Casio Protrek Triple Sensor Watch PRG90 PRG90-3VDR

Altitude Differential Pointer : A pointer on the display shows the difference between your current altitude and the last altitude measurement. This information helps to determine your pace while mountain climbing or hiking.

Barometric Pressure Differential Pointer : This pointer shows the relative change in barometric pressure between the current reading and the last reading.This means you always have the most up-to-the-minute information at your fingertips, which gives you a very good idea of upcoming weather conditions.
