1. Depress the 

 key to turn on the unit. 

2. Head for your fishing grounds. Your unit automatically displays digi-

tal depth and surface water temperature in the corner of the screen. 
The auto settings will track the bottom, displaying it in the lower por-

tion of the screen. The full sonar chart will scroll from right to left, 

showing you what's under the boat as you cruise across the water. 
3. As you're watching the sonar returns, you can change the display by: 
      Zoom in to enlarge the chart for more detail: press 

. 

      Zoom out to return to full chart mode: press 

. 

4. If necessary, adjust sensitivity to improve chart readability. Press 

|

 and the Sensitivity Menu will appear on the left of your 

screen. Use 

↑ and ↓ to change the setting. 

Boosting sensitivity will show more information on your screen, which 

may cause clutter. Reducing sensitivity will filter out some informa-

tion, but could omit important images. We recommend adjusting sensi-

tivity until the background is lightly "peppered" —  that is, scattered 

dots appear, but individual objects (like fish arches or bottom struc-

ture) can be easily picked out of the background. 
5. Watch the display for the appearance of fish arches. When you see 

arches, you've found fish! Stop the boat and get your lure or bait into 

the water at the depth indicated on the sonar chart. 
6. Gauge the fish depth by visually comparing the fish arches with the 

depth scale on the right side of the screen, or get a more accurate 
measure with the Depth Cursor. Press 

|

↓ to 

|

. 

Press 

↓ (or ↑) to align the cursor line with the fish arch. The exact 

depth appears in a box at the right end of the cursor line. To clear the 

cursor, press 

. 

7. If you are drifting at a very low speed or anchored, you are not mov-

ing fast enough for a fish to return the tell-tale fish arch signal. As you 

drift over a fish, or as a fish swims through the transducer's signal 

cone, the fish echo will appear as a straight line suspended between the 

surface and the bottom. 
8. To turn off the unit, press and hold 

 key for three seconds.
