XSONIC 50/200 HDI depth sounder (0°)

The NAVICO XSONIC 50/200 HDI (0°) transducer is a bronze through-hull transducer designed for detailed underwater imaging. It integrates Hybrid Dual Imaging (HDI) technology, combining traditional sonar with DownScan imaging for comprehensive views of the underwater environment and structures. Its 0° tilted element is optimized for hulls with minimal deadrise.

This transducer operates at traditional sonar frequencies of 50 kHz and 200 kHz.

For DownScan imaging, the transducer uses frequencies of 455 kHz and 800 kHz.

The NAVICO XSONIC 50/200 HDI (0°) transducer enables depth detection up to 350 meters (1200 feet). Performance may vary depending on the connected fishfinder unit.

The housing of this depth sounder is made of bronze, designed for through-hull installation.

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

Hybrid Dual Imaging (HDI) technology combines two types of sonar: traditional sonar (for fish detection and depth) and DownScan imaging (for detailed views of underwater structures and the seabed). This combination provides a more complete understanding of the underwater environment.

At 50 kHz, the beam width of a traditional sonar is 45°. At 200 kHz, the beam width of a traditional sonar is 11°.

At 455 kHz, the DownScan beam widths are 2.8° (fore-aft) by 56° (port-starboard). At 800 kHz, the DownScan beam widths are 1.6° (fore-aft) by 32° (port-starboard).

The 0° tilted element of this transducer is optimized for hulls with low deadrise, ensuring optimal performance up to a deadrise angle of 7° and adaptable up to 12°.

No, it is strongly discouraged to install a bronze housing on a metal hull (including aluminum) as this can cause electrolytic corrosion.

The through-hull bronze housing of this depth sounder is recommended and designed for installation on fiberglass or wooden hulls.

Safety glasses, dust mask, and hearing protection.Electric drill (chuck size Ø 10mm or 3/8" or larger).Drill bit Ø 3mm or 1/8".Hole saw (Ø 51mm or 2" for the outer hole).Chamfering tool (for flush-mount housings; not specified for this model but useful for preparation).Sandpaper.Mild household detergent or low-solvent cleaner (e.g., alcohol).Marine sealant (suitable for below the waterline).Adjustable wrench (for metal housing installation; not applicable here but mentioned in the general guide).Cable ties.

After drilling a pilot hole, use a hole saw of the appropriate size to cut a hole perpendicular to the hull from the outside. Then sand and clean the area around the hole, inside and outside, to ensure proper adhesion of marine sealant. If the hull is metal, remove all burrs with a file and sandpaper.

Yes, it is essential to apply a layer of marine sealant approximately 2mm (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 hull nut to ensure perfect watertightness and keep the nut in place.

Yes, for a fiberglass hull with a core, specific instructions must be followed. This typically involves drilling a larger hole inside the hull (Ø 60mm or 2-3/8") compared to the outer hole (Ø 51mm or 2"), then sealing the core with fiberglass and resin, or a cylinder, wax, and casting epoxy, before installing the transducer to prevent water absorption by the core.

If the hull nut is plastic, tighten it by hand only and do not overtighten. If the hull nut is metal, tighten it with a multi-grip pliers. For fiberglass hulls with a core, do not overtighten to avoid crushing the hull. For wooden hulls, allow the wood to swell before fully tightening the hull nut.

Choose a location where water flows smoothly, with minimal bubbles and turbulence, especially at high speed. The transducer must remain continuously submerged, its beam must not be obstructed by the keel or propeller shaft, and the location should be away from interference sources (propellers, machinery, other depth sounders, cables). Prefer an area with minimal deadrise angle and adequate vertical space inside the boat.

This transducer is an essential accessory compatible with Lowrance devices, particularly those using Sonar / Sensor / Transducer / Scanner / Antenna / HDI technology.

The transducer is equipped with a 9-pin black connector, ensuring compatibility with compatible fishfinder units.
