XSONIC Airmar SS175L (20°)

The XSONIC Airmar SS175L (20°) is a 1 kW through-hull transducer. It is designed for depth detection and water temperature measurement using low-frequency CHIRP technology.

This transducer uses a Low-CHIRP frequency range from 40 to 60 kHz. This frequency band is optimized for deep-water detection and improved target separation.

The XSONIC Airmar SS175L (20°) transducer can detect the bottom down to a maximum depth of 762 meters (2500 feet) thanks to its 1 kW power and low-frequency CHIRP technology.

The CHIRP low-frequency technology offers several advantages:

Deep detection: It enables reaching great depths with excellent clarity.
Increased resolution: It improves target separation, allowing the distinction of baitfish, game fish, and underwater structures.
Less noise-sensitive: It is less affected by noise, enabling better detection even at high boat speeds.

Yes, the XSONIC Airmar SS175L (20°) transducer integrates a water temperature sensor that provides data with rapid response.

Airmar's Xducer ID® technology is a feature that enables automatic recognition of the transducer by the compatible device it is connected to. This simplifies configuration and optimizes sonar system performance.

The SS175L transducer (20°) provides a variable beam width ranging from 32° to 21° across its low-frequency CHIRP range (40-60 kHz). A wider beam width covers a larger area beneath the boat.

The XSONIC Airmar SS175L (20°) transducer housing is made of stainless steel. This material ensures robustness and compatibility with all hull types.

Thanks to its low-frequency CHIRP technology (40-60 kHz) and 1 kW power output, the SS175L (20°) fishfinder improves detection by providing:

Higher resolution to clearly distinguish targets.Better separation between baitfish, game fish, and underwater structures.Ability to sound deeper while maintaining image clarity.

The XSONIC Airmar SS175L (20°) transducer has a transmit power of 1 kW. This high power is essential for reaching great depths and obtaining clear echo returns.

The diameter of the hole to drill depends on the material of your hull:

For fiberglass or wooden hulls, a 95 mm (3-3/4") hole is required. For metal hulls, a 105 mm (4-1/8") hole is needed to accommodate the insulation ring.

During installation, the arrow on top of the transducer must point toward the keel or the boat’s centerline. This orientation ensures the 20°-inclined element correctly compensates for the hull angle, directing the sonar beam vertically toward the seabed.

CHIRP transducers generate more heat. To prevent overheating and failure of the SS175L (20°) transducer:

Install it in a cool, well-ventilated area, away from the engine compartment. Ensure the transducer is always submerged in water during operation. Never operate it in air.

Yes, it is strongly recommended to apply an antifouling coating to the transducer, especially in saltwater. Airmar certifies that applying the Foulfree coating does not affect the transducer's performance and protects against marine growth.

For optimal performance, avoid installing the transducer in the following areas:

In line with or near water intake or discharge openings.Behind strakes, fittings, or hull irregularities that could disrupt water flow.In areas where water is turbulent or contains bubbles, especially at high speed.Where the transducer beam could be obstructed by the keel or propeller shaft.Near sources of electrical interference or radiation (propellers, engines, other sounders, cables).

When installing the SS175L (20°) transducer with a stainless steel housing on a metal hull (steel or aluminum), it is critical to use the provided isolation ring. This ring must be installed to isolate the stainless steel housing from the metal hull to prevent electrolytic corrosion.

The XSONIC Airmar SS175L transducer is specifically designed with a 20° tilted element to compensate for hull angles ranging from 16° to 24°. This ensures the sonar beam is oriented vertically toward the seabed for optimal detection.

The SS175L (20°) transducer is recommended for vessels up to 11 meters (36 feet). Its stainless steel housing makes it compatible with all hull types, including fiberglass, wood, steel, and aluminum.

The XSONIC Airmar SS175L (20°) transducer is equipped with a 9-pin connector, ensuring a reliable connection with compatible devices.

The XSONIC Airmar SS175L (20°) transducer is supplied with a 10-metre (33-foot) cable.
