Smaller targets may be ignored if there is a lot of noise in the area, as the system will track the strongest echo within the track window. · Wind direction: The wind marker is show in the outer area of the echo presentation as a white arrow. This arrow can be manually adjusted for indication of the wind or current direction, or automatically show the wind direction if a wind sensor is connected. It is only a read-out of the current wind speed providing that a wind sensor is connected. If the Scientific Output function has been implemented, this Wind speed button is replaced with the Scientific Output button. · Scientific Output: This is an optional functionality designed to be used when the sonar is used for scientific purposes. When enabled, the sonar will provide special information on an ethernet port.

However, the transducer face should be inspected and cleaned when docking. Note Do not paint the transducer array with traditional hull plating paint. Do not use metal tools or high pressure water on the transducer array. Procedure 1 2 Ensure that the distance between the vessel hull and the bottom of the dry dock is sufficient to lower the transducer array.
