Introducing snapshots

Taking and storing a snapshot

A snapshot is a picture of the 961/962’s echo sounder screen. You can store up to 10 different snapshots of echo sounder screens for later review. These can be stored on floppy disk (one snapshot per floppy) or zip disk for permanent archiving.

The snapshot feature is not available in the 957/958 or 6000i.

To take a snapshot, press MORE and then SNAPSHOT. The echo sounder screen will be recorded at that instant.

To store the snapshot, you must save the snapshot in one of the ten available storage slots. Choose a slot by pressing the CURSOR PAD up or down to highlight the desired slot, then press SAVE to store the snapshot.
