Abstract
A trolling reel for raising and lowering a weighted control line to which a fishing line is detachably secured includes an electrically operated drive motor coupled to the reel for positioning the control line at a desired depth and securely holding the line when the motor is not actuated. The trolling apparatus is directly or remotely controlled and includes means indicating the length of control line extended. In one embodiment, control means are provided for fully raising the line by momentarily actuating a switch. In another embodiment, the control line is fabricated from a two-conducter electrical cable with a thermistor coupled to an end of the line which is extended at an angle from the lowered line by a spool to position the thermistor in proximity to the fishing lure. A remote temperature reading instrument is coupled to the control line through a slip ring assembly positioned on the reel and reel frame.
