Reel Wheel is equipped with hall effect sensors and a rotary encoder that will track the downrigger line-out distance and measure its angle relative to the water. Designed to fit Scotty downriggers, the Reel Wheel is a modification added to the existing pulley wheel located at the end of the boom.
Reel Wheel Enclosure
The Reel Wheel enclosure houses the rotary encoder and the wiring to connect and protect the encoder and the hall effect sensors.
Enclosure
This enclosure is a 3D-printed case designed to fit over the existing downrigger parts. Its made from PETG to provide water resistance and durability.
Rotatory Encoder Setup
Rotary Encoder
A rotary encoder provides high precision measurements giving the angle of the downrigger line relative to the water.
Shaft
The 3D-printed shaft connects and locks securely between the boom and the encoder without slipping.
Reel Wheel Pulley
Reel Wheel pulley is a reimagining of the standard downrigger pully cover to allow for the integration of hall effect sensors. A magnet array is then mounted on the pulley wheel to track the rotations.
Magnetic Ring Array
Four magnets give the RDB line length precision to the quarter rotation of the pulley.
Hall Effect Sensors
Hall effect sensors mounted into the pulley cover plate track the rotations of the pulley wheel by detecting the magnets passing underneath.
