An underwater observation system has an underwater camera attached to a viewing system. The viewing system has a CRT display disposed within a case. A magnifying antiglare lens is positioned in the case a desired distance from the CRT display to provide a view of images displayed on the CRT. A cable couples the camera to the viewing system. A movable screen is attached to the viewing system to further reduce glare. One or more LEDs are housed in or on a body of the underwater camera. The LEDs may emit red or white light, or a combination of both to provide enhanced visibility of desired objects. The camera body has a removable fin for stabilizing the camera as it moves through water. The cable has marks spaced along the cable to indicate distance from the body of the camera. Alternatively, the camera is provided with a depth measuring sensor. Further sensors include a compass for indicating orientation of the underwater camera and a temperature sensor. A telescoping pole may also be attached to the camera to provide better control of depth and orientation of the camera.
