You can even access professional apps like construction estimators and ArcGIS® to extend some office functions to the field. The rugged and durable Monterra has the power and flexibility to go anywhere.3D MapMergeMonterra is the ultimate mapping tool with custom 3-D mapping, which lets you combine 2 maps - like TOPO, basemap or BirdsEye Satellite Imagery - then view the new unique map in 3-D complete with visible “texture,” such as hills, valleys, lakes and forests. For example, combine BirdsEye with TOPO U.S. 24K or a GIS-based water table map with your shaded relief basemap. Then zoom in, pan out and rotate the 3-D map using multi-touch.Double Your PowerMonterra features a state-of-the-art dual battery system. You’ll have the option of using the rechargeable lithium-ion pack (included) or traditional AA batteries — lithium-ion pack charges when device is connected to external power.Quality PhotosMonterra includes a built-in 8 megapixel autofocus digital camera that takes vivid, geo-tagged photos for easy return navigation plus a 1080p HD video camera with LED flash/torch. Then download easily to your computer or for sharing through Garmin Adventures. Monterra has plenty of internal memory plus a microSD™ card slot for up to 64 additional GB of memory.Easy-to-see DisplayMonterra’s reflective display technology uses external light, like sunlight, in combination with the unit’s LED backlight to increase brightness and view-ability. Plus, you conserve power by not having to turn on the backlight.Get Your BearingsMonterra has a built-in 3-axis electronic compass with accelerometer and gyro, which shows where you're heading even when you’re standing still (or not holding it level). Once calibrated, its barometric altimeter tracks changes in pressure to pinpoint your precise altitude, and you even can use it to plot barometric pressure over time, which can help you keep an eye on changing weather conditions. A built-in UV sensor lets you know your exposure level to sunlight so you can avoid sun damage, especially at higher elevations (5 percent increase in intensity every 1000 ft of altitude) and on bright or reflective surfaces (snow, water, etc). And with its high-sensitivity, WAAS- and GLONASS-enabled GPS receiver, Monterra locates your position with more precision and maintains its GPS location even in heavy cover and deep canyons.Share WirelesslyWith Wi-Fi, ANT+™, Bluetooth® and NFC, Monterra lets you share your data, maps, waypoints, tracks, routes and geocaches up to 50 times faster with other wireless compatible devices. Plus, you can share large files like photos and data from field work through BaseCamp™ or by downloading it directly to your computer.Add MapsAdding other Garmin maps to Monterra is easy.
