Pic. Advance

Allows the sonar picture to advance faster by drawing more than one column of data on the screen for each column of sonar data received. This is especially helpful when you are using the sonar in deep water, because the sonar signal takes longer to travel to the water bottom and back to the transducer.

The 1/1 setting draws one column of information on the screen per sonar return. The 2/1 setting draws two columns of information on the screen per sonar return, and so on for the 4/1 and 8/1 settings.

Echo Stretch

Adjusts the size of the echoes on the screen to make it easier to see separate returns on the screen.

When targets are difficult to see , echo stretch makes the target returns more pronounced and easier to see on the screen. If the echo stretch value is too high, the targets blend together. If the value is too low , the targets are small and more difficult to see.

You can use echo stretch and filter width together to obtain the preferable resolution and noise reduction. With echo stretch and filter width set to low, the display has the highest resolution, but is the most susceptible to noise. With echo stretch set to high and filter width set to low, the display has a lower resolution, but has wider targets. With echo stretch and filter width set to high, the display has the lowest resolution, but is the least susceptible to noise. It is not recommended to set echo stretch to low and filter width to high.

Overlay Data
