Abstract: A fishing rod assembly includes a rod and a reel assembly. The reel assembly includes a housing, a spool positioned within the housing, the spool configured to rotate about an axis to retrieve or let out a fishing line, a drive mechanism concentric with the axis, the drive mechanism configured to receive rotational kinetic energy from a user and drive the spool to take-up fishing line when a counter-torque provided to the spool by the fishing line is less than a target torque, and a drag mechanism. The drag mechanism is configured to be driven by the drive mechanism and at least one of (a) drive the spool to take-up the fishing line when the counter-torque provided to the spool by the fishing line is less than the target torque or (b) provide a drag force to the spool when the counter-torque provided to the spool by the fishing line is less than the target torque.

Abstract: A fishing rod assembly includes a rod and a reel assembly. The reel assembly includes a housing, a spool positioned within the housing, the spool configured to rotate about a central axis to retrieve or let out fishing line, and a gear set configured to drive the spool to rotate about the central axis, the gear set includes a first set of gears and a second set of gears. The gear set is configured to receive input rotational kinetic energy through the second set of gears and output rotational kinetic energy to the spool through the first set of gears. The first set of gears includes a planetary gear set arranged about the central axis, and the second set of gears is arranged about an offset axis that is spaced from the central axis.

Abstract: A baitcaster includes a spool, a guide member, and a line guide mechanism. The spool is configured to be driven to take up a fishing line. The guide member is configured to transition between a first state for let out of the fishing line and a second state for take up of the fishing line. The guide member configured to engage the fishing line at a contact point and guide the fishing line to the spool from the contact point when in the second state. The guide member is configured to be driven to rotate to reciprocatively translate the contact point along a length of the guide member. The line guide mechanism is configured to transition the guide member between the first state and the second state in response to a user input.

Abstract: A baitcaster for retrieving a fishing line includes a spool, and a compound gear set. The spool is configured to be driven to take up the fishing line. The compound gear set includes a ring gear, first planet gears, second planet gears, and a second shaft. The ring gear is configured to receive an input torque from a first shaft. The first planet gears are driven by the ring gear. The second planet gears are driven by the first planet gears. The second shaft is driven by the second planet gears and is configured to drive the spool to take up the fishing line.

Abstract: A baitcaster includes a body, a spool, a handle, and a drive. The body defines a proximate end and a distal end opposite the proximate end.
