• CDI Steer To allows you select a steer-to-center or steer-to-D-Bar orientation for

graphic steering guidance. The steer-to-center selection displays your position as the

vertical line on the scale, and your desired track as the center of the scale. The steer

to D-Bar option displays your position as the center of the scale, with the desired

track as the vertical line. The default setting is steer to center.

• Map Datum provides a list of the available map datums for use with the GPSMAP

system. For a list of the available GPSMAP datums, see Appendix D. The default set-

ting is WGS 84.

• Velocity Filter allows you to select the GPSMAP’s response time to changes in

track or ground speed. Three settings are available: automatic, on, or off. The ‘auto’

(default) setting will monitor the changes in your current track and speed and

adjust the receiver’s response time automatically. The ‘on’ setting allows you to

manually enter a response time up to 240 seconds. Selecting a higher setting may be

desirable in slow-speed applications with frequent changes in track.

To enter a user defined velocity filter value:

1. Highlight the ‘Velocity’ field and press

. Select the ‘On’ option and

press

2. Highlight the time value field.

3. Press

4. Enter a value in seconds (up to 240) and press

to confirm.

A. CAUTION! Using the incorrect map datum can

seriously effect the accuracy of your GPS receiver.

The GPS datum should always match the datum of

the local chart you are using. If no datum informa-

tion is indicated on the charts you are using, contact

the chart manufacturer.

B. Keeping the velocity filter on the ‘Auto’ setting will

allow the GPSMAP 130 to automatically monitor

and adjust the response time for track and speed

calculations.
