Glossary of terms
Alarms – can be set to sound a “beep” if the echosounder detects a target above
(shallower than) a minimum alarm depth or below (deeper than) a maximum
alarm depth. The EQXX allows you to set the alarm depths and to enable or
disable both the minimum and maximum depth alarms.
A-Scope – a method of displaying the echosounder information. In A-Scope
mode, the echoes are displayed in a “bar-graph” format, with stronger echoes
displayed not only in the color representing their target strength, but also in a
width representing their target strength.
Color threshold – the color threshold function allows the “weaker” targets and
noise which may be shown on the display screen to be eliminated from the
display. These targets are usually shown in the weaker target colors such as blues
and greens. The Color threshold allows you to choose not to display the blues, or
the blues and greens, etc. Doing this will leave only the stronger targets on the
display screen.
) The monochrome version dual station will have 3 different tones of gray.
Configuration – the configuration functions of the EQXX allow you to adapt the
system more specifically to your needs. You may set Units of measure (feet,
fathoms, meters, etc.), Background color, Menu language, Scroll speed, etc.
Depths – DK = Depth below keel, DS = Depth below surface, DT = Depth below
transducer.
Echogram background color – is the color shown on the EQXX in the event no
target is present. There are three colors to choose from: white, blue or black,
where black is especially useful during nighttime operation.
Echosounder frequency –38kHz,50kHzor200kHzcanbeselectedtosuitthe
task. 200 kHz is for general purpose and offers optimum discrimination and a
narrow transmitter beam. 38 kHz and 50 kHz are for searching in a wider area,
determining bottom conditions and going the deepest.
Event marker –pressingthe
[EVENT]
key will set a vertical marker on the
screen at the current echo (ping) to indicate a school of fish, etc. The echo-
sounder can send out WPL via NMEA for automatic plotting of the event-
