Figure 20: Sample of Main Sonar Settings Tab
NOTE
For all sliders on the Main Sonar Settings tab, except the Power control, the new
settings will not be sent until the mouse has released control of the sliders.
5.7.1.1 Set the Range
The Range setting determines how far the SeaBat will “see”. The range settings are
operator selected. There are multiple settings in discrete increments. For the SeaBat
7125 ROV, these settings range from 5 to 300 meters (750 meters for 200kHz
operation).
Select the appropriate range scale to keep the horizontal bottom image at or above the
widest part of the sonar wedge:
Figure 21: Range Setting Diagrams
Diagram A depicts a proper range setting. Diagram B depicts an acceptable range
setting for a swath that is beginning to fade due to the effects of attenuation and
spreading loss. Diagram C depicts an incorrect range setting. Notice that the still-
useable ends of the swath are being cut off by the limits of the range setting.
For additional examples on incorrect range settings and possible solutions, see
