item features

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.

See where you're headed

Get a better picture of your location with high-resolution photo-realistic views of your route, thanks to direct-to-device downloads of BirdsEye satellite imagery — without an annual subscription. You'll see a true representation of your surroundings to find trails, trailheads and clearings for campsites, to find parks and parking for geocaching, and even to create waypoints based on landmarks.

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.

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.

Hi GPS. I would like to say a big thank you to all at GPS, your advice and expertise has been outstanding, the Garmin GPSMAP66S is performing just as you said it would and some technical questions, I asked Andy were answered immediately. I have been so impressed with the unit, Ive booked onto the two-day training course in April 19 and cant wait. Thanks Again Andy

Posted By: Wesley Mears | Mon 11th November 2019

After owning a Garmin 64, I was doing a gps training coarse and saw the new Garmin 66s, and after using one on the coarse found it simple and easy to access everything I needed, the battery life is excellent, the clarity of the screen is so much better, it is overall faster to process commands, really pleased with my upgrade, would recommend to anyone. Advice given about GPS units and which suits my needs best was a real help, after doing the coarse I felt happy to use my gps with confidence. I made one or two mistakes that where cleared up very quickly via a email to gpstraining which helped get me back in the straight and narrow again. Excellent service
