To open a zoom window, click the Zoom windows button in the tool bar, then click a target of interest in the sonar view.
The zoom area (A) in the sonar view is a fixed size and cannot be adjusted. However, you can move the zoom area to another
location with the cursor. The images in the true zoom windows (B) are acquired separately using high-resolution sampling parameters and adequate transmit
pulses.
If you record sonar data while the zoom windows are open, the zoom window data will also be recorded for replay. During playback,
the zoom windows will open automatically.
