Inspection views
The SN90 system offers five inspection beams. Each inspection beam is presented using
an Inspection view. If you use several Inspection views, you can train and tilt the beams
individually, and independent of the beams displayed in the other views.
You can use the Inspection view to study single fish, schools and bottom conditions in
detail. The echo presentation in the Inspection view resembles the echogram you see
on an echo sounder. The Inspection view can be regarded as an "echo sounder" with
an adjustable direction.
You can train and tilt the beam independent of the beams displayed in the other views. To
change the bearing of the Inspection view, use the function on the menu.
Bearing Main
You can also click on the solid bearing line in the Horizontal view and drag it.
