The sonar can continuously or part-scan a full 360° sector in either direction. Typically, side-to- side scanning would be used for scanning a seabed while 360° scanning would be appropriate in a cave passage.

How are caves surveyed?

Traditional survey methods use measuring tapes, compasses, and clinometers to establish traverse lines. The representation of the cave is attached to the traverse line by hand sketching within the cave. Maps were then drawn by plotting the traverse line and using the in-cave sketches to draw the cave.
