Radar
The Garmin MFD can be used for the radar
display as well. At the lower helm we
generally use the smaller screen for the radar.
If the radar screen is not displayed, press the
‘Home' menu at the bottom of the screen and
then either Combos or Radar at the right
hand side of the display then select the view
that you want to use. When the radar is ready
to transmit:
Select Menu>Transmit radar
Or touch the Transmit icon in the
upper left corner.
The radar can be overlayed onto a chart so
that radar targets will be displayed in
reference to charted features.
Select Menu > layers > radar then
choose the desired view.
Note:
Your charter’s insurance does not permit operation of the vessel in restricted visibility
such as fog. You should learn to use the radar in weather with good visibility to familiarize
yourself with operations, and with a second crew member at the helm to maintain a proper
lookout.

Using a combo screen on the smaller MFD you can see depth information alongside a chart or
radar. The display can be calibrated for an off set to depth under the keel however, it is always
safer to assume that the depth of the display is from the surface of the water, and that you
need to subtract the draft of the boat (4.5 feet) for the depth of water under the keel.
