Understanding Transducer Coverage
The bottom area covered by the transmitted sound waves
is determined by the beam width of the transducer and the
water depth. The Fishfinder can transmit either a narrow or
wide beam.
The narrow beam provides crisp bottom and structure
detail, but the coverage area is limited. As shown in the
following illustration, at a 30-foot depth, the narrow beam
covers the area of a 6-foot circle.
The wide beam covers a much larger area, but with some
loss of bottom and structure detail. In the following
illustration, at a 30-foot depth, the wide beam covers the
area of a 20-foot circle.
