Using this Echonautics transducer is easy. First, make sure your vessel's hull deadrise is between 0° and 7°. Then, install the transducer through the hull using the 2.38 - inch hole diameter. Connect the 27 - foot cable properly. It can measure both depth and temperature. When using it, avoid high - drag situations as the transducer is designed to minimize drag. For maintenance, keep the bronze material clean and check the urethane acoustic window regularly for any damage. If you notice any issues with the NTC temperature sensor, it might need to be replaced. Also, make sure the connections are always tight to ensure accurate readings.
