can send signals up to 60 times per second, as well as produce the varying levels of
power output needed for different depths and conditions. Additionally, the transmitter
has the capability to create very precise sonar pulses needed for a high degree of target
separation. Humminbird® receivers are extremely sensitive, but within a narrow
"bandwidth" to discriminate against noise from external sources. Additionally, the
receiver offers a wide "dynamic range" which provides the ability to receive very strong
signals alternating with very weak signals, without the strong signal overwhelming the
weak signal. See Transducer and Noise.
TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for
Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to
activate the feature. TripLog appears on the Big Digits View, and can be reset to zero
through the TripLog menu.
TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not
artificial arches or symbols. Humminbird® units are capable of producing fish arches due
to the wide 60° sonar beam of DualBeam PLUS™, an extremely sensitive sonar receiver.
See Fish Arch.
Viewing Angle: Viewing Angle is an attribute of an LCD that characterizes visibility of the
display when viewing from off the central access, such as when standing to the side of
the fishfinder. Wider viewing angles are better because the information remains visible
even when viewing from the side.
WhiteLine®: WhiteLine® is a Humminbird® feature that highlights the strongest sonar
return on the display using a very light gray band. This is preferred by some anglers who
have grown accustomed to the feature on paper graph chart recorders.
WideSide®: WideSide® is a Humminbird® sonar configuration used in an optional
transducer. WideSide® uses three sonar beams pointing to the left, right and down.
Beams pointing to the left and right are effective for spotting fish and structure near the
surface or on the bank. The downlooking beam provides depth information directly
below the boat.
X-Press™ Menu: X-Press™ Menus are a Humminbird® feature that make the most
commonly-used menu selections available with one press of the MENU key. Items
that appear on the X-Press™ Menu are related to the current view, and present the
most logical choices for that view. Sonar View X-Press™ menus will differ from Chart
View X-Press™ menus, etc. X-Press™ menus are one of the principal reasons that
Humminbird® products are easier to use.
