SEIWA CHIRP technology

Higher resolution, less power, less noise


SW BBFF CHIRP and SEIWA SWx multifunction displays come with a CHIRP sonar to  offer  a high resolution view of targets for an efficient and sustainable fishing.

CHIRP stands for Compressed High-Intensity Radiated Pulse and is a game-changing  technology that has been used by the military, now finally available for professional and recreational sonar.

SEIWA CHIRP sonar transmits a longer pulse than traditional sonar, putting more energy into the water column  achieving: 

  • HD resolution and target definition

  • Greater ability to pull targets from the background noise

  • Improved bottom tracking at higher speeds

  • Improved bottom tracking at deeper depths 

Longer Pulse

Longer Pulse

While traditional sonar trasmit a powerful energy pulse, but short in duration, SEIWA CHIRP sonar can transmit  pulses that are much longer in duration.

Less Noise

Less Noise

A traditional sonar transmits about 1%  of the time, while SEIWA CHIRP sonar longer pulses put more energy into the water column, even though transmitting at lower peak power than traditional fishfinders, thus causing less noise. 

Depth and detail

Depth and detail

Different frequencies reveal different levels of detail. The higher the frequency, the higher the detail, but the lower is the depth that can be penetrated.  

To offer the best combination of depth and detail, SEIWA CHIRP sonar transmits a sweeping range of frequencies from 40 to 210kHz.

Which CHIRP frequencies should you choose?

Choose what's best for your activity

Low CHIRP

 

< 80 kHz 

It is used in deep water, it offers great depth performance identifying targets at all depths in the water column.

Best for depths: > 600 feet / > 180 m 

MEDIUM CHIRP

 

80 -160 kHz 

It can display a wider coverage area, scanning large areas more quickly, than high CHIRP. Higher resolution than low frequency CHIRP.    

Best for depths:  < 600 feet  / < 180 m

HIGH CHIRP

 

150 -210 kHz 

It offers high resolution for shallow water, highest detail for smaller objects. Best for inland and freshwater fishing activities.

Best for depths:  < 600 feet  / < 180 m

Never miss a thing

Smart marks from Fishfinder history to map


SEIWA ROMEO software features some special functions dedicated to fishing such as the Smart Marks on FF history!

Browse the Fish Finder history up to 5 minutes  and, if you find anything interesting, place a mark on it, you will find it on your chartplotter map! 

Then, with thanks to the Cursor Box smart function, just point the cursor on the mark’s position in the map to instantly view distance and bearing.

Select a Fishing Range

Advanced map option for easier fishing

 

You can select on your SEIWA charplotter a fishing range: when you know the fish are suspended over certain depths, highlight the range so you can quickly identify more places to check out!
 

*Function available with NAVIONICS charts.
