Furuno CSH-53 manual NET Shoot

Menu	Item	Description
NET SHOOT	Net Diameter	Sets estimated ship's turn diameter necessary
PLAN		for shooting net, to get accurate depiction of
		net location mark, which you can display by
		pressing the NET COURSE key. The setting
		range is 200 to 1000 meters in 10 meter steps.
	Tilt Interlock	Choose ON to interlock diameter of net
		location mark with tilt angle. When you lower
		the tilt angle the on-screen net location mark
		enlarges. (For example, the net diameter is set
		for R meters. When the tilt angle is 45° the
		diameter of the on-screen net is 2 R meters.)
NET SONDE	Net Sonde XMTR	Enter number of net sonde transmitters and
		their distances between each other.
	Net Length	Enter net length. The setting range is 500 to
		3000 meters in 100 meter steps.
	Wire Length	Enter wire length between own ship and net.
		The setting range is 100 to 1000 meters in 100
		meter steps.
	Net Width	Enter net width. The setting range is 0 to 100
		meters.
NET PLOT CORR	Layer 1	The movement of the net during net shooting
	Layer 2	is plotted by using water current speed and
	Layer 3	direction fed from external sensor. The
		external sensor feeds that data for three depths
		(layers), thus net movement will be different
		at each layer. Determine degree of difference
		among layers considering net, sea conditions,
		vessel construction, etc. If 50% is set, for
		example, on-screen net moves at speed of
		50% of water current speed.
