Zoom & Bottom Track & Bottom Lock
(Split Screen displays)
When using the Chart display , the Twinscope can also
display a split screen high resolution zoom of any 25% of
the depth range, or can show a split screen Bottom Track
or Bottom Lock display. The high resolution Zoom is
very useful when looking for extra detail on the bottom or
in areas above the bottom. Because the
Twinscope uses
an Interphase unique 4X over-sampling technique, the
zoom actually shows more data than the non-zoomed
picture. Fishermen have long used the bottom locking
features when fishing over a rocky bottom or when fishing
in rough surface conditions. In the
Bottom Track mode,
a zoomed view of the bottom is shown on the left side of
the split screen display. Regardless of changes in bottom
depth, the left side tracks it and keeps the zoomed bottom
picture in view. In the
Bottom Lock mode, the bottom is
forced to appear as a straight horizontal line across the
bottom of the left side of the LCD while any targets close
to the bottom are displayed above the bottom line. Over
rough bottoms or in rough conditions, this feature is
extremely useful to eliminate rapidly changing bottom
depths from the display and to show only suspended
targets close to the bottom.
Press the soft key labeled " ZOOM

" to activate the split
screen high resolution zoom function. The left side of the
LCD screen now shows the zoomed area, while the right
side continues to show the conventional depth display.
