Pre-Programmed Screen Displays
Rather than ask you to “build” different screen displays while
operating the unit, the Advantage has seven of the most
valuable LCD screen displays pre-programmed into its
operating system memory. Thanks to the Multi-Tasking
operating system, each of these pre-programmed displays
(known as Views) are always being updated, regardless of
which screen display is presently being used. This means, for
example, that the two Track Plotter’s will continue to plot and
update your vessel’s position - even while you’re looking at a
Zoomed picture of the bottom! Similarly, even while viewing
your vessel’s position on one of the Track Plot displays, the
digital and graphic depth screens are simultaneously being
updated in the background - ready for immediate access. And,
thanks to the lithium battery memory backup, as described in
the next section; ranges, gain, zoom and other settings are
remembered as you go from View to View and are even
remembered when you turn the unit off.
Internal System Memory
There is nothing so frustrating as having your depth sounder
re-start when you start your boat’s engine and having to
completely re-set the range, gain, contrast and all your other
settings. Because the Advantage contains an internal lithium
memory battery, it remembers all system settings with the
power removed. When you turn your Advantage on, it will
immediately start in the last View that you used, complete with
the proper range, zoom, gain and other important settings.
Instead of using a non-volatile RAM, a lithium battery was
used to ensure a long error-free memory life. Most non-
volatile RAM’s exhibit increasing errors with time and can
become a serious problem after only 100,000 operations.
Cold Cathode back light
The Advantage has the best LCD back light system available.
It uses a Cold Cathode Fluorescent lamp (CFL) with
exceptionally long life characteristics which greatly exceed the
more common electro-luminescent and incandescent bulb back
light. In addition to its exceptional reliability, the cold cathode
lamp provides a much more visible display than other back
light systems. Screen clarity and contrast are greatly
enhanced. The typical half-life (when output brightness
diminishes to 1/2 its original value) of the cold cathode back
light is in excess of 20,000 hours. A typical electro-
luminescent panel, for comparison, has a half life of only 2,000
hours!
