Has some pros: New version of Pro Tracks that includes Bluetooth functionality. Excellent readability achieved with the use of large hands and a display that is not inverted. Excellent brightness of the illumination, and the arrows have a luminous coating. A pedometer has been included, which was not the case with earlier versions. Because of the Bluetooth correction, the accuracy is atomic. Very good strap. Yes, everything about the way the device was put together is very impressive. Going to a certain destination, such as going back to a car that was parked in an unusual location or driving to a mushroom meadow in the woods, serves an interesting purpose. However, keep in mind that in order for this to operate, you will need a smartphone. Its cons: The lack of a solar battery is something that a lot of people see as a drawback, but in my opinion, this is not the case at all! After a few years, by simply turning four screws, you will be able to easily replace it (CR 2025), and at the same time, you will also be able to seal it.
