TRANSDUCER COVERAGE
The area covered by the transmitted sound waves is deter-
mined by the cone angle of the transducer and the water depth.
Using
G
s
standard 20° transducer, the coverage is approx-
imately 1/3rd of the water depth. As shown in Example 1, the
coverage area at a 30 foot depth is approximately a 10 foot diam-
eter circle. The scale below illustrates how coverage increases as
depth increases.
