Abstract: Fishing assistance devices adapted to create a jigging action in a lure as a fishing line is reeled in, and fishing systems and methods utilizing such a fishing assistance device. Such a fishing assistance device includes a coupler configured to removably attach to a rod blank of a fishing rod at a location between a spinning reel and a first guide on the rod blank, and a guide arm supported by the coupler. The guide arm is configured to alter a path of the fishing line between the first guide and a bail of the spinning reel as the bail rotates around a spool of the spinning reel and winds the fishing line around the spool.

Abstract: A transmission apparatus includes a chain operatively engaged with a driver sprocket assembly and a driven sprocket assembly, a tensioner bracket including a roller engaged with the chain, a tensioner rod including a plurality of spaced apart flange portions engageable with a brace and a threaded portion extending through an opening formed in the tensioner bracket and screwably attached to a plate. An operator may unscrew the tensioner rod and pass at least one of the flange portions through a slot in the brace to slacken the chain. The operator may also position at least one flange portion in a narrow end of the slot, and screw the tensioner rod to press that flange against the brace to tighten the chain.
