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 options 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.
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.
