2. Bottom Zoom (200 KHz or 50 kHz)
Bottom Zoom magnifies the sounder display from the bottom up toward the surface for a preselected
distance. The bottom contours are displayed and additional contour lines are added at intervals above
the bottom to aid in determining distances of echoes from the bottom. Use the Sounder Menu to set
the Bottom Zoom Range. Choices are 8.2ft, 16.4ft, 32.8ft, 65.6ft. Default setting is 8.2ft
Bottom Zoom mode is not effective in less than 10ft of water. Bottom zoom mode is selectable for
single frequency or dual frequencies.

image. The bottom appears as a straight line with the Fish images magnified above the bottom.
Bottom Lock mode is very handy for picking out fish swimming close to the bottom when sea
conditions are choppy. A scale appears on the right side of the screen for estimating distances of fish
echoes from the bottom. Use the Fish finder Manu to set the Bottom Lock range, choices are 8.2ft,
16.4ft, 32.8ft, 65.6ft . Default setting is 8.2ft.
