XSONIC Airmar SS175H-W (20°)

This is a 1 kW through-hull stainless steel transducer with CHIRP High-Wide technology. It is designed for fish detection and detailed seabed imaging, featuring a 20° tilted element to compensate for keel angle.

The XSONIC Airmar SS175H-W (20°) transducer has a power output of 1 kW.

It operates over a high and wide frequency range, from 150 to 250 kHz, thanks to its CHIRP High-Wide technology.

The transducer offers a constant beam width of 25°.

It can reach a maximum depth of 152 metres (500 feet).

This depth sounder provides depth data and features a fast-response water temperature sensor, plus fish detection and detailed bottom mapping.

The CHIRP High-Wide technology offers a coverage under the boat twice as extensive as traditional high-frequency narrow-beam depth sounders. This improves fish detection in the water column and generates clear fish arches with superior resolution and excellent target separation.

The housing of this depth sounder is made of stainless steel.

The transducer is supplied with a 10-metre (33-foot) cable.

The transducer is equipped with a 9-pin connector.

This transducer is designed with a fixed 20° tilted element, making it compatible with keel angles ranging from 16° to 24°.

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 isolation ring.

Yes, the stainless steel housing must be isolated from the metal hull to prevent electrolytic corrosion. An insulating ring is provided for this purpose. Ensure the washer rests against the hull and not against the insulating ring when tightening.

Choose a location where the water flow under the hull is smooth, with minimal bubbles and turbulence, and where the transducer will remain continuously submerged. Avoid areas in line or near water intakes, discharges, seams, or hull irregularities that could disrupt water flow. The transducer beam must not be obstructed by the keel or propeller shafts.

For planing hull boats, mount it well at the stern, near the centerline. For outboards and inboard/outboard (I/O) drives, place it just ahead of the engine(s). For inboards, install it well forward of the propeller or propeller shafts.

Yes, it is essential to apply suitable marine sealant to the entire inner surface of the strut and around the mounting hole below the waterline to ensure watertightness and prevent vibrations.

Yes, you can apply a water-based antifouling paint to the transducer. Airmar certifies that applying the Foulfree coating does not affect the transducer's performance. Never use solvents.

A minimum clearance of 178 mm (7 inches) inside the hull is required for the transducer housing, installation of the spacer, and tightening of the nut and adjustment screws.

The stainless-steel housing of this depth sounder is compatible with all hull materials, including fiberglass, wood, and metal. For metal hulls, insulation is required.

Yes, this transducer can be used with all types of boat propulsion.

This transducer is a compatible accessory for Navico CHIRP fishfinders (Lowrance, Simrad, B&G) equipped with a 9-pin connector.
