An improved troller for use with a fishing line that is capable of being varied in weight and of releasing when the troller contacts the tip of a fishing rod. The troller has a hollow casing and a ball movably disposed therein, one portion of the casing interior being tapered for wedging and locking the line between the casing and the ball in response to the pull of the line, a second portion of the casing interior being enlarged for movably encasing the ball after the troller has been released from the line in response to its contact with the tip of the fishing rod, and a third portion of the casing interior having at least one weight removably mounted therein.
