability Shockproof and waterproof to 197' (60m), and proven in heavy surf from Tahiti to Northern California and everywhere in between, GoPro cameras can handle it thanks their highly engineered poly carbonate exoskeleton housing. Ready for action—from scuba diving to dirt track racing, and tough enough to take a spin across the asphalt or launch into space, GoPros are built to take a beating and keep filming. Replacement lens kits and housings are available, so there’s little worry while going for glory—even while diving with sharks. Wear it. Mount it. Love it.™
