Map Fix
A Map Fix is used with charts or maps. This system asks for a refer-
ence position in latitude/longitude, taken from a marked location on the
map. It then shows the present position as distance on the map from
that reference point. For example, if it shows a distance of UP 4.00"
and LEFT 0.50", you then measure up four inches and to the left a half-
inch from the reference point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take
your map of the area and determine a reference latitude/longitude.
NOTE:
In order for this system to work, the latitude/longitude lines must
be parallel with the edge of the map. USGS maps are parallel, oth-
ers may not be. This works better with smaller scale maps.
The reference position can be anywhere on the map, but the closer it is to
your location, the smaller the numbers you will be working with. Once
you have decided on a reference position, you can save it as a waypoint.
See the waypoint section for information on saving a waypoint. After sav-
ing the reference position as a waypoint, exit the waypoint screens.
From the Coordinate System menu press ↓ to
SETUP MAP FIX|ENT. The fol-
lowing screens appear with
MAP SCALE highlighted. Press ENT to input the
map's scale. This, typically, is at the bottom of the paper map. It's shown
as a ratio, like 1:24000. After inputting the map scale, press
ENT.
Configure a map fix so the iFINDER can find your position on a
printed chart or topographical map.
