Built-In Dual Spectrum Chirp Sonar: Keeps your transducer and wiring completely concealed and protected running everything through the trolling motor's shaft. By covering a wide range of frequencies, Humminbird®'s CHIRP produces more accurate, more detailed returns of fish, structure and the bottom than traditional sonar.
CHIRP stands for “Compressed High Intensity Radar Pulse.” That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t. How’s that? CHIRP scans the water for fish similar to the way the seek function on your truck’s radio scans the airwaves for FM stations. By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure and the bottom.

Frequencies for Dual Spectrum CHIRP (DSC)
- Full: 150-220 kHz
- Narrow: 180-240 kHz
- Wide: 140-200 kHz
Cone Angle for Dual Spectrum CHIRP (DSC) transducer
Dual Spectrum CHIRP sonar provides conical coverage directly below the boat. The beam can be adjusted to show the full, narrow, or wide frequency range. The sonar returns are displayed on the Sonar (2D) Views.
-
Full: 150-220 kHz
- Great for target separation
- Default Mode
-
Narrow: 180-240 kHz
- 25° beam
- Increased bottom detail
-
Wide: 140-200 kHz
- 42° beam
- Maximizes coverage
- Great for vertical jigging
High Wide Low-Q CHIRP
- Improved target separation.
- Differentiate between two targets.
- Identify fish sitting right off the bottom.
- Outstanding fish arches due to the 42 beam.
Dual Spectrum CHIRP (DSC) Temperature Sensing
The DSC transducer has an array of built-in temperature sensors that will display water temperature on most major fishfinder brands that have this feature.
Humminbird Compatibility for Dual Spectrum CHIRP (DSC)
Dual Spectrum Chirp transducers are tested and optimized for compatibility with Humminbird fishfinders. Results many vary when motors with Built-In Dual Spectrum Chirp are used in conjunction with outside fishfinder brands.
Compatible with:
- All APEX models
- All SOLIX models
- All XPLORE models
- HELIX with CHIRP G2/G2N and Newer

Minn Kota Trolling Motors that Offer the Dual Spectrum CHIRP DSC Transducer
We offer the Dual Spectrum CHIRP transducer on the select motors from the following freshwater bow-mount trolling motor series: Ultrex, Fortrex, Ulterra, Terrova, and PowerDrive.
If your fishfinder is not listed on the Dual Spectrum CHIRP (DSC) compatibility list
We only offer Dual Spectrum CHIRP (DSC) adapter cables for fish finder models listed on the Dual Spectrum CHIRP (DSC) compatibility list. Other fish finders not listed may work, however they have not been tested or qualified by Minn Kota and the fish finder manufacturer. The qualification program is ongoing to add additional fish finders to our compatibility list.
Testing the performance of the Dual Spectrum CHIRP (DSC) transducer to verify it is functioning properly
You can test the depth finder with the OEM (Original Equipment Manufacturer) supplied transducer. Compare the performance with the DSC transducer. If depth finder does not function properly with either transducer, the display may be faulty.
Upgrading a Built-in Universal Sonar 2 Transducer to a Built-in Dual Spectrum CHIRP (DSC)
Unfortunately we do not support modifying your motor from a Universal Sonar 2 transducer to a Dual Spectrum CHIRP transducer as it would be cost prohibitive.
