Fish Finder Manuals

Fish Finder Manuals are designed so that you can find the information you need quickly and easily, so that you spend more time boating and fishing than reading.

How does SONAR work?

SONAR(SOund NAvigation RAnging)
Sound moves thru water at about 4920 feet/second (almost a mile).

Your fish finder measures the amount of time it takes for the sound pulse it sends out to travel to the bottom and back.

In simple terms your fish finder acts first like a speaker (sending the sound out) and then switches over to a microphone (picking the sound up).

Now anything that gets in the path, sends back an echo which can be interpreted by your fish finders electronics as bottom, fish, rocks, logs.
