EQ42/50/52 Principles of operation Chapter 8

The center of the sound beam is the most intense, then as you move out towards

the sides of the sound beam there is a point where the intensity of the sound is

half what it was in the center. The distance moved is the “beamwidth”.

See Figure 3.

8.2.2 Effects of the vessel’s speed

The display of fish on the EQXX depends directly on the vessel’s speed, as well

as on the depth of the fish. When the vessel is at rest, the echo traces will appear

stretched and flattened. As the vessel’s speed becomes greater, the echo traces

will become shorter and more arched. The reason for this change in appearance is

that as the vessel speed increases fewer number of sound “pings” strike each fish.

A low vessel speed will provide the most accurate information of where fish are

located.
