Abstract

Various implementations described herein are directed to a trolling device having a motor with a propeller coupled to the motor and a shaft configured to couple or mount the motor to a watercraft. The trolling device may include a housing encapsulating the motor, and the housing may include a nosecone having a transducer array incorporated within the nosecone.

First claim

What is claimed is:

1 . A device, comprising:
a motor; a propeller coupled to the motor; a shaft configured to couple the motor to a watercraft; and a housing encapsulating the motor, wherein the housing comprises a nosecone having a transducer array incorporated within the nosecone.

2 . The device of claim 1 , wherein the transducer array is configured for imaging an underwater environment below the surface of a body of water in which the device is deployed.

3 . The device of claim 1 , wherein the motor comprises an electric motor configured to drive the propeller to provide thrust for the watercraft in a body of water during operation of the electric motor.

4 . The device of claim 1 , wherein the housing encloses the motor within a waterproof capsule impervious to water.

5 . The device of claim 1 , wherein the shaft is configured to rotate relative to the watercraft to steer the watercraft in a body of water during operation of the motor.

6 . The device of claim 1 , wherein the shaft is configured to rotate the housing relative to the watercraft to thereby rotate the nosecone at least 360° for imaging a 360° view of an underwater environment below a surface of a body of water.

7 . The device of claim 1 , wherein the shaft comprises at least one electrical cable for controlling operation of the motor, wherein the operation of the motor is controlled electrically or mechanically via user input.

8 . The device of claim 1 , wherein the shaft comprises at least one electrical cable for controlling operation of the motor, wherein the operation of the motor is controlled by a computing device.

9 . The device of claim 1 , wherein the shaft comprises at least one electrical cable for transmitting sonar data signals from the transducer array to a computing device.

10 . The device of claim 1 , wherein the transducer array comprises a spotlight transducer array having multiple scanning transducers.

11 . The device of claim 1 , wherein the transducer array comprises multiple transducer elements having one or more of a right scanning transducer, a left scanning transducer, a down scanning transducer, and a conical down beam transducer.

12 . The device of claim 1 , wherein the housing comprises a hydrodynamic contour.

13 . A trolling motor, comprising:
an electric motor having a propeller coupled thereto; a steering shaft configured for coupling the electric motor to a watercraft; and a housing encapsulating the electric motor, wherein the housing comprises a nosecone having a transducer array incorporated within the nosecone.

14 . The trolling motor of claim 13 , wherein the transducer array is configured for imaging an underwater environment below the surface of the body of water in which the trolling motor is deployed.

15 . The trolling motor of claim 13 , wherein the transducer array comprises a spotlight transducer array having multiple scanning transducers.

16 . The trolling motor of claim 13 , wherein the transducer array comprises multiple transducer elements including one or more of a right scanning transducer, left scanning transducer, a down scanning transducer, and a conical down beam transducer.

17 . A system, comprising:
a trolling device configured to be coupled to a watercraft, having:
a motor having a propeller coupled thereto,
a housing enclosing the motor within a waterproof capsule, the housing having a nosecone with a transducer array incorporated therein, and
a steering shaft configured for coupling the housing to the watercraft, the steering shaft having a first electrical wire for transmitting sonar signals from the transducer array; and
a computing device electrically coupled to the trolling device via the first electrical wire, comprising:
a processor;
memory having instructions that cause the processor to:
record sonar data associated with the sonar signals received from the transducer array via the first electrical wire.

18 . The system of claim 17 , wherein:
the steering shaft comprises a second electrical wire electrically coupling the motor to the computing device for controlling operation of the motor, and the instructions further cause the processor to transmit control signals to the motor via the second electrical wire for controlling operation of the motor.

19 . The system of claim 17 , wherein the transducer array comprises a spotlight transducer array having multiple scanning transducers.

20 . The system of claim 17 , wherein the transducer array comprises multiple transducer elements including one or more of a right scanning transducer, left scanning transducer, a down scanning transducer, and a conical down beam transducer.
