Navigate your next outdoor adventure with the GPSMAP 66 series. Whether you’re hiking, mountain biking, climbing, geocaching, kayaking or working in outdoor environments, you can explore more with this iconic rugged handheld with a 3? colour display. It offers a new quality of positioning with Quad-Helix antenna performance and multi-satellite support as well as wireless connectivity for Active Weather, direct downloads and Garmin Explore compatibility.

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 can be used to predict weather changes by showing short-term trends in air pressure. The three-axis electronic compass keeps your bearing whether you’re moving or not.

Stay tuned to conditions

You’ll always stay informed of weather conditions when you pair your GPSMAP 66 series device 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 your geocaching experience. 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 profile.

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.
