How to change the picture advance speed

The Picture Advance setting sets how quickly vertical scan lines move across the dis-
play. When viewing a seabed with sharp rises and falls, such as a reef-bed or sub-
merged wreck, a fast advance speed helps to "smooth" out the seabed for easier
viewing. On the other hand, when viewing a smooth seabed with little to no undula-
tions, a slow advance speed helps to identify rises and falls.
You can change the picture advance speed with one of the following methods.
From the menu
1. Open the Home screen, then tap [Settings][Multi Beam Sonar].
2. Tap [Multi-Sounder].
3. Tap [Picture Advance].
4. Select an advance speed to suit your requirements.
