XSONIC 50/200 HDI depth sounder (20°)

This transducer operates on two frequency ranges for traditional sonar and two for DownScan Imaging™:

For traditional sonar: 50 kHz and 200 kHz. For DownScan Imaging™: 455 kHz and 800 kHz.

The XSONIC 50/200 HDI transducer offers different depth capabilities depending on the technology used:

In traditional sonar mode (50/200 kHz), the maximum depth is 350 metres (1200 feet). In DownScan Imaging™ mode (455/800 kHz), the maximum depth is 350 feet.

This transducer integrates two main sonar technologies for a complete underwater view:

Traditional sonar, which provides a classic view of the seabed and fish. DownScan Imaging™, which delivers detailed images of the underwater structure with photographic clarity.

The XSONIC 50/200 HDI transducer housing is made of bronze, providing robustness and durability suitable for marine environments.

Yes, the XSONIC 50/200 HDI fishfinder is equipped with a fast-response water temperature sensor integrated into the transducer, allowing this essential data to be collected for fishing and navigation.

The transducer is supplied with a 10-metre (33-foot) cable, providing sufficient flexibility for installation on most sailboats.

The XSONIC 50/200 HDI transducer is fitted with a 9-pin black connector, designed for reliable connection to compatible devices.

The XSONIC 50/200 HDI transducer is specifically designed with a 20-degree tilted element, making it optimized for boats with a deadrise angle of 20° to 24°. This ensures improved sonar beam performance.

DownScan Imaging™ is a sonar technology that provides near-photographic images of underwater structures, fish, and submerged objects. It uses higher frequencies (455/800 kHz) for improved clarity and target separation, making it easy to distinguish fish from structures.

For traditional sonar, the XSONIC 50/200 HDI transducer offers the following beam widths:

At 50 kHz: 45°, for wide coverage and good deep penetration.
At 200 kHz: 11°, for more detailed and precise target detection.

For DownScan Imaging™, beam widths are designed for high resolution:

At 455 kHz: 2.8° (fore-aft) by 56° (port-starboard). At 800 kHz: 1.6° (fore-aft) by 32° (port-starboard). These narrow fore-aft and wide port-starboard beams provide detailed images of structures beneath the boat.

The XSONIC 50/200 HDI transducer, featuring a bronze housing, is recommended for installation on fiberglass or wooden hulls. It is imperative never to install a bronze transducer on a metal hull to avoid electrolytic corrosion.

During installation, it is important to:

Always wear personal protective equipment (safety glasses, dust mask, hearing protection). Lubricate all O-rings to ensure perfect sealing. Never pull, carry, or hold the transducer by its cable to avoid damaging internal connections. Use marine-grade sealant for applications below the waterline. Never use solvents that could damage the plastic parts of the transducer.

For optimal performance, choose a location where:

Water flows smoothly under the hull 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 sources of electrical interference or radiation (thrusters, other machinery, other sounders).The deadrise angle is minimal so the beam is directed toward the bottom.There is sufficient vertical space inside the boat for installation and securing.

For the basic installation, you will need:

Safety glasses, dust mask, hearing protection.Electric drill with a 10 mm (3/8") or larger chuck.Drill bit: 3 mm or 1/8".Hole saw of the appropriate size for the outer hull hole.Sandpaper.Mild household detergent or low-solvent cleaner (such as alcohol) to clean the area.Marine sealant suitable for below-waterline applications.

Yes, using marine sealant is mandatory to ensure perfect and durable watertightness. It is recommended to apply a 2 mm (1/16") thick layer around the flange and on the side wall of the housing. The sealant must extend beyond the combined thickness of the hull, washer, and nut to ensure proper sealing of the threads.

To maintain your depth sounder’s performance and protect it from marine fouling, you can apply an antifouling coating specifically designed for transducers, such as Foulfree. This type of coating creates an ultra-smooth surface that prevents marine growth from adhering, without affecting transducer performance and in a non-toxic manner.

The XSONIC 50/200 HDI transducer is designed to be compatible with Lowrance and Navico devices that support HDI (Hybrid Dual Imaging) technology, traditional 50/200 kHz sonar, and DownScan Imaging™ 455/800 kHz, and which use a 9-pin black connector.

No, the XSONIC 50/200 HDI transducer, which has a bronze housing, must never be installed on an aluminum hull or any other type of metal hull. This would cause electrolytic corrosion, damaging both the hull and the transducer.

This XSONIC 50/200 HDI transducer is a through-hull bronze unit, specifically designed for installation on fiberglass or wooden hulls. Never install a bronze housing in a metal hull due to the risk of electrolytic corrosion.

Thanks to its 20-degree tilted element, this transducer is optimized for boats with a deadrise angle between 20° and 24°. This design ensures optimal sonar beam performance by compensating for hull tilt to direct the beam toward the bottom.
