No Limits

No more picking, choosing and planning, just download them all. The GPSMAP 66 supports virtually unlimited geocaching, indexing up to 4 million geocaches (GPX and/or GGZ format). Access individual geocaches, PQ's and Lists directly from Geocaching.com. Load GPX/GGZ files from your favorite geocaching database software or hosting website. All paperless features are available for every geocache. Read complete descriptions, hints and logs. Filter caches by size, terrain, difficulty and type. Enable/Disable individual GPX/GGZ files! Connect to chirp enabled caches. Record and publish your logs while in the field. The GPSMAP 66 provides best in class geocaching capability.

Tip: Add benchmarks to your Garmin GPSr!

New Geocaching features are available with the version 4.70 firmware update:

• New: Geocache child waypoints are now automatically downloaded via GCLive!
• New: Enable Proximity Alarms so you never have to miss another unfound geocache again!

GPX vs GGZ

Use one or the other, or use them both. The GPSMAP 66 provides full geocaching functionality regardless of format. Using GGZ files substantially improves the GPSMAP 66 searching and indexing speeds. GGZ files consist of a compressed geocache GPX archive that includes an XML index containing only the information essential to searching and indexing functions. When a specific geocache is selected, additional information is then retrieved from the corresponding GPX file as required. Removing unnecessary information from the sorting process translates into a more efficient and enjoyable geocaching experience.
