How to Use Fish Finder Sonar
- 1). Install the transmitter. You'll usually have a choice between mounting the transmitter beneath the boat, to a trolling motor or atop the interior hull and letting it drop into the water.
- 2). Set the fish finding sonar's sensitivity while watching the display. When the sensitivity is too high, there will be static-like patterns on the display. If the sensitivity is too low, not even the bottom of the body of the water will appear on screen.
- 3). Determine the depth of the body of water. This will be a numeric value on the fish finder sonar system's display. This is important in helping you to determine how much fishing line to feed out from your pole.
- 4). Get accustomed to the display's representation of the body of water. The bottom will appear as a jagged, solid line near the bottom of your display. The surface of the water appears as a jumbled static-filled horizontal line at the top of your fish finder sonar system's display.
- 5). Learn to identify patterns on your display that are brush piles if you're fishing on a lake. Brush piles appear as blobs resting on the lake bottom. Fish such as bass hide out in brush piles, so consider fishing near these echoes.
- 6). Learn how to identify fish on your fish finder sonar system display with the fish symbols turned off. With the symbols turned off, fish appear as short curved lines above the bottom of the body of water. Adjust the fish finder sonar's noise filter if there are lines in your display that look like random static.
- 7). Remember what the fish finder sonar display was indicating when you catch a fish. This will help you to learn how to use your system to catch more fish later if you keep in mind what to look for.
