CHIRP Technology Advantages
Revolutionary Target Separation
Traditional single-frequency transducers send short pulses at one frequency, limiting target separation and detail. The SS175L's CHIRP technology continuously sweeps through the entire 40-75 kHz range, creating a "chirp" that provides:
- 5-10X Greater Detail: Enhanced resolution distinguishes individual fish in schools
- Superior Bottom Definition: Clear separation between bottom and near-bottom targets
- Extended Range: Longer pulse duration increases effective power and range
- Noise Reduction: Spread spectrum technology improves signal-to-noise ratio
- Structure Clarity: Precisely defines rocks, reefs, and underwater topography
Low-Frequency Advantages in Deep Water
The 40-75 kHz low-frequency range is specifically optimized for deep-water fishing applications:
- Deep Penetration: Lower frequencies travel farther in water with less absorption
- Wide Coverage: Broader beam pattern covers more area per pass
- Strong Returns: Better reflection from large fish and structure
- 50 kHz Coverage: Includes the popular 50 kHz fishing frequency
- Temperature Stability: Performance remains consistent across temperature variations

Frequently Asked Questions
What's the difference between low-frequency and high-frequency CHIRP?
Low-frequency CHIRP (like this 40-75 kHz transducer) is optimized for deep water over 600 feet, providing excellent penetration and wide coverage. High-frequency CHIRP offers better resolution in shallow water but has limited depth capability. This SS175L is specifically designed for deep-water fishing applications.
Can I use this transducer on a boat with deadrise greater than 7 degrees?
The 0° tilt version is optimized for hulls with 0-7° deadrise. For boats with greater deadrise angles, consider the SS175L with 12° or 20° tilt options (models 000-13775-001 or 000-13776-001) to ensure proper beam orientation perpendicular to the water surface.
How does the integrated temperature sensor work?
The SS175L includes a fast-response water temperature sensor that provides real-time temperature readings displayed on your fishfinder. Temperature data is crucial for locating thermoclines where fish concentrate, and the sensor responds quickly to temperature changes as you move through different water layers.
What's the maximum depth capability in real-world fishing conditions?
While rated to 10,000 feet maximum depth, real-world performance depends on water conditions, bottom type, and fishfinder settings. In typical deep-sea fishing conditions (clear water, moderate seas), expect excellent performance to 2,000-4,000 feet with good target separation and bottom definition throughout the water column.
Is professional installation required for through-hull transducers?
Professional installation is strongly recommended for through-hull transducers. The installation involves cutting a hole in your boat's hull and requires proper sealing, fairing, and cable routing. Marine electronics technicians have the tools, experience, and insurance to ensure a watertight installation that maintains your boat's structural integrity.
Can this transducer distinguish between fish and structure?
Yes, the CHIRP technology provides exceptional target separation that allows experienced users to distinguish between fish and structure based on return characteristics. Fish typically show as softer, curved returns that may move between pings, while structure appears as hard, consistent returns. The high resolution reveals individual fish within schools and fish near structure.
