Lowrance Head Unit Only Fishfinders
Lowrance has manufactured marine and fishing products, such as fishfinders and similar devices, for more than 50 years. Its fishfinder units, such as the Elite Ti, HDS Carbon, and HDS Gen3 series, employ technologies such as radar, sonar, GPS, and TotalScan that may help you find fish and other aquatic life. Lowrance fishfinder head units are available in a variety of sizes, frequencies, and screen resolutions to meet your needs and preferences.
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 unit's 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.
In what sizes are Lowrance fishfinders available?You can purchase a fishfinding device based on how large or small you would like your screen to be. The most common measurements for digital fish finder screens include:
- 5 inches
- 6 inches
- 7 inches
- 8 inches
- 9 inches
- 12 inches
These fishfinder devices operate at a few common frequencies, including:
- 50 KHz
- 200 KHz
- Increments over 200 KHz

- 480 by 480 pixels
- 480 by 640 pixels
- 600 by 800 pixels
- 800 by 480 pixels

- GPS functionality
- Networking
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.
