Glossary Sonar Terms <strong>GPS</strong> & Navigation Terms<br />
Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide<br />
enhanced resolution. With enhanced resolution, the angler can more easily see fish<br />
hanging in structure or multiple fish hanging close together. Split screen zoom<br />
divides the display into the full range view on the right, <strong>and</strong> the zoomed view on the<br />
left. <strong>Humminbird</strong>® offers One-Touch® Zoom which allows the zoom feature to be<br />
easily accessed from the regular sonar view with just one key press, eliminating the<br />
need to use menus to access the feature.<br />
Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area<br />
just above the bottom to provide enhanced resolution. Unlike regular zoom, it<br />
continuously graphs the bottom at a constant point on the display regardless of<br />
changes in depth. This "flattens" out the bottom contour, but is effective at showing<br />
fish on or near the bottom, <strong>and</strong> is preferred by many saltwater anglers.<br />
Acquisition Time: The length of time that a <strong>GPS</strong> receiver typically takes to<br />
determine a position from at least three satellites. <strong>Humminbird</strong>® <strong>GPS</strong> receivers<br />
provide very fast acquisition times (under one minute), permitting users to get<br />
out on the water faster.<br />
Alarm, Arrival: The audible alert that sounds when the boat is equal to or less<br />
than the alarm setting (25 feet – 3000 feet) from the location of the destination<br />
waypoint.<br />
Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal<br />
to or over the alarm setting (25 feet – 3000 feet) from the location where the<br />
alarm was turned on.<br />
Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the<br />
boat’s distance from the intended Track, (Cross Track Error), is equal to or over<br />
the alarm setting (25 feet – 3000 feet). See Track <strong>and</strong> Cross Track Error.<br />
Altitude: Altitude measures height above sea level. Altitude is a measurement<br />
that can be provided by <strong>GPS</strong>.<br />
Bearing (BRG): Bearing is the direction to a destination waypoint measured in<br />
degrees from North (i.e. 321°, where 000° is North, 090° East, 180° is South,<br />
270° is West).<br />
Chartplotter: Chartplotter describes a navigation device that shows Present<br />
Position on a Map, along with Tracks, Waypoints, <strong>and</strong> Routes. All Chartplotters<br />
are also considered Trackplotters. All <strong>Humminbird</strong>® <strong>GPS</strong> Combo units are<br />
Chartplotters. See Trackplotter.<br />
