ABSTRACT:
A small-sized electronic device with depth gauge includes a pressure sensor for measuring a present water pressure and outputting a pressure value. A memory stores the pressure data. A dive time measuring circuit measures a dive time interval. A mean depth calculator receives the pressure data and dive time interval and in response thereto outputs a mean depth value which is displayed on the device.
