that the receiver interprets. Transducers are available for many specific mounting
applications for the boat, such as a transom mount, trolling motor mount, etc.
Humminbird® offers many sophisticated transducers, often with multiple piezo
electric elements designed to form specifically-shaped sonar beams, providing the
angler with superior tools for finding and catching fish. See Transmitter and SONAR.
Transmitter: The transmitter and receiver are matched parts of the sonar system
that send (transmit) and listen to (receive) the sonar signals, and work in
conjunction with the transducer. Humminbird® transmitters have an extremely fast
cycling design that 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, as
opposed to artificial arches or symbols. Humminbird® units are capable of
producing fish arches due to the extremely sensitive DualBeam PLUS™ sonar
receiver with its wide 60° sonar beam. 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 axis, 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: The X-Press™ Menu is a Humminbird® feature that makes 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.
Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide
enhanced resolution. With enhanced resolution, the angler can more easily see fish
hanging in structure or multiple fish hanging close together. Split screen zoom
divides the display into the full range view on the right, and the zoomed view on the
left. Humminbird® offers One-Touch® Zoom which allows the zoom feature to be
easily accessed from the regular sonar view with just one key press, eliminating the
need to use menus to access the feature.
Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area
just above the bottom to provide enhanced resolution. Unlike regular zoom, it
continuously graphs the bottom at a constant point on the display regardless of
changes in depth. This "flattens" out the bottom contour, but is effective at showing
fish on or near the bottom, and is preferred by many saltwater anglers.
