The digits show the water depth below the boat. In this exam-
ple, the depth is displayed in Metres.
As a default, the Combi will display the depth below the trans-
ducer. An offset can be entered so that the display shows
either the depth below the keel or the waterline depth. Refer
to Section 3.3 for more details.
The IS12 Combi features an audible alarm function that can be
set to alert if the water depth falls below or above a specified
value. The shallow alarm will sound if the water depth falls
below a specified amount, to warn if the boat is about to run
aground and the deep alarm will sound if the water depth
goes above a specified amount.
This function can also be used as a navigation tool when navi-
gating using depth contours - by setting the shallow and depth
alarms below and above the required contour depth, the alarm
will sound if the boat strays off the contour.
