XSONIC Airmar SS75M (12°)

The XSONIC Airmar SS75M (12°) is a through-hull CHIRP transducer with a tilted element, designed for depth detection and rapid water temperature measurement. This 600W RMS transducer uses mid CHIRP technology to provide enhanced seafloor resolution.

This transducer has a 600W RMS power output and operates on a CHIRP mid-band frequency range from 80 kHz to 130 kHz. This provides a total bandwidth of 50 kHz for detailed detection.

The XSONIC Airmar SS75M (12°) can reach depths up to 274 meters (900 feet), making it suitable for shallow and medium-depth waters.

The CHIRP medium technology provides increased resolution, up to 5 to 10 times higher, for bottom detection. This makes it easier to distinguish between baitfish, game fish, and underwater structures, improving sonar image clarity.

Yes, the XSONIC Airmar SS75M (12°) is equipped with a temperature sensor for fast and accurate water temperature measurement.

The depth sounder housing is made of stainless steel, ensuring durability and compatibility with various hull materials.

The transducer is supplied with a 10-metre (33-foot) cable and has a 9-pin connector.

The stainless steel housing of the depth sounder is compatible with all hull materials, including fiberglass, wood, steel, and aluminum. For metal hulls, it is mandatory to use the provided isolation ring to prevent electrolytic corrosion.

The XSONIC Airmar SS75M (12°) is a model with a 12° tilted element. It is specifically designed to compensate for hull trim angles ranging from 6° to 15°. It is crucial to match the tilt angle of the transducer to the hull trim angle at the mounting location to ensure the sonar beam is directed straight to the bottom.

Yes, this transducer is an essential accessory compatible with Lowrance sonar/sensor/transducer/scanner/antenna systems, including Airmar Tilted Element models.

Yes, the XSONIC Airmar SS75M (12°) transducer can be installed on a metal hull. However, it is mandatory to use the provided isolation ring to isolate the stainless-steel housing from the metal hull. This isolation is essential to prevent electrolytic corrosion.

During installation, take the following precautions:

Always wear safety glasses, a dust mask, and hearing protection. Immediately check for leaks once the boat is in the water. Never operate the depth sounder out of the water to prevent overheating. Do not install the depth sounder in the engine compartment or any other hot area. The arrow on top of the depth sounder must point toward the keel or the boat’s centerline. Never pull, carry, or hold the depth sounder by its cable. Never use solvents for cleaning, as they can damage plastic components.

For optimal performance, the transducer must be installed in a location where:

Water flows smoothly, with minimal bubbles and turbulence.The transducer is continuously submerged in water.The transducer beam is not obstructed by the keel or propeller shaft.Away from sources of electrical interference or radiation.In a cool, well-ventilated area (for CHIRP transducers to prevent overheating).The exact location will depend on your boat's hull type (displacement, planing, etc.).

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

For fiberglass or wooden hulls, use a 70 mm (2-13/16") hole saw for the outside of the hull. For metal hulls, use a 79 mm (3-1/8") hole saw for the outside of the hull. For cored fiberglass hulls, an 80 mm (3-1/8") hole saw is also required for the inside of the hull. A 3 mm (1/8") pilot hole must be drilled first.

For installation, you will need the following tools and materials:

Safety glasses, dust mask, hearing protectionLevel or digital inclinometerElectric drill with 10 mm (3/8") or larger chuck3 mm (1/8") drill bitHole saw (see table for hull material-specific sizes)SandpaperMild detergent or low-solvent cleaner (e.g., alcohol)File (for metal hull installation)Marine sealant (suitable for below the waterline)Adjustable wrench (for metal housing installation)Cable tiesAnti-fouling paint (water-based, mandatory in saltwater)For cored fiberglass hulls: fiberglass cloth and resin, or a cylinder, wax, tape, and casting epoxy resin are also required.

Yes, applying water-based antifouling paint is mandatory for the transducer when used in salt water. Airmar certifies that applying Foulfree coating to its transducers does not result in any performance loss. This coating is a non-toxic and durable solution that prevents marine growth from adhering to the surface.

CHIRP transducers generate more heat than traditional transducers. To prevent overheating and transducer failure, it is crucial to install it in a cool, well-ventilated location away from the engine. The transducer must always operate in water and installation instructions provided by the manufacturer must be strictly followed.

The XSONIC Airmar SS75M (12°) has a beam angle that varies from 24° to 16°, providing effective coverage for fish and underwater structure detection.

Yes, the XSONIC Airmar SS75M (12°) transducer is compatible with all hull materials thanks to its stainless steel housing.

For metal hulls (steel or aluminum), it is mandatory to use the provided isolation ring during installation. This prevents electrolytic corrosion and ensures a secure, firm mounting of the transducer.

The 12° tilt angle of the Airmar SS75M XSONIC transducer is specifically designed to compensate for the deadrise angles of your boat’s hull. For this model, it is suitable for hulls with a deadrise angle between 6° and 15° at the mounting location.

To ensure optimal performance, you must measure the deadrise angle of your hull at the location where you plan to install the transducer. Use an inclinometer or a digital level to obtain an accurate measurement.

During installation, it is crucial that the arrow on the top of the transducer points toward the keel or the centerline of the boat. This ensures the transducer’s internal element is correctly aligned with the hull’s deadrise angle.
