ƒ50 - 50 kHz is particularly useful in deep water, typically greater than 500 ft (150 m) as it produces a good overview of area.

ƒ200 - 200 kHz is particularly good in shallow and medium water, typically less than 500 ft (150 m) or while you're running at speed.

ƒMixed - combines both frequencies on one display screen.

3.Select the new setting. The new setting is shown immediately and stays until you change it again.

16.12Select a split 50/200 kHz screen

You can show the 50 kHz history in one pane and the 200 kHz history in the other. This can be useful if you're operating in shallow to medium water, typically less than 500 ft (150m), and want to compare a wide view of the local area (50 kHz) with a more detailed view of the area under your vessel (200 kHz).

NOTE: You can't use any of the zoom features on this screen.

To show the split 50/200 screen:
