APPENDIX B
Specifications
Specifications subject to change without notice.
* With optional GARMIN Differential Beacon Receiver Input (such as GARMIN GBR 21 or GBR 23).
**
Subject to accuracy degradation to 100m 2DRMS under the U.S. DoD-imposed Selective Availability Program.
† The temperature rating for the GPS III+ may exceed the usable range of some batteries. Alkaline batteries can rupture at high temperatures.
‡ Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium batteries when operating the GPS III+ in
below freezing conditions. Extensive use of screen backlighting will significantly reduce battery life.
