1. You will see a deep blue line and the letters FS za for frequency switch in the center of the water column at the point in the data when you make a frequency change You also have the option of selecting None in the dropdown list Just recall that if no transducers are selected the system cannot collect data Speed Control The Sea Scan Survey software maintains a constant 1 1 aspect ratio for the SONAR image This is possible by setting the ping rate based on the current range and the SOG The spacing of each vertical line on the screen is equivalent to a known distance for each of the ranges Sea Scan Survey sets the transducers to ping at these interval distances so the resulting image has a 1 1 aspect ratio The time between each of these known distance intervals depends on the SOG The time interval is set based on apparent speed When a discrepancy appears between the current SOG and range Sea Scan Survey will make SOG corrections on a ping by ping basis Using an accurate estimate of the vessel s SOG you can determine the time interval between each ping event An externally supplied SOG is used to set the software s internal apparent speed automatically When the SOG information is not available externally you can manually match the apparent speed to the vessel s actual SOG to maintain the constant 1 1 aspect ratio for the image Depress the Manual or Auto SOG buttons on the SONAR Control Window lf you set for Manual
