Virtual - Electronic Altimeter / Barometer
The altimeter displays the current altitude in feet or meters, the difference between current and reference altitude, and graphic altitude history for the past 12 hours. Retains memory of maximum / minimum height reached and of the cumulative vertical ascent/ descent. User-programmable alarm. The barometer displays current barometric pressure in mb/hPa or in. Hg and graphical history for the past 12 hours. A storm alarm alerts user when a storm condition is approaching. °C or °F selectable. Clock features a user-selectable 12- or 24-hour format, month, date, alarm and a stopwatch on an easy-to-read LCD display. Includes wall mount and lanyard.
