The Garmin Handheld 72 navigator is designed for outdoor use on both land and water. It is popular among kayakers and boaters due to its moisture-proof casing that also enables it to float in water. The Garmin Handheld 72 comes pre-loaded with land points, and is enabled with aviation accuracy to provide positioning data to within 3 meters. it also features city and street maps, water markers that include buoys and channel markers, and s tide and current information.
Difficulty: Moderately Easy
Initialize the GPS 72 receiver by turning it on, and taking it outside to an area away from structures in order to establish its starting position. The message "3D GPS Location" will be displayed when the unit is ready to use for land or sea navigation.
Mark "Home" by selecting the "Waypoint" menu option, and typing in a descriptive term such as "Home" or "Start."
Input your destination by selecting the "Waypoint" menu button and entering a latitude and longitude position through manual keypad input, or selecting a known city, street and address. Press "Enter" when complete. Save the position with a descriptive term for future reference.
Start walking or boating in the direction of the destination. The Garmin 72 will work only when moving. Change direction to the left or right until the GPS compass is pointing to the center. When you get close to the destination, an audible alert will state, "Arriving at destination."
Tips & Warnings
Unlike a car GPS, the Garmin 72 uses inertial navigation, which calculates the dead-reckoning position, and requires the unit be in motion to provide up-to-date position information and direction.
