Terrain Contours - Maps with terrain contours are also referred to as topographical maps. They show striations representing the topography of the land. Garmin maps are typically 100K (1:100,000 scale) or 24K (1:24,000 scale) for contour intervals.

GNSS is a generic term referring to all satellite navigation systems. Most Garmin receivers track GPS, GLONASS and Galileo, and some regional variations even track BeiDou and QZSS.

The company specializes in GPS technology for automotive, aviation, marine, outdoor, and sport activities. Due to their development in wearable technology, they have also been competing with activity tracker and smartwatch consumer developers such as Fitbit and Apple.

With distance measurements from a few more satellites, the receiver can determine a user's position and display it electronically to measure your running route, map a golf course, find a way home or adventure anywhere.

Garmin GPS receivers are typically accurate to within 10 meters. Accuracy is even better on the water because there are no obstructions to interfere with the signal. A Garmin GPS receiver's accuracy is improved when using the Wide Area Augmentation System (WAAS).
