Garmin GPSMAP 64st, TOPO U.S. 100K with High-Sensitivity GPS and GLONASS Receiver

Garmin GPSMAP 64st with TOPO U.S. 100K mapping is the proven entry point for backcountry navigators who want genuine topographic maps without the learning curve of a blank-screen GPS that requires separate map purchases and loading. The preloaded 100K maps show the terrain features that matter for hiking and hunting: drainages, ridgelines, elevation contours, and trailhead access — available from the moment you turn the unit on.

TOPO U.S. 100K Maps and Dual-Constellation Reception

The 100K scale provides clarity for route planning without visual clutter — you can read ridgelines and drainages at a useful zoom level without scrolling through the detail that obscures the big picture at higher-resolution map scales. For larger-scale trail planning and hunting area scouting, 100K resolution is the right working scale. The dual-constellation receiver combines GPS and GLONASS satellites for faster acquisition and more reliable position holds in dense tree cover and canyon terrain where single-constellation GPS loses signal reliability.

• TOPO U.S. 100K maps preloaded — ridgelines, drainages, and trailheads ready on arrival
• Dual GPS and GLONASS — reliable lock in canyon and heavy tree cover terrain
• 2.6-inch sunlight-readable color display — visible in direct light
• Waypoints, tracks, and routes — complete navigation workflow in the field
• AA battery power — week-plus field life on a single pair of cells

The GPSMAP 64st is the right choice for hikers, hunters, and backcountry travelers who want complete topographic map coverage across the United States in a proven button-driven handheld that runs on standard AA batteries without requiring charging infrastructure in remote locations.
