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.
GPS & Navigation Terms:
Acquisition Time: The length of time that a GPS receiver typically takes to determine a
position from at least three satellites. Humminbird® GPS receivers provide very fast
acquisition times (under one minute), permitting users to get out on the water faster.
Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than the
alarm setting (25 feet–3000 feet) from the location of the destination waypoint.
Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to or over
the alarm setting (25 feet–3000 feet) from the location where the alarm was turned on.
Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the boat’s
distance from the intended Track, (Cross Track Error), is equal to or over the alarm setting
(25 feet – 3000 feet). See
Track and Cross Track Error .
Altitude: Altitude measures height above sea level. Altitude is a measurement that can
be provided by GPS.
Bearing (BRG): Bearing is the direction to a destination waypoint measured in degrees
from North (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West).
Chartplotter: Chartplotter describes a navigation device that shows Present Position on
a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are also considered
Trackplotters. All Humminbird® GPS Combo units are Chartplotters. See
Trackplotter .

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.
