bottom contour and composition, as well as depth directly below
the transducer.
When in the water, the transducer (SP100 or SP200/SP300) sends a
sound wave signal downward and determines distance by measuring
the time between the transmission of the sound wave and when the
sound wave is bounced off an object. Then it uses the reflected
signal to interpret depth and composition of an object or bottom
structure.
