XSONIC Airmar SS175M (20°)

The XSONIC Airmar SS175M (20°) transducer has a power output of 1 kW. This high power is designed for detailed underwater detection and excellent deep penetration.

This CHIRP transducer operates on a mid-frequency band ranging from 85 kHz to 135 kHz. This range provides a total bandwidth of 50 kHz, selected to balance deep-range capability and target resolution.

The XSONIC Airmar SS175M (20°) transducer can reach a maximum depth of 457 meters (1500 feet). This capability makes it suitable for detection in medium to deep waters.

Yes, this transducer integrates a depth sensor and a fast-response water temperature sensor, providing essential data for navigation and fishing.

The XSONIC Airmar SS175M (20°) transducer is supplied with a 10-metre (33-foot) cable and features a 9-pin connector.

This transducer’s CHIRP technology uses a mid-frequency band (85 kHz to 135 kHz) to strike an optimal balance between deep penetration and target resolution. This delivers sharp, detailed images of seabed structures and fish.

The XSONIC Airmar SS175M (20°) transducer offers a variable beam angle from 16° to 11°. This angle provides effective coverage beneath the boat and better target separation in mid to deep waters.

A CHIRP mid-frequency transducer, such as the SS175M, offers an excellent compromise between deep-sounding capability (a characteristic of low frequencies) and detailed target resolution (a characteristic of high frequencies). It is therefore highly versatile for fishing in varying depths.

The SS175M (20°) transducer is specifically designed with a 20° tilted element to compensate for keel angles ranging from 16° to 24°. This tilt ensures the sonar beam is directed straight downward for optimal performance.

The SS175M (20°) transducer’s stainless steel housing is compatible with all hull materials, including fiberglass, wood, and metal. For metal hulls, the supplied isolation ring must be used to prevent electrolytic corrosion.

It is crucial to choose a location where water flows smoothly, without bubbles or turbulence, and where the transducer remains continuously submerged. Avoid areas near water intakes, discharges, seams, or hull irregularities. For planing hulls, mount it at the rear, near the centerline and within the first lifting strakes.

CHIRP transducers generate more heat than traditional transducers. It is imperative to install them in a cool, well-ventilated location, away from the engine compartment, to prevent overheating and transducer failure. The transducer must always operate while submerged in water.

For installation, you will need the following tools:

Safety glasses, dust mask, hearing protectionAngle finder or digital levelElectric drill with a 10 mm (3/8") or larger chuck3 mm (1/8") drill bit95 mm (3-3/4") hole saw for fiberglass or wood hulls, or 105 mm (4-1/8") for metal hullsSandpaper, mild detergent or light solvent (alcohol)Marine sealant (suitable for below the waterline)3/16" Allen keySlip-joint pliers

The 20° tilted element compensates for your hull’s keel angle. During installation, ensure the arrow on top of the transducer points toward the keel or the boat’s centerline. This will align the internal element’s angle with your hull’s keel angle, maximizing echo returns.

Yes, applying a water-based antifouling paint is mandatory in saltwater to maintain the transducer's optimal performance and prevent marine fouling. Airmar certifies that the application of foul-release coatings, such as Foulfree, does not affect the transducer's performance.

Yes, the XSONIC Airmar SS175M (20°) transducer is a hardware accessory compatible with Lowrance sonars, sensors, transducers, scanners, and antennas, including those using Airmar Tilted Element technology. It features a 9-pin connector.

Yes, the stainless steel housing is compatible with aluminum hulls. However, it is critical to use the supplied isolation ring to isolate the housing from the metal hull and prevent electrolytic corrosion, as specified in the installation instructions.

No, it is imperative to never install a metallic transducer on a vessel equipped with a positive grounding system, as this could lead to electrolytic corrosion issues.

Yes, foul-release coatings such as Propspeed® Foulfree by Airmar are certified. These non-toxic products create an ultra-smooth surface that prevents marine fouling from adhering, ensuring optimal sonar performance and up to two years of protection.

The 20° angle of the XSONIC Airmar SS175M transducer refers to its Tilted Element™ design (tilted element).

This internal tilt is designed to compensate for the hull deadrise angle of your boat, ensuring that the sonar beam is directed straight downward for optimal performance. This fixed 20° transducer is specifically suited for hulls with a deadrise angle between 16° and 24° at the chosen mounting location.

Regarding hull material compatibility, the SS175M housing is made of stainless steel. This makes it compatible with all hull materials, including fiberglass, wood, and metal hulls. For metal hulls, it is important to ensure that the stainless steel housing is isolated from the metal hull to prevent electrolytic corrosion.
