Zoom Range menu with the 40-80 foot zoom selected. Notice the win- dow on the left zoomed 2X. The zoom range, 40-80 feet, covers a 40-foot water segment. When zoomed in 2X, the zoom window will show 20 feet of the water column with echoes magnified to twice their normal size.

You can select from these zoom ranges: 0-10, 7-14, 10-20, 15-30, 20-40, 30-60, 40-80, 50-100, 75-150, 100-200, 150-300, 200-400, 300-600, 400- 800, 500-1000, 750-1500, 1000-2000 and 1500-3000.

Sensitivity

Sensitivity adjusts the way echoes are displayed on the screen. If you want to see more detail, try increasing the sensitivity, a little at a time. When there is too much clutter on the screen, decrease sensitivity to reduce the clutter and show the strongest fish echoes, if fish are pres- ent. As you change the sensitivity setting, you can see the difference on the chart as it scrolls.
