Review on Garmin Fenix 5S Plus Wi-Fi NFC Smart Watch, Silver/Black by Bogomil Stratev ᠌

I didn't study well at school, GPS doesn't work underwater. Even if they don't see GPS on the watch 2-3 cm of water. This is for almost all devices. So when swimming in open water, the strokes should be 50 percent in the air. Otherwise, you won't know how far you've swum. The altimeter is a toy in general. It works . The barometer is so-so. If you are constantly in one place, the barometer works ok. Otherwise, you need it all the time calibrate. I am writing from the phone . There may be typos
