Offsets
This icon leads to Offset reading screens with options for keyed-in offsets as well as offsets taken by laser devices.
These devices can measure distance only or distance and azimuth (ALT-O). See Store Points (GPS Offsets) for more
details.
Configure
This icon will take you to the Configure dialog, also found on the EQUIP tab. From this dialog you can set the number
of readings to average, specify to only store fixed readings, and turn on or off the Hgt/Desc prompt on Save (ALT-C).
Monitor/SkyPlot
This icon will take you to the Monitor/SkyPlot screen for GPS status, coordinates and Lat/Long display (ALT-D).
Store Points (GPS Offsets)
The GPS Offset command allows you to calculate and store points by specifying an offset from a GPS position. Offsets
can either be entered manually or read automatically from a laser. There are three GPS offset methods: Distance/Angle,
Intersection, and Two Point. The current method can be set from the Method tab.
Distance/Angle Offset
In the Distance/Angle method, offsets can be specified manually by choosing the OFFSET tab, or with a laser, by
choosing the LASER tab.
 Manual Offset:
Under the OFFSET tab, offsets are specified by entering azimuth, vertical, and horizontal distance
