Using Bottom Lock

The scrolling bottom display provides a top-downview, referenced from the surface of the water. Bottom Lock shows a water column of fixed height, referenced from the bottom, that appears flat. It removes bottom detail to provide an image of objects directly above the bottom, and is useful when you are looking for fish that feed close to the bottom.

You can select the Bottom Lock image to be vertically split with the scrolling bottom display, or it can replace the scrolling bottom display. The bottom is shown as a straight line. Notice that some bottom features may extend above this line. The actual depth reading is given in the bottom left hand corner of the Bottom Lock display.

Range intervals on Bottom Lock are measured up from the bottom (rather than down from the surface). Thus, the bottom is shown as zero and the top number indicates the maximum distance above the bottom being displayed. You can adjust the Bottom Lock range.

If the A-Scope or Zoom image is displayed, selecting Bottom Lock automatically switches off A-Scope or Zoom. If split frequency selected, the Bottom Lock image is displayed in both frequency windows. If Target Depth ID is on, the target depth is displayed as distance from the bottom.

To display the Bottom Lock image:

1.Click Bottom Lock.

2.Click Bottom Lock: ON/OFF to toggle the function on.

3.Click Bottom Lock: Full/Split to toggle between a full window bottom lock image or split windows. The bottom lock image is displayed.

If you select split windows, the Fishfinder display is split vertically, with the bot-tom lock image in the left hand window and the scrolling bottom display in the right-hand window. In a split window display, a vertical bar appears referencing the range displayed in the bottom lock window, and varies in height as the bottom lock range changes.

4.To adjust the range, click BL Range Down to select a smaller range, BL Range Up to select a larger range.

5.Click ENTER, CLEAR, or BACK to return to the top- level Functionbar menu.
