Whether you're hiking, mountain biking, climbing, geocaching, kayaking or working in outdoor environments, navigate your next outdoor adventure with the Garmin GPSMAP 66s.

Get your bearings
In addition to multi-GNSS support, the GPSMAP 66 series provides ABC (altimeter, barometer and compass) sensor capabilities to track your journey. The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer predicts weather changes by showing short-term trends in air pressure. The three-axis electronic compass keeps your bearing whether you're moving or not.

See where you're headed
Get a better picture of your location with high-resolution photo-realistic views, thanks to direct-to-device downloads of BirdsEye satellite imagery — without an annual subscription. Find trails, trailheads and clearings for campsites, find parks and parking for geocaching, and create waypoints based on landmarks.

Stay tuned to conditions
Keep informed of weather conditions by pairing via Bluetooth® to a compatible smartphone. Receive Active Weather updates for real-time forecast information, including predictive maps for temperature, wind, precipitation and clouds. It also provides live weather radar so you’re aware of inclement weather that can affect your outdoor adventures.

Find your cache
GPSMAP 66s and GPSMAP 66st devices make it easier than ever to enjoy geocaching. Set it to automatically update with all the latest caches from Geocaching Live, including cache descriptions, logs and hints. With a Wi-Fi®connection or through Garmin Connect™ on a compatible smartphone, you'll avoid manually entering coordinates or printing out cache details on paper — and each find will automatically upload to your Geocaching.com profile.

Explore with Garmin
Even when you're offline and have no mobile connection, the GPSMAP 66 series pairs with the Garmin Explore mobile app to let you plan, review and sync data, including waypoints, routes and tracks. Plus, you can review completed activities while still in the field, even when you're off the grid. Once you're home again, plan for future trips and review previous activities from the Garmin Explore website.

Utility in adverse environments
Be prepared for the most extreme adventures. The GPSMAP 66 series offers up to 16 hours of battery life in GPS standard mode and 1 week in expedition mode (with two AA batteries) for fewer charges. It provides an LED flashlight and SOS beacon that can be used to signal for help. It's built to military standards for thermal, shock and water performance (MIL-STD-810G), and it's even compatible with night vision goggles.
