Sonar Views

The sonar views available vary depending on the type of transducer and optional sounder module connected to the chartplotter. For example, you can view the Split Frequency view only if you have a dual-frequency transducer connected.

There are four basic styles of sonar views available: a full- screen view, a split-screen view that combines two or more views, a split-zoom view, and a split-frequency view that displays two different frequencies. You can customize the settings for each view in the screen. For example, if you are viewing the split-frequency view, you can adjust the gain for each of the frequencies separately.

If you do not see an arrangement of sonar views to suit your needs, you can create a custom screen (Customizing the Layout of a Page).

Full-Screen Sonar View

There are several full-screen views available, depending on the equipment connected. The full-screen sonar views show a large image of the sonar readings from a transducer. The range scale along the right side of the screen shows the depth of detected objects as the screen scrolls from the right to the left.

DownVü Sonar View

NOTE: Not all models support DownVü sonar technology and transducers.

NOTE: To receive DownVü scanning sonar, you need a compatible chartplotter or fishfinder and a compatible transducer.

DownVü high-frequency sonar provides a clearer picture below the boat, providing a more detailed representation of structures the boat is passing over.

Traditional transducers emit a conical beam. The DownVü scanning sonar technology emits a narrow beam, similar to the shape of the beam in a copying machine. This beam provides a clearer, picture-like image of what is beneath the boat.

SideVü Sonar View

NOTE: Not all models support SideVü sonar and scanning transducers.

NOTE: To receive SideVü scanning sonar, you need a compatible chartplotter, a compatible sounder module, and a compatible transducer.

SideVü scanning sonar technology shows you a picture of what lies to the sides of the boat. You can use this as a search tool to find structures and fish.

SideVü/DownVü Scanning Technology

Instead of a more common conical beam, the SideVü/DownVü transducer uses a flat beam to scan the water and ground to the sides of your boat.

Split-Zoom Sonar View

The split-zoom sonar view shows a full-view graph of sonar readings, and a magnified portion of that graph, on the same screen.

Split-Frequency Sonar View

In the split-frequency sonar view, one side of the screen shows a full-view graph of high frequency sonar data, and the other side of the screen shows a full-view graph of lower frequency sonar data.

NOTE: The split-frequency sonar view requires the use of a dual-frequency transducer.
