ETrex Summit Features Highlight and FAQ

1. Features Highlight

1.1 Elevation Profile

- Real time plot over time and distance (note 1)

- Zoom in/out profile (note 1)

- Review individual elevation points with time and date (note 1)

- Current ascent/descent rate

- Total ascent/descent

- Average ascent/descent rate

- Min/Max ascent/descent rate

- Min/Max elevation

- Local Pressure and 12 hours pressure trend

1.2 Sight 'N Go *

- Sight and locked in a bearing

- Navigate along course by following CDI with off course information *

- Sight and project a waypoint, and navigate to it *

1.3 Track Log

- Automatic elevation and track logging (3000 points/hundreds of miles)

- Save up to 10 tracks (along with elevation profile) with 500 points each

- Note: Clearing track log will also clear elevation profile

1.4 Options/Settings

- Option to show/hide waypoint

- Option to display heading using big numbers

- Option to set different units for distance/speed, elevation, and pressure

- Options to turn on/off GPS and Compass

1.5 Others

- Automatic declination adjustment (all electronic compass need manual adjustment) *

- Automatic map rotation (toward your heading)

- Create new waypoint by projecting from an existing waypoint

- All standard GPS features including marking a waypoint, tracing a path etc

2. Electronic Compass FAQ

- Use outdoors, avoid concrete building, metal doors, power lines etc

- Not tilt-compensated, need to hold level

- Automatic switch over to use GPS when exceeding 10mph

(Because it is difficult to hold or mount compass level when moving fast) *

- Automatic switch back to use Compass when below 10mph for 90 seconds

(Does not switch back immediately because you may be in a stop and go situation)

- Switch-over speed and switch-back time are configurable but rarely needed

- You can Press and hold PAGE to activate Compass immediately

- Compass calibration is an easy 30-seconds process.

- Calibrate the Compass outdoors after a battery change.

3. Barometric Altimeter FAQ

- Automatically use GPS altitude to calibrate altimeter *

- Provide steady relative elevation changes once calibrated

- Most accurate when calibrated manually with known elevation or barometric pressure

- Altimeter is temperature compensated

- Option to turn automatic calibration off

4 Regarding SA Off

- GPS, Compass and Altimeter combo is still very valuable even with SA off

- You still have to walk a few steps before GPS can tell your heading

- Much easier to orient yourself on map and know where to go, even when standing still

- Retracing TracBack path with Compass is much better - you have to try it to believe it *

- GPS altitude still fluctuate too much for elevation profile recording

- Barometric altimeter provides steady and accurate elevation change once calibrated

Note 1

These are features not found in even the most expensive standalone altimeter

* These are features only possible with the integration of GPS, Compass, and Altimeter.
