Designed with a large LCD screen, the PRG-40 displays direction, altitude / barometric pressure and temperature readouts. The compass, barometric pressure, and altitude functions of the watch are assigned to separate buttons so data is always at your fingertips whenever you need it. The digital compass can be used to take real-time readings as you move. These features, and more, make this model a valuable tool that can provide that extra margin of assurance that your outdoor adventures will always be safe and successful.
