Furuno NAVnet TZtouch2 User Manual

6. RADAR
6-23
The no.1 screen is independent of the no.2 screen when the no.2 screen is in stand-
by. However, when the no.2 screen goes to transmit state, so does the no.1 screen.
6.22 Bird Mode
The Bird mode sets up the radar for optimal detection of flocks of birds, which indi-
cates the presence of schools of fish. Automatic adjustment of gain, sea clutter and
rain clutter is suspended, and the equipment optimally adjusts those items according
the bird mode setting.
The radar settings are automatically adjusted to detect birds on the sea surface. Gain,
sea clutter and rain clutter are automatically adjusted to distinguish birds from noise,
to help you locate schools of fish more easily. Additionally, the bird mode can be used
to detect distant rain clouds.
The use of echo trail and echo average functions together with the bird mode make it
easier to distinguish bird echoes from other echoes. With echo average, echoes from
birds are emphasized. With true echo trails, moving vessels show long, steady trails.
Unlike those targets, bird echoes appear randomly and show random, short trails.
The bird mode has three settings according to the current level of sea clutter:
[Calm]: Suitable in calm conditions where sea clutter is weak. Applies low sea clutter
reduction to show weak bird echoes. When sea clutter is strong, bird echoes may be
hidden inside the sea clutter.
[Moderate]: Suitable where sea clutter is moderate. Applies medium sea clutter reduc-
tion.
