Systems and methods are disclosed herein for providing a fishing rod and reel assembly with an easily adjustable rod balance adjustment. The system includes a fishing rod having a handle section. Positioned adjacent to the handle section is a reel seat body section along which a reel seat frame may securely hold a reel at substantially any position along the reel seat body section to achieve the desired rod balance. Also, the system and method include being able to securely mount and hold a reel to the rod at any position along the reel seat body to achieve any desired balance point location. Thus, a fisher may change reels, spools, line weights, bait, lures or the like and quickly rebalance the rod and reel assembly for an optimal fishing experience.

A grip assembly configured for fixing a reel to a fishing rod includes a front seat grip non-movably fixable to a fishing rod, a gear rack on the front seat grip, a sliding grip movably fixable to the fishing rod and configured to slide in an axial direction of the fishing rod so as to selectively engage the front seat grip, a lever pivotally connected to the sliding grip, and at least one tooth provided on the lever. When the lever is actuated from an open position to a locked position, the at least one tooth engages the gear rack and the lever pulls the sliding grip toward the front seat grip on the fishing rod.

A rotatable fishing rod handle device with adjustable bending and straightening includes a handle body, a wheel seat and a connecting rod, wherein a front end portion of the handle body is provided with a mounting hole inwardly. A rear end portion of the wheel seat is provided with a coupling shaft. The coupling shaft is located and rotatable in the mounting hole. A shaft body of the coupling shaft is provided with a groove, in which a latch protrusion and a spring are disposed. An end of the latch protrusion protrudes outward to a notch of the groove and the latch protrusion is elastically disposed in the groove through the spring. A first position limiting hole is formed at a position corresponding to the groove on the coupling shaft on a side wall of the handle body.

Methods and apparatus for expanding a rod from a collapsed position to a formed position are disclosed. One such apparatus includes a plurality of segments for forming the body of the collapsible rod including with each segment coupled to each immediately adjacent segment of the plurality of segments. The apparatus may include a coupler for coupling each segment of the plurality of segments to each immediately adjacent segment of the plurality of segments. The coupler may stretch from a base segment to the tip of the apparatus and may be biased to apply a force to hold the plurality of segments in a formed position and to urge the plurality of segments into a formed position from a collapsed position. In the formed position, the plurality of segments may be aligned end-to-end to form a rod and in the collapsed position, the plurality of segments may be folded against each other such that cylindrical walls of each of the plurality of segments are positioned adjacent each other.

A fishing rod has a rod portion and a handle portion separated by a reel seat. At least one portion defines a magnet receiving area, which may be external or within a hollow portion that is surrounded by a wall and that is located in the rod portion, the reel seat portion, or in the handle portion for receiving a spacer piece. The spacer piece may be cylindrical shaped and made of foam. The spacer piece defines a receiving cavity for receiving a magnet. In one embodiment, the receiving cavity is asymmetrically oriented in the spacer piece such that the receiving cavity has a close side that is a first distance from the wall and has a far side that is a second distance from the wall for locating an area of best magnetic attraction at a predetermined location on an exterior of the rod portion or handle portion.

The present disclosure relates to systems and methods for balance index determination. For example, a wearable apparatus may have at least one gyroscope configured to measure angular velocity about a first axis; at least one inertial measurement device (IMU) configured to measure deviation along a second axis and a third axis; at least one memory storing instructions; and at least one processor configured to execute the instructions to: receive angular velocity measurements over a period of time from the at least one gyroscope; receive deviations from the second axis and from the third axis over the period of time from the at least one IMU; weight the deviations based on directions associated with the deviations; and generate a composite balance index based on the angular velocity measurements, the weighted deviations from the second axis, and the weighted deviations from the third axis.
