The eTrex is a six ounce, 12 channel, hand heldGPS receiver. It has a built-in GPS antenna and only fiveuser-buttons. All buttons are located on either side ofthe unit, allowing for simple, one-handed operation thatwon’t obstruct your view of the display. It runs for 22

hours on two AA alkaline batteries in battery save mode.

In addition to determining your location, the eTrexwill create, name and save a location (as an electronicwaypoint) in its memory, allowing you to navigate back tthis point any time you want. And once you start movingyour GPS provides other data, like speed, direction ofmovement, time and distance to destination, and more.

From these basic features, your GARMIN GPS canprovide one more critical benefit; peace of mind, because,

with GPS you’ll know where you are, where you’ve beenand where you’re going. And since you’ll always know thway back home, you can concentrate on what you set outo do and enjoy the great outdoors.

Other features include:

Waypoints: 500 with name and graphic symbol

satellite signals, and the satellite tracking status.

FNOTE: When you use the eTrex for the firsttime, it will take up to five minutes to find you

The eTrex allows you to navigate using one of threemethods:

• GOTO

• Route• TracBack

The GOTO method of navigation was brieflydiscussed on page 16. This section discusses the routemethod. The third method, TracBack, is discussed on

page 28. In the eTrex, a route is at least two waypointshat describe the path you are going to travel. The routefeature is very convenient because it allows the eTrexto guide you from the first waypoint in the route, toeach successive waypoint until you reach your final

destination. The route feature and the GOTO feature arecomparable in that they both guide you to destinationwaypoints.

However, the route feature is more powerful becauseit is more automatic. When you reach one waypoint, theeTrex automatically guides you to the next waypoint onthe route without needing to touch any button. When yo

Interface PageThe Interface Page allows you to connect and use

devices such as computers and differential GPS (DGPS)beacon receivers to the eTrex.

Input/Output SettingsThe ‘Interface’ Settings Page allows you to use your

eTrex with external NMEA devices, DGPS beacon receiv-ers, a personal computer, etc. You can choose from sevendifferent input/output serial data formats, or none at all.

Below is a description of each format:

• GARMIN - the proprietary format used to exchangewaypoint, route, and track data with a PC.

• GARMIN DGPS - allows DGPS input using a GARMIN

beacon receiver and a standard RTCM SC-104 formatand DGPS tuning.

• NMEA OUT - supports the output of standard NMEA0183 version 2.0 data.

• TEXT OUT - allows simple ASCII text output oflocation and velocity information, without any inputcapabilities.

• RTCM IN - allows DGPS input using a standard RTCM

GPS - the Global Positioning System - is anavigation revolution. It’s a technology that pinpoints auser’s location anywhere in the world, 24 hours a day,regardless of the weather.

Designed by the United States’ Department of Defensfor use by the military, the GPS System was madeavailable to civilians for use in aviation, marine surveyingand general outdoor/recreation markets. Today, millionsof people utilize the accuracy and convenience of thisamazing technology to hunt, fish, hike, fly, cruise and saGPS consists of a constellation of 24 satellites orbitingsome 12,000 miles above the earth.

These satellites transmit signals containing time and

orbital data to calculate satellite position and almanacdata. Meanwhile, receivers used on the ground, sea andair search the sky for the satellites. The GPS unit needsto acquire good signals from at least three satellites todetermine a position on the surface of the earth. A fourthsignal is required to get three-dimensional positioningwhich determines elevation or altitude.

Interface formats are selected from the SETUP Page.The input/output lines on your eTrex are RS-232 compatible, allowing easy interface to a wide range of externaldevices, including PC’s, differential beacon receivers,marine autopilots and/or a second GPS receiver.

The NMEA 0183 version 2.0 interface format issupported by the eTrex and enables the unit to drive upto three NMEA devices.

NMEA 0183 Version 2.0 Approved Sentences:

GPGGA, GPGLL, GPGSA, GPGSV, GPRMB, GPRMC,GPRTE, GPWPL, GPBOD

GARMIN Proprietary Sentences:

PGRME (estimated error), PGRMM (map datum),PGRMZ (altitude), PSLIB (beacon receiver control)

DGPS (Differential GPS) corrections are accepted inRTCM SC-104 version 2.0 format through the ‘Data In’line. The GARMIN GBR 21 is the recommended beaconreceiver for use with the eTrex. Other beacon receivers

with the correct RTCM format may be used, but may notcorrectly display status or allow tuning control from theGPS unit.

Can I use the eTrex indoors?No. The DEMO mode is available, but we suggest that only dealers

use it.

Do I need to subscribe to a service to use the eTrex?No. The GPS satellites are owned by the United States Departmenof Defense (DoD) and have been funded by U.S. taxpayers’ dollarsReception of GPS satellite signals is free to everyone.

Does the eTrex work anywhere in the world and in anyweather?

Yes.How accurate is a GARMIN GPS?The eTrex is accurate to within 15 meters without the DoD-imposeSelective Availability (S/A). Using differential techniques, the eTrexcan be as accurate as 1-5 meters. The eTrex is accurate to within

100 meters under S/A.Another factor that will effect the accuracy of the GPS receiver isthe geometry of the satellites in view of the GPS receiver. A poorgeometry situation can provide less accurate position readings, anthis especially applies to GPS altitude measurements. The altitude

reading on the GPS unit can vary by +/- 450 ft. depending on thelevel of degradation being imposed under S/A. It is not uncommonto see the altitude continuously drift up and down when S/A isbeing imposed.
