Abstract
A modular, submersible video viewing system. The system includes a viewing monitor, camera and interconnecting multi-conductor cable that store at a portable housing and deploy for underwater viewing. Webs at the camera housing interconnect to cable clips, bottom support plates, a swivel coupler or steering guide and/or pole to control camera orientation when towed or during stationary or pole directed viewing. Alternative rudders and/or hydrodynamic ballast weights (with or without a keel) mount to the webs to control camera tracking. A multi-aperture reflection suppressor and etched lens mount to the camera and cooperate with a series of LED's to direct light relative to the viewing field of the camera lens. Various sunshields, lights and/or lenses and filters are optionally mountable to the monitor housing or camera. Alternative monitor housings are disclosed that contain the viewing monitor, battery and attendant control circuitry and camera. Handles, cable wraps, cable take-up spools and integral and detachable sunshields are also disclosed. A video storage/re-play feature and combinations of switched multi-frequency lights are also included.
