Vertical presentation mode - can be set in any direction. Shows 60° vertical distribution of the school (90°/180° as option).
Multi frequency from 20-30 kHz gives longer detection range and larger search area.
Vertical and horizontal beams allow to view the target from above and from the side at the same time.
Beam stabilization provides with accurate target representation independent of the vessel movement.
Simultaneous tracking of three targets, compare schools by area and volume estimation.
