Decide what you need a
tactical watch with GPS for. For example, if you need it for sports training, you may need GPS to track your path and distance. If for tactical missions or survival, features such as night vision, built-in compass and durability may be important. I ordered a tactical watch with gps from the Battle Steel store. Think about what features are important to you. Some common features of such a watch may include GPS navigation, altimeter, barometer, compass, heart rate sensors, exercise functions, night vision and so on.
