Generally, any Garmin transducer can be used with any recent Garmin Fishfinder, Sonar Module, or Chartplotter with a built-in sonar module. The NMEA Sensors listed below, however, can only be used with corresponding NMEA-compatible devices. Choose the transducer or sensor that best suits your needs. Transducer kits come with installation instructions. Please follow these instructions carefully to ensure proper operation.
• Sensors contain an integral data processor, and only require electrical power to output NMEA data which can be displayed on any chartplotter screen
• Transducers only provide raw data, and must be connected to a processor (usually a depth sounder with a display, or a “black box” sonar module) in order to display depth, speed, etc. Depth transducers are commonly available in160 /235 KHz (deep/shallow water) and 200 KHz (shallow water, less than 600 ft.) models
• Transducers with 0° of element tilt must be mounted so they point straight down; if the hull is curved or angled, they often require fairing blocks to achieve this. Transducers showing a range of element tilt angles (relative to the hull) can be set to a particular angle within that range at the time of installation. This can eliminate the need for using a fairing block when mounting on a curved or angled hull
• Hull material: wood - use a bronze transducer
• Hull material: fiberglass - use any transducer material
• Hull material: aluminum - use a plastic transducer
