XSONIC 50/200 HDI depth sounder (12°)

The XSONIC 50/200 HDI transducer integrates Hybrid Dual Imaging (HDI) technology. This technology combines traditional CHIRP sonar with high-definition DownScan imaging to provide a detailed view of the seabed and underwater structures.

For traditional sonar, the XSONIC 50/200 HDI transducer uses frequencies of 50/200 kHz, providing an extended CHIRP coverage for effective fish and structure detection.

The DownScan imaging of this depth sounder operates on frequencies of 455/800 kHz, providing high-resolution images of underwater structures, wrecks, and fish schools.

This transducer features a 12-degree tilted element. This design is optimized for hulls with a moderate keel angle, ensuring the transducer face remains perpendicular to the water flow for optimal performance.

The XSONIC 50/200 HDI transducer housing is made of bronze, making it robust and suitable for marine use in specific environments.

The XSONIC 50/200 HDI transducer is supplied with a 10-metre (33-foot) cable, providing flexibility for installation aboard your vessel.

This transducer has a 9-pin black connector, designed for reliable connection to compatible devices.

Beam widths for traditional sonar are 45° at 50 kHz and 11° at 200 kHz, enabling effective detection and coverage suited to varying depths and conditions.

In DownScan mode, the beam widths are 2.8° (fore-aft) and 56° (port-starboard) at 455 kHz, and 1.6° (fore-aft) and 32° (port-starboard) at 800 kHz, providing detailed images of the seabed and structures.

Yes, thanks to its Hybrid Dual Imaging (HDI) technology combining traditional CHIRP sonar and DownScan imaging, this sounder is perfectly suited for detailed underwater imaging, precise depth detection, identification of bottom contours, wrecks, and fish schools.

The through-hull transducer with a bronze housing is recommended for fiberglass or wooden hulls. It is strongly advised against installing it on a metal hull due to the risk of electrolytic corrosion.

This transducer is optimized for hulls with a keel angle up to 7°, but it can effectively accommodate a maximum keel angle of 12°.

For installation, you will need:

Safety glasses, dust mask, and hearing protectionAn electric drill with a 10 mm (3/8") or larger chuckA 3 mm (1/8") drill bitA 51 mm (2") hole sawSandpaper and mild detergent (or weak solvent like alcohol)Marine sealant suitable for below the waterlineAn additional washer if the aluminum hull is less than 6 mm (1/4") thickA multi-grip pliers (for metal hull nuts)

For optimal performance, choose a location where:

Water flows smoothly, with minimal bubbles and turbulence, especially at high speed.The transducer will remain continuously submerged at all speeds.The transducer beam will not be obstructed by the keel or propeller shaft.The location is away from interference sources such as propellers, machinery, other fishfinders, or cables.The deadrise angle is minimal so the beam is directed toward the bottom.There is sufficient vertical space inside the boat for installation and tightening.Avoid mounting the transducer in line or near water intakes/outlets, or behind strakes, fittings, or hull irregularities that could disrupt water flow.

You will need to drill a pilot hole of Ø 3mm (1/8"), then use a hole saw of Ø 51mm (2") for the main hole in the hull to properly install the transducer.

Yes, it is essential to apply a layer of marine sealant approximately 2 mm (1/16") thick around the flange and on the side wall of the housing. The sealant must extend higher than the combined thickness of the hull, washer, and nut to ensure perfect watertightness and keep the nut in place.

After inserting the transducer housing into the hole with sealant, tighten the hull nut from the inside. Immediately check for leaks when the boat is launched and monitor closely for at least three hours. Ensure all surfaces to be sealed are clean and dry before applying the sealant.

Yes, a transducer with a bronze housing is recommended for wooden hulls. It is advisable to let the wood swell slightly before fully tightening the hull nut to avoid damaging the hull or the transducer.

To protect the transducer from marine fouling, you can apply a non-toxic, environmentally friendly antifouling coating such as Foulfree. This type of coating creates an ultra-smooth surface that prevents marine growth from adhering to the transducer, ensuring optimal sonar performance over the long term.

This transducer is a hardware accessory compatible with Lowrance systems, including the brand’s sonar, sensors, HDI transducers, and antennas.
