10 -- Practical Navigation Example

10.1 -- Fishing Trip to Ice Lake

You are planning a trip to fish in Ice Lake. You have a topographic map of the area, and

will drive to the trailhead. Your plan is to store the vehicle as a *HOME* position and

navigate to the lake using your new Multi-Navigator. After fishing you would like to travel

back to the vehicle using the StraightHome feature.

10.1-1 Position of Ice Lake

Before you can use your Multi-Navigator to find Ice Lake you need to determine the

lake’s location. Since your map uses the UTM coordinate system, determine the position

of Ice Lake using the UTM tick marks on the map.

1. Connect like UTM markings with lines across the map. (Fig. 30)

2. Now, find the zone and map datum, in the map’s margin (zone 11 & NAD-27).

! Since the map is North of the Equator, label the zone -- N 11.

3. Next measuring the Eastings and Northings of your location.

! Start in the lower left-hand corner of the box surrounding the your location.

A. Measure in an Easterly direction until directly under your location.

! Approximately 600 meters to the right of 599000 mE.

! Therefore, the Easting coordinate is E599600.

B. Now, measure in a northerly direction.

! Your location is approximately 750 meters North of 4790000 mN.

! The Northing value is N4790750.

The position of Ice Lake is:

Zone - N 11

Easting - E599600

Northing - N4790750

Map Datum - NAD-27 (US)

Since, you do not need the GPS receiver on while planning your trip turn it off to save

battery life by pressing SET and then YES while in the POSITION function.

If you have not yet selected UTM / UPS as a Position Format follow the instruction below.

1. Press SET in the Position function to get to SETTINGS, and scroll to the POSITION

FORMAT setting using UP or DOWN.

2. Press SET and scroll until UTM / UPS is displayed and press SET.

3. Press YES again to select AUTO ZONE.

4. Now scroll through the map datums until your reach NAD-27 US and press SET.

All positions will now be shown in UTM / UPS format as on your map.
