Abstract: An electronic cycle control for electric downriggers providing the fisherman with a selection of amplitude for up and down motion at fishing depth for the ball or weight and offering a selection of dwell at each extreme of movement and functioning automatically and repetitively until terminated by the fisherman. The electronic control unit operates as a piggyback operator on the reversing relays of the electric motor of the downrigger.

Abstract: An improved temperature and depth indicating downrigger reel in which the reel drum provides a nest between the spokes for thermal electronic indicator apparatus and in which the cable forms the conductor element to a thermal sensor element adjacent the end thereof. A calibrated gage supported in a two-piece housing provides electrometric read-out from between the spokes of the cable carrying drum and one end of the cable is attached to the gage. Power for operation of the thermometric read-out gage is contained in the drum in the two-piece case and at or adjacent the gage. A friction wedge lock is provided which acts between the flanges of the drum to selectively limit pay out of cable. Simultaneous depth read-out is provided by a counter indicator showing the amount of cable payed out and being an indicator of depth. Continuous read-out of temperatures is provided.
