3. How FLS Technology Works

Sonar Beam

The EchoPilot 3D is a unique and patented invention. It can see through a full arc of 90 degrees,

from straight ahead to straight down.

The transducer has a horizontal beam of 60 degrees (port to starboard).

Distance Ahead

The distance ahead that the FLS can see depends on the depth of water below the vessel, and the

laws of physics. The transmit 'ping' radiates at all angles down and out from the vessel, hits the

seabed and some of it is returned to the transducer's receivers.

As the 'ping' travels further away from the boat, it hits the sea bed at an increasingly acute angle.

At a certain point the angle will be so acute that the 'ping' is not returned, and the seabed

information is lost - this determines the maximum view ahead.

When on a flat muddy bottom (e.g. river or estuary) the FLS will show the seabed up to ten times

the depth away from the boat. This ratio increases if the seabed shoals upward. Rocky bottoms are

better targets than muddy ones, and hard vertical surfaces like quay walls, rocks or coral reefs will

often be seen at considerable distances.
