With the Garmin Foretrex 701 hiking navigation system you determine your position with military precision. The navigation system works with 3 satellite systems: GPS, Glonass and Galileo. The Foretrex 701 has ballistic software for calculating ball trajectories for long range shooting. That is why you use this navigation system not only for adventurous hikes, but also for hunting and military purposes. Thanks to the 3-axis accelerometer, the 3-axis compass and the barometric altimeter, you determine your position when you are moving and at the same time your speed. You simply attach the navigation system around your arm with the wrist strap. Heavy trips and bad weather conditions are no problem, because the Foretrex is shock, temperature and water resistant. You also stay informed about everything because your device receives e-mail, text messages and warnings via your smartphone.
