The line depressor herein is for submerging trolling lines until a predetermined increased tension on the line shifts the point of pull in such a way that the depressor assumes an attitude in registry with the line of pull and thereby reduces resistance to the pulling of the line out of the water. Conversely, when the line depressor is in the water and is being held substantially in registry with the rod line and the hook line, it is only necessary to allow the rod line to go slack to cause the body to assume its trolling attitude and depress the line. The line depressor includes a body having at least one hydrodynamically depressing surface, and having a weighted rod end and a hook end; a curved guide is extended from the front rod end of said body upwardly and rearwardly with respect thereto; a resiliently expandable line is connected at one end thereof to the rod line and at its other end it is slidable on the curved guide between front and rear positions; an initially slack trip-line is connected at one end to the rod line and at its other end to said body in such a manner that when a predetermined force is exerted on the rod line, the expandable line pulls the trip line taut; the trip line pulls up the front end of the body causing the slidable end of the expandable line to slide to its front position on the guide and thereby simultaneously pulling the body into aligned position.
