A fishing rod including a rod body, a free line cast control and drag mechanism operatively connected to a proximal end of the rod body, and a line operatively threaded through the free line cast control and drag mechanism and running through a hollow passageway of the rod body and out a distal end. A method of fishing with the fishing rod by casting the line out of the distal end of the rod body onto a body of water, detecting that a fish is on the line, and pulling the line through the proximal end of the rod body and through the free line cast control and drag mechanism.

A fishing rod that includes an elongated, tapered rod blank at least a portion of which is quadrilateral in cross section, the quadrilateral portion of the rod blank diminishing in cross-sectional area toward a tip end of the rod blank, the quadrilateral portion of the rod blank comprising a sandwich-structured composite of a core disposed between facings, the core less dense than the facings, the quadrilateral portion of rod blank less stiff in a casting direction than transverse to the casting direction; fishing line guides mounted at intervals along the length of the rod blank; a reel seat mounted at the base end of the rod blank; and a handle mounted at the base end of the rod blank adjacent to the reel seat.

Provided herein is an on-line multiplayer gaming system to score real-world angling events of multiple players. The system includes a first angling event sensing device, processor, and a gaming application on a first mobile device in communication with a recreation monitoring platform. The system further includes a second angling event sensing device, processor, and a second gaming application on a second mobile device in communication with the recreation monitoring platform. The recreation monitoring platform calculates scores for the first and second player based on data from their respective angling event sensing device.

An underwater drone is disclosed. The underwater drone includes a horizontal propeller module and a vertical propeller module to respectively provide a drone body with a horizontal proceeding force and a vertical lifting or diving force. The underwater drone includes a horizontal channel and a vertical channel, which allow the water to pass through for reducing resistance when the underwater drone moves forwards, upwards or downwards. The underwater drone is equipped with a buoy member with an antenna portion of a communication module disposed therein. The underwater drone is equipped with the fishing device, the fish finding device and the image capturing module. Therefore, the underwater drone is capable of fishing, rapidly moving and wireless remote control.

A water-activated bobber release device has a housing, a bobber assembly, a spool and a line, a bobbin assembly with a dissolvable tablet, a screw extending through a central hole in the bobber assembly and a center hole in the dissolvable tablet of the bobbin assembly, and a cap with an aperture and a valve between the aperture and the bobbin assembly. The screw engages the bobbin assembly and a threaded fastener to compress a spring. When the device is submerged in a body of water at a certain depth, the pressure opens the valve to allow water to enter. The water dissolves the tablet which collapses the bobbin assembly, and the spring forces the bobber away from the housing. Once released from the housing, the bobber is free to float to the surface of the water allowing for the retrieval of the submerged item attached to the housing.

A fishing accessory for preventing the tangling of a fishing line on a fishing pole comprising a base attachable to the fishing pole and an adjustable guide member. The adjustable guide member is movable from a first position wherein a portion of the guide member contacts a guide surface of the base to a position wherein the portion of the guide member is positioned distant from the guide surface. The fishing accessory includes an adjustment member extending from the guide member engaged with an opening in the base wherein moving the adjustment member in one direction moves the guide member away from the guide surface and moving the adjustment member in the opposite direction moves the guide member closer to the guide surface. The position of the guide member is adjustable toward and away from the guide surface to accommodate a specific diameter fishing line.

A fishing line guide guiding a fishing line is attached to a rod body of a fishing rod. The fishing line guide includes a ring holding portion and a first support leg portion extending from the ring holding portion. The ring holding portion includes an inner peripheral portion, an outer peripheral portion, and an annular portion extending in a circumferential direction between the inner and outer peripheral portions. The ring holding portion is coupled to a guide ring at the inner peripheral portion. The first support leg portion has a pair of lateral surfaces connecting with the outer peripheral portion. The ring holding portion includes a pair of twisted portions which form a portion of the outer peripheral portion and a portion of the annular portion and are twisted respectively from the annular portion toward the lateral surfaces of the first support leg portion to the outer peripheral portion.

A fishing rod vibration system, including a mounting platform, a batter powered electronics system mounted on the mounting platform and including a motor controller and a user interface operably and electrically coupled to the motor controller, as well as a vibrator selectively and detachably coupled to the electronics system for receiving output signals from the motor controller. The vibrator includes a housing enclosing an electric motor, and vibrator mounting elements enable attachment of the vibrator to a fishing rod.
