 What is the difference between FishFinder and GPS?

A fish finder unit uses SONAR technology to scan and give you a picture of the bottom. It does not provide navigation assistance, whereas a chartplotter uses GPS to help you navigate waterways safely. Each unit can be purchased separately or, more commonly, together as a combined unit.

How does a fish finder detect fish?

Fish finders detect the presence of fish primarily by detecting the air in their swim bladders. The air conserved in the swim bladder changes the sound path and reflects energy back. The fish finder detects this reflected energy and converts it into fish images on the screen.
