Depth Alarm. The 450TX contains an audible
alarm to warn you of shallow water depths. The
alarm is adjustable to depths of .6m (2') to 30m
(99'). When the alarm is enabled, an audible alarm
sounds if the water beneath the boat is equal to or
less than the selected alarm depth. The alarm
sounds continuously for about five seconds, and
then intermittently to remind you that you are still
in shallow water.
Additionally, the 450TX can
anticipate quickly changing terrain and sound
the Depth Alarm before the bottom depth
actually reaches the preset alarm depth.
