VRM (Variable Range Marker)

This is a circular-shaped marker whose size can be changed as desired. You can use this marker

when you want to examine the distance of an echo from your ship.

When measuring the distance of an echo from your ship, be sure to measure at a point close to the

center of the echo image on the screen.

EBL (Electronic Bearing Line)

This is a marker shaped like a straight line segment that can be changed to any direction centering

around the ship’s position. Use this marker to examine the advancing direction of your ship and its

relative angle with an echo. When measuring the angle of an echo, position the marker at the center of

the echo.
