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 in 50/200 KHz (deep/shallow water) and 200 KHz (shallow water, less than 600 ft.) models
