No matter what boat or sonar, you can improve your catch by correctly interpreting and understanding your fishfinder. Fishfinders can really increase your catch if you know how to set them up properly and interpret them correctly. In order to properly interpret sonar, you must know how a fishfinder works. This program teaches anglers how to interpret the sonar returns shown on their fishfinder's display in a step-by-step, easy to understand manner. Most anglers rely strictly on fish identification features on their fishfinder, which can show many objects as fish that are not actually fish. Any submerged object between the surface and the bottom capable of returning sound, such as a tree limb, may be shown as fish on the screen. Another common problem angler's face is fully understanding the cone angle and coverage of their transducer. The gain adjustment can vary from what is shown and not shown on the display. While automatic adjustments in range and gain are usually adequate for running a boat, they are usually inadequate for finding fish. It is therefore important to understand frequencies and how to manually adjust settings to get the most from your fishfinder.
