By using Bluetooth communication with the dedicated PRO TREK Connected application, you can use your smartphone to simplify the various settings and automatically adjust the time. Corrections can be made. Improved usability in outdoor activities such as climbing, hiking, camping, etc. A quad sensor with a built-in acceleration sensor for measuring steps is realized in addition to a small sensor that can measure direction, altitude/air pressure, and temperature. The application records the calorie consumption with the altitude measurement information and step count measurement information, taking into account the elevation factor. The app automatically records the altitude acquired by the watch and the route acquired by the GPS of the smartphone, and the altitude points acquired by manual operation are plotted on the route log. In addition, the current location is recorded in the app with the touch of a button on the watch, and after moving, the direction to the recorded location is displayed by the second hand, and the distance to the recorded location is displayed on the LCD, which makes it easy to understand the relationship between your current location and the recorded location.
