Differences between CHIRP and Broadband Fish Finders

If you move Deeper into the fish finders, you’ll find that even fish finders are categorized into two types like most of the other electronic devices. Different types of fish finders are hinged on the technologies used in them. As it’s obvious, with the time passing, new technologies are being introduced rapidly in the diverse fields of life. Similar is the case for the fish finders.

So I’ve decided to elaborate here these fish finders, their technologies, and differences. Two most known fish finders are:

Broadband or Traditional Fish Finder

First off, I’m going to explore the basic and commonly used fish finder i.e. traditional or broadband fish finder. Unlike CHIRP fish finders, broadband fish finders use a single frequency for their functionality. As they use single-frequency sonar that’s why they’re known as Broadband.

Their range of frequency is either 200 kHz or 83 KHz, 50 KHz because they carry only a single frequency wave. So you can only utilize a single frequency with these fish finders. Broadband fish finder is dependent on echoes and pings generated by their transducers and objects underwater.

It sends sonar waves or sound signals into water through the transducer and then collects the reflected waves in the form of echoes from underwater objects. Broadband fish finder uses the sonar technology that works best in terms of bottom tracking, offering the predator fish’s display, tracking of bait fishes as well as identifying the fishes’ location as compared to the CHIRP fish finder. Furthermore, advantages of broadband fish finder over other fish finders can be:

  • Target detection
  • Target size estimation
  • Tracking moving target by Doppler techniques of Broadband

CHIRP Fish Finder

In the second place, I’ll talk about CHIRP fish finders which are relatively more efficient than broadband fish finders. The abbreviation of CHIRP is Compressed High- Intensity Radar Pulse which was initially used by Airmar Technology Corporation in its transducers. Literally, it can be said as frequency modulated sonar. In CHIRP fish finder, diverse mixes of frequencies are being used without any important adjustment.

With CHIRP fish finders, fishers can most likely utilize the multiple frequencies’ range of 200 KHz, 50 kHz, 28 kHz, and 38 kHz. Additionally fishers can switch to the frequencies in between the given frequencies. Fishers get most exceptional clarity of their prey and target under water and it doesn’t matter either in deeper water or shallower water.

Some other differences and advantages of CHIRP fish finders as compared to broadband fish finders are:

  • Essentially increased execution at high pace
  • Better capacity of depth
  • Extended base and fish identification

CHIRP fish finder’s enhanced target definition along with the ability to find its target at a high pace despite the noise signals make this finder a priority for the fishers. The sound energy conveyed into the water by CHIRP transducer is 10 to 1000 times huge than broadband fish finder and even the echo which returns back is more superior than the one transmitted by the broadband fish finder’s transducer.
