How to Balance Echo Strength
A school of fish at a depth deeper than a school of equal strength in shallow water ap-

wave. To display the schools of fish in the same colors, use the TVG. The TVG auto-

1. Tap the cogwheel icon at the bottom-left of the fish finder screen. The quick set-

1. Tap [Home] => [Settings] => [Fish Finder] => [Zero Line].
2. Tap the toggle box at [Zero Line Rejection] to show [ON].
