The SEAL is
intended for used by mountaineering and orienteering groups that
may require GPS capabil-ity. With the GPS activated, the UTC time,
latitude and longitude will be shown. Compass bearing is provided
by a magnetometer, as GPS will not give reliable bearing data
if not moving. The unit can func-tion without the GPS. Barometric
pressure, which can be converted to altitude, is displayed in
millibars. Because temperature is a component of the pressure
compensation, it too is available, in centigrade format. The SEAL
operates on 2 AAA batteries lasting many hours.
