How does a Lowrance fishfinder device work?

These fishfinder devices from Lowrance are designed to locate aquatic life underwater using sonar technology or similar derivations of it. The fishfinder displays the location of a fish on the units small digital screen, usually either an LCD or CRT screen. In addition to sonar technology, contemporary fishfinding devices may also use GPS location, radar, digital compassing, or HDS data to help you locate the fish you seek.

The transducer on your device will send signals into the waves. These echoes these waves produce will be sent back to your transducer for data processing. After this data is processed, it will send it to your screen as an image. The screen displays any fish in the water as unique symbols to differentiate them from anything else the echoes may find.

What is CHIRP technology?

CHIRP is a form of sonar that uses a compressed and intense form of a radiated pulse to put a long signal into the water. This signal sweeps over a broad range of frequencies and sends them along to the transducer. The transducer begins to vibrate at a low frequency when the pulses begin and gradually moves to higher frequencies as it receives more pings.
