A method is described to compute and display the line length required to troll a fishing rig at a desired depth. Line lengths and respective line angles measured at the surface are used to calculate an approximation to the actual underwater curve profile of the trolled fishing line, which is used to determine the line length required to troll at a desired depth or to determine the resulting depth for a specified line length. An embodiment is described which requires only a smartphone and software beyond standard trolling fishing equipment. This embodiment uses the embedded sensors of the smartphone to collect fishing line angle measurements. Also described is a method and devices to automatically collect the line angles and line lengths using a wireless fishing line inclinometer device and a wireless line counter, which is especially useful and convenient when software is implemented on a mounted marine electronics unit.

I provide a braking device attachable to a body frame having one bearing member that pivotally supports a spool and an operation means for rotating the spool, including another bearing member that pivotally supports the spool; a spool brake; a control board that controls the braking force of the spool brake; a battery that supplies power to the control board; and a cover member that covers the battery and the board.

A sensor assembly for a castable lure is provided including a pressure sensor configured to measure a water pressure applied to the castable lure when deployed in an underwater environment, a processor, and a memory including computer program code. The computer program code configured to, when executed on the processor, cause the processor to receive pressure data from the pressure sensor, correlate the pressure data with time stamp data, cause the pressure data and correlated time stamp data to be stored in the memory, determine a data connection status between a transceiver and a marine electronic device, and in response to determining that a data connection exists, cause the pressure data and the correlated time stamp data to be transmitted to the marine electronic device. The pressure data and correlated pressure data correspond to a depth profile for a cast of the castable lure.

A position controller for electronically monitoring the position and speed of a dredge. The position controller consists of an electric powered line winding spool with an electric encoder to indicate line speed and position to a microprocessor. A drag control assembly with electric control is used to increase, decrease or set the drag at desired setting by microprocessor control. Touch screen microprocessor interface is the preferred method to enter settings into the system and allow display/control through multiple preexisting marine electronic devices throughout a fishing boat.

A system for providing the location of a planer board is provided. In an embodiment, the system includes one or more computer devices and one or more computer processors. The system includes (A) a planer board application (planer board app) embodied in instructions stored by the one or more computer devices. When the planer board app is executed by the one or more computer processors, the planer board app is configured to: (i) receive inputs from a GPS locator module. The planer board app is further configured to receive user inputs for (ii) a lure line length for a planer board and (iii) a boat line length to the planer board. (B) The planer board app generates a planer board track based on the inputs from (i)-(iii). (C) The planer board app also includes a user interface, such that the planer board app is further configured to display the planer board track on the user interface.

A fishing system includes a submersible fishing implement for being received in a body of water and configured for capturing one or more fish. An implement driver is configured to drive movement of the submersible fishing implement through the body of water. A data collection system includes one or more sensors for sensing one or more fishing parameters and transmitting a fishing parameter signal representative of the one or more fishing parameters. A controller is operatively connected to the data collection system to receive the fishing parameter signal and to determine based on the fishing parameter signal a selected fishing location. The controller is further configured to transmit a navigation signal to the implement driver operative to control the implement driver to drive movement of the submersible fishing implement toward the selected fishing location.

An exemplary line retrieval apparatus is disclosed. The apparatus may comprise: a motor comprising an output shaft; a hand crank; a spool; and a driveshaft. The apparatus may further comprise a selector operable to shift the apparatus between, at least: a manual mode, in which the driveshaft is engaged with the spool and the hand crank such that rotation of the hand crank causes rotation of the spool; and a motor mode, in which the driveshaft is engaged with the spool and the output shaft of the motor such that rotation of the output shaft causes rotation of the spool. Related apparatus and methods are also disclosed.

The invention relates to measuring probe (100) for a spinning or casting rod (1) comprising a housing (101) with connection means (102a, 102b) on the housing (101) for securing the measuring probe (100) to a fishing line (2) of the rod (1) above the lure (3).
