These differences are visible only when zoomed out too far to see the detailed charts. Spot Depths: Turns on spot soundings and sets a dangerous depth.
Mapping a Body of Water Using the Garmin Quickdraw Contours Feature Before you can use the Garmin Quickdraw Contours feature, you must have a supported chartplotter with upgraded software, sonar depth, your GPS position, and a memory card with free space. NOTE: This feature is not available on all models. 1 From a chart view, select Menu > Quickdraw Contours > Start Recording. 2 When recording is complete, select Stop Recording. 3 Select Manage > Name, and enter a name for the map.
Navigation with a Chartplotter CAUTION If your vessel has an autopilot system, a dedicated autopilot control display must be installed at each steering helm in order to disable the autopilot system. The Auto Guidance feature is based on electronic chart information. That data does not ensure obstacle and bottom clearance. Carefully compare the course to all visual sightings, and avoid any land, shallow water, or other obstacles that may be in your path.
Marking an SOS Location You can mark an SOS location. When a Garmin VHF radio is connected using NMEA 2000, you can select different SOS types, such as Man Overboard and Piracy. 1 Hold SOS for one second. 2 Select the SOS type. 3 If necessary, select OK to navigate to the man overboard location. If you selected OK, the chartplotter sets a direct course back to the location. If you selected another type of SOS, the call details are sent to the VHF radio. You must send the call using the radio.

The Ultrascroll option quickly scrolls new sonar data, but with a reduced image quality. For most situations, the Fast option provides a good balance between a quickly scrolling image and targets that are less distorted. Sonar Frequencies NOTE: The frequencies available depend on the chartplotter, sounder modules, and transducer being used.
Selecting the Transducer Type Before you can select the transducer type, you must know what kind of transducer you have. This chartplotter is compatible with the Garmin ClearVü transducer as well as a range of accessory transducers including Garmin GT transducers, which are available at www.garmin.com.
