Choose a transducer compatible with the Raymarine Series product you own; see table. Transducer kits come with installation instructions. Please follow these instructions carefully to ensure proper operation.
• Transducers only provide raw data, and must be connected to a processor (usually a depth sounder with a display, or a black box module) in order to display depth, speed, etc.
• Replaceable/removable paddle wheel in speed transducers
• Hull material: wood - use a bronze transducer
• Hull material: fiberglass - use any transducer material
• Hull material: aluminum - use a plastic transducer
