Dakota 20 has a built-in 3-axis electronic compass, which shows your heading even when you’re standing still or not holding the device level. Its barometric altimeter tracks changes in pressure to pinpoint your precise altitude, and you can even use it to plot barometric pressure over time, which can help you keep an eye on changing weather conditions. And with its high-sensitivity, WAAS-enabled GPS receiver with HotFix™ satellite prediction, Dakota 20 locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons.
