Zoom
The zoom feature enlarges all images on the screen by doubling the size of the echoes (a 2X zoom). For example, if the current auto depth range is 0 to 60 feet, Zoom will show an enlarged view of the water column from 30 feet to 60 feet, always keeping the bottom in view.
To zoom in the display, repeatedly press MENU until the ZOOM menu appears. Press ↓ to select ON, then press PWR to clear the menu.
Zoom feature turned off (left). Zoom turned on (right).
You can tell when the display is in Zoom mode when the top of the depth scale on the left of the screen no longer shows zero. For example, if the current range is 0 to 80 feet with zoom off, switching to zoom would en- large the water column from 40 feet to 80 feet. The number 40 would ap- pear at the top of the depth range scale.
To turn off the zoom feature, repeatedly press MENU until the ZOOM menu appears. Press ↑ to select OFF, then press PWR to clear the menu. The top of the depth range scale returns to zero.
NOTE:
Using the Zoom command while in auto Zoom mode will always enlarge the echoes near the bottom, because auto Range always keeps the bottom displayed in the lower portion of the screen.
When you choose to use the zoom feature while the unit is in manual Depth Range mode, you can select one of 17
To do this, make sure Depth Range is set to manual mode. Next, re- peatedly press MENU until the ZOOM menu appears. Press ↓ to select ON, then press MENU UP to display the ZOOM RANGE menu.
Use the arrow keys to select a desired zoom size. When you are finished, press PWR to clear the menu from the display.
