Can I use the eTrex Summit 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

No. The GPS satellites are owned by the United States Department of

Reception of GPS satellite signals is free to everyone.
Does the eTrex Summit work anywhere in the world and
in any weather?
Yes.

accurate to within 15 meters. Using differential techniques, the eTrex
Summit can be as accurate as 1-5 meters.
Why can’t I see the display in the daylight?
Adjust the contrast (see page 9).
