The Simrad EY60 portable scientific echo
sounder is ideal for both fixed and mobile configurations.
typical mobile survey will involve both vertical and horizontal orientation
of the acoustic beam to be able to monitor fish distribution in the
whole water column. Monitoring fish migration in rivers normally
involves one transducer with the acoustic beam pointing horizontally
from one the other side of the river.
Reflection of sidelobes from the surface
and the bottom is a common problem in shallow waters, especially during
The new composite transducer series (70,
120, 200 kHz) are beneficial in shallow water environments due to
its low sidelobes. Alternatively, our elliptical transducers are particularly
suited for fixed location horizontal monitoring of fish movement.
