Discriminating Between The Sea Bottom And Fish Schools (White Line) - JRC JFC-130 Instruction Manual

< Discriminating between the Sea Bottom and Fish Schools (WHITE LINE)
You can reject signals (colors) in the order of descending signal intensity to

volume of a fish school. To monitor fish groups on and around the sea
bottom, set the white line to erase the strongest signal that represents the sea
bottom (reddish brown).

signals in descending signal strength order.
