to mark is inaccessible (i.e. like a power pole behind a fence or
an island in a lake), when the GPS signal at a desired point is
unavailable (it may be blocked), or when gathering points from a
vehicle without having to get out of the vehicle.
To use the Mark Point Offset function, complete the following steps:
1. Fill in the Distance from where your current location is to the
point you are wanting to save.
2. Fill in the Direction in degrees that the new point is located.
3. Fill in the Slope from where you are located to the new point.
Use a clinometer to measure the slope.
4. Check the Offset On check box, after these fields are filled in,
if you want the offset calculations activated before closing the
waypoint.
Now, whenever you select the saved offset point, if the Offset On
check box is checked, an indicator appears in the Waypoint screen
while viewing the point information.
If you want to view the unaltered point information, tap on the
Edit button in the Waypoint screen.
Offset values are activated automatically when saving/closing the
waypoint by tapping on the OK button. The Cancel button does
not save any of settings or impose the new offsets.
Average
The Average button is used to average GPS fixes that pass the
mask settings. When you press the Average button, the bar graph
above starts to fill, showing a ratio of points that have been
included in the average so far.
The status/quality of GPS averaging is displayed in the box to the
left. If a reading is masked, the reason for being excluded from
the average is displayed in the box to the left.
The running and final averaged information is located to the left
of the Average button. While a waypoint is being averaged, the
average button displays Averaging.
If the Store Wpt button is pressed during the averaging process,
the final average is not stored until all the points specified to
compute the average have been included. You will notice that the
Store Wpt button shows waiting while it is averaging. Similarly,
final data cannot be exported until averaging is complete.
