The GPS 150XL' s search and rescue function provides navigation guidance for
search and rescue operations, navigating in a ladder pattern to maximize coverage and
efficiency. This is done in reference to two waypoints called 'anchor waypoints'. The
first leg will be a specified distance from the line connecting the anchor waypoints.
This is called the 'offset distance'. The 'increment distance' is the distance between each
subsequent leg. The ladder can be created on either side of the anchor waypoints.
To perform a search and rescue operation:
1. Create a route of only two waypoints.

After activating a search and rescue, you will be informed with an 'Offset nav in
effect' message each time you traverse the route offset from the anchor waypoints and
the NAV summary page will guide you along each leg of the ladder pattern. Note that
bearing and distance information are referenced to the anchor waypoints. Once you've
arrived at the destination waypoint, the leg increment will be added to your present
offset, and the route will be automatically reversed. If a search and rescue is interrupt-
ed, note the parallel track direction (R or L) and distance on the catalog page for route
0. When you resume search and rescue operations, use this as the initial offset.
