4.2 Transducer Deployment Methods
The sonar transducer must be submerged in water to function correctly. Ensure there are no air bubbles between the transducer and the water. The transducer can be deployed in several ways:

Image: Visual guide demonstrating various methods for deploying the sonar sensor, including using the float, ice fishing setup, mounting to a boat hull, and attaching to a pole.
- Using the Float: Attach the transducer to the provided float and cast it into the water. Ensure the transducer is fully submerged and hangs vertically.
- Ice Fishing: Place the transducer directly on the ice surface if the ice is clear and smooth, or submerge it into a hole drilled in the ice. Ensure good contact with the water.
- Fixing to a Boat Hull: Use the fixing frame to mount the transducer to the boat hull. Ensure the transducer is below the waterline and free from obstructions.
- Using a Pole: Attach the transducer to a pole and submerge it into the water from the side of a boat or dock.
The transducer cable is 25 feet (approximately 7.6 meters) long, allowing for flexible deployment.
