XSONIC Airmar SS175L (20°)

The XSONIC Airmar SS175L (20°) transducer is a 1 kW through-hull (thru-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 seabed down to a maximum depth of 762 meters (2500 feet) thanks to its 1 kW power and low-frequency CHIRP technology.

Low-frequency CHIRP technology offers several advantages:

Deep detection: It achieves great depths with excellent clarity.Increased resolution: It improves target separation, allowing you to distinguish baitfish, game fish, and underwater structures.Less sensitive to noise: 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 fast response.

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

The SS175L (20°) transducer offers a variable beam width 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 CHIRP low-frequency technology (40–60 kHz) and 1 kW power output, the SS175L (20°) depth sounder improves detection by providing:

Higher resolution to clearly distinguish targets.Better separation between baitfish, gamefish, and underwater structures.The 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 your hull material:

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 necessary to accommodate the isolation 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° tilted 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 antifouling coating to the transducer, especially in salt water. Airmar certifies that applying 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 fishfinders, 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 deadrise angles ranging from 16° to 24°. This ensures the sonar beam is vertically oriented 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 reliable connection with compatible devices.

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