Important Tip:
While you are experimenting and learning, it's possible to scramble the settings so the sonar picture disappears from your screen. If that happens, remember it's easy to switch back to full automatic operation by simply restoring the factory settings. Here's how:
To Restore Factory Settings
1.Press MENUMENU↓ to SYSTEM SETUPENT↓ to RESET

2.The unit asks if you want to reset all the options. Press ← to YESENT. All options are reset, and the unit reverts back to the Map Page at the
Fish Symbols vs. Full Sonar Chart
You may have noticed in the quick reference we used fish arches in full sonar chart mode for our example and not the popular Fish I.D. fish symbol feature. Here's why.
Fish I.D. is an easier way for a sonar novice to recognize a fish signal return. However, locating a fish via symbol has some limitations.
Your sonar unit's microprocessor is remarkably powerful, but can be fooled. Some of the echoes displayed as fish could be tree limbs or turtles! To see what's under your boat in maximum detail, we recommend you turn off Fish I.D. and begin learning to interpret fish arches.
Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen. Then, you can turn on Fish I.D. and the audible fish alarm. When that lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, in one case, fisherman in San Francisco Bay saw clouds of clutter in the water but no fish arches. When a downrigger was pulled up, it brought up several small jellyfish. The fisherman switched their Eagle sonar to Fish I.D., which screened out the schools of jellyfish and clearly showed the game fish as fish symbols.
