Abstract: An underwater surveillance apparatus includes a watertight housing having a transparent part and a video tube received in the watertight housing. The video tube has a light receiving end positioned to view through the transparent part of the watertight housing. A video cable extends from the video tube to a video monitor disposed above a surface of the body of water. The watertight housing is configured such that the transparent part of the watertight housing is urged in a direction downstream when the watertight housing is submerged in a body of fluid moving relative to the watertight housing.

Abstract: A submersible camera is releasably attached to a fishing line so that the submersible camera can observe the bait receiving end of the fishing line when the submersible camera and the bait receiving end of the fishing line are submerged in a body of water. The submersible camera is connected to a video monitor via video cable. By observing the bait receiving end of the fishing line on the video monitor a fisherman can obtain real time information regarding the fishing environment enabling the fisherman to make better informed decisions regarding the presence and desirability of fish, the attractiveness of the bait or lure to the fish, whether the fish are striking the bait, the appropriate time to apply a hooking yank, whether the fish is hooked and how aggressively should the fish be reeled in. This enables the fisherman to catch more desirable fish.
