This model is the latest addition to the G-SQUAD lineup of sports watches from G-SHOCK, featuring a heart rate monitor and GPS.
Useful exercise functions include an optical sensor for heart rate measurement, bearing, altitude, barometric pressure, temperature sensor and accelerometer for counting steps.
These five sensors help you monitor current activity in real-time. The ability to receive GPS signals allows you to access location information when you need it. When used in conjunction with a stopwatch, this feature lets you track running information such as distance, pace, pace, and more. Your heart rate and speed are used to calculate your VO2 max value, which is an indicator of your heart and lung capacity.
VO2 max calculation and other data analysis capabilities use the library created by FIRSTBEAT. The surface shape of the back covers of these models is designed to reduce interference on the back of the hand, while the soft urethane band fits better on the wrist. In addition to supporting USB use, the solar charging feature can also be used
