The Hook-Eye Sportfishing Cam is designed to be attached to any fishing line or leader in order to capture fast action and shoot high-definition videos even in extreme conditions, such as Marlin fight. Its unique hydro-dynamic design and features make it the ultimate action camera for all kinds of underwater activities, with a particular attention to Big Game and sportfishing, which is what it was born for. Hook-Eye features a fishing line attachment system placed along the bottom of the body, which allows sliding the camera through the leader into the water, with no need to cut the line. The camera is then free to slide back and forth on the line, following action without ever interfering with it.
