CHIRP Fishfinders transmit across a wide frequency band instead of using a single frequency. This is also known as “Frequency Modulation” or “Spread-Spectrum” Transmissions. These waveforms are typically of long duration and for example may start at 42 kHz and end at 65 kHz. Energy transmitted into the water can be 10 to 50 times greater than a traditional fishfinder. By storing the shape of the transmitted waveform in memory and comparing it to the received echoes using pattern matching techniques (also called pulse compression), it is possible to find targets within the noise and precisely determine their range with astounding accuracy.
- Extreme target detail and image resolution at all depths
- Precise separation between baitfish and gamefish
- Bottom discrimination of fish laying on the seabed
- Deep sounding accuracy down to 3,000 m (10,000’)
- Ability to detect targets at greater depths & higher speeds
- Ability to find targets within the noise (“snow” on the display)
