HDI Skimmer M/H 455/800 X-Sonic 9-pin black depth sounder - 6 m cable

The Navico HDI Skimmer M/H transducer integrates Hybrid Dual Imaging (HDI) technology, combining Broadband Sounder and DownScan Imaging™. This delivers detailed underwater views and improved target separation.

This transducer operates on different frequencies depending on the technology used:

For DownScan Imaging™, it uses frequencies of 455 kHz and 800 kHz. For Broadband Sounder, it uses Medium/High CHIRP frequencies (83 kHz and 200 kHz).

Maximum depth varies depending on the technology and frequency:

With DownScan Imaging™, the sounder can reach a maximum depth of 90 meters (300 feet) at 455 kHz. With Broadband Sounder, it can reach a maximum depth of 304 meters (1000 feet) at 200 kHz.

Yes, this transducer has an integrated water temperature sensor, providing depth and temperature data to your display.

The weight of the HDI Skimmer M/H transducer without its cable is 0.11 kg (0.24 lbs).

The transducer comes with a 6-metre (20-foot) cable, providing flexibility for installation on your vessel.

The DownScan Imaging™ beam angles are 6.4° at 455 kHz and 12° at 800 kHz, providing a detailed view of underwater structure.

The beam angles for the Broadband Sounder are 38° at 83 kHz and 17° at 200 kHz, optimized for fish detection and bottom reading.

The transducer can operate effectively at speeds up to 60 knots (70 mph) when mounted on the transom.

The transducer is designed to operate within a temperature range of 0°C to +50°C (32°F to +122°F). For storage, the range is -30°C to +70°C (-22°F to +158°F).

The Skimmer M/H HDI transducer is black.

This transducer is compatible with Lowrance and Simrad units equipped with a 9-pin X-Sonic transducer port.

The transducer is equipped with a 9-pin X-Sonic connector, ensuring a secure and direct connection with compatible displays.

The HDI Skimmer M/H transducer can be mounted on the transom of your boat or on an outboard motor. It can also be installed through-hull (shoot-thru-hull) in some cases.

For optimal performance, the transducer must be installed in an area with undisturbed water flow. It is recommended to avoid zones behind planing strakes or flaps, which can create turbulence.

To minimize interference and ensure clear readings, avoid mounting the depth sounder transducer behind planing strakes or near flaps, as these elements can create water turbulence.

Recommended pilot hole diameters depend on your hull material:

For soft materials such as plywood, use a 3.7–4.0 mm (5/32") drill bit. For hard materials such as fiberglass, acrylic, or hardwood, use a 4.1–4.7 mm (3/16") drill bit.

Yes, it is essential to apply a high-quality marine sealant/adhesive to through-hull fittings, whether above or below the waterline, to ensure watertightness and the longevity of the installation.

Yes, the HDI Skimmer M/H transducer can be through-hull mounted (shoot-thru-hull). However, it is important to note that through-hull transducers cannot function effectively through wooden hulls.

Yes, the transducer integrates the Broadband Sounder which uses Medium/High CHIRP frequencies (83/200 kHz), making it compatible with CHIRP systems on your device.
