Skimmer Sonde HST-DFSBL 50/200 kHz with Temperature Sensor

The NAVICO HST-DFSBL transducer operates on two primary frequencies: 50 kHz and 200 kHz. It uses CHIRP technology with low/high frequency.

The HST-DFSBL transducer can reach different depths depending on the frequency used:

At 50 kHz, the maximum depth is 914 meters (3000 feet). At 200 kHz, the maximum depth is 304 meters (1000 feet).

Yes, the NAVICO HST-DFSBL transducer is equipped with an integrated temperature sensor that allows measuring water temperature.

The HST-DFSBL transducer comes with a 6-metre (approximately 19.5-foot) cable.

The NAVICO HST-DFSBL transducer connects via a 7-pin blue connector.

The beam width of the HST-DFSBL transducer varies depending on the frequency:

At 50 kHz, the beam width is 29°. At 200 kHz, the beam width is 12°.

The weight of the HST-DFSBL transducer without its cable is 0.37 kg (approximately 0.81 lbs).

The HST-DFSBL transducer has a transmit power of 600 watts.

The HST-DFSBL transducer can operate within a temperature range of 0°C to +50°C (32°F to +122°F).

The HST-DFSBL transducer can be installed in several ways:

On the boat’s transom. By through-hull scanning (shoot-thru-hull).

The ideal mounting location for the HST-DFSBL transducer is an area with undisturbed water flow to ensure accurate readings.

Yes, it is not recommended to install the HST-DFSBL transducer behind the chines or near trim tabs, as these can cause turbulence and affect performance.

For installation, the recommended pilot hole diameters for screws of 10 mm diameter depend on the hull material:

For flexible materials (e.g., plywood), use a diameter of Ø 3.7–4.0 mm (5/32"). For rigid materials (e.g., fiberglass, acrylic, hardwood), use a diameter of Ø 4.1–4.7 mm (3/16").

Yes, it is recommended to apply a marine-grade sealant/adhesive suitable for above or below the waterline to the mounting holes.

No, through-hull scanning transducers cannot function effectively through wooden hulls.

The HST-DFSBL transducer is a hardware accessory compatible with Lowrance fishfinders. It is designed for units using a 7-pin blue connector and supporting 50/200 kHz frequencies.

Yes, the HST-DFSBL transducer uses CHIRP low/high frequency (50/200 kHz) technology, making it compatible with depth sounder systems that support this technology.

No, the HST-DFSBL transducer (low/high frequency) is not listed as compatible with mounting on an electric bow thruster. This option is typically reserved for mid/high-frequency transducers.

The HST-DFSBL transducer is specifically designed as an accessory compatible with Lowrance equipment, particularly those using the 7-pin blue connector. Compatibility with other brands is not guaranteed and is not mentioned in the specifications.

The NAVICO HST-DFSBL transducer is a Skimmer dual-frequency transducer operating at 50 kHz and 200 kHz (low/high CHIRP frequencies).

At 50 kHz, it provides a maximum depth of 914 meters (3000 feet) with a 29° beam width, ideal for deep-water detection. At 200 kHz, it delivers detailed resolution up to 304 meters (1000 feet) with a 12° beam width, suitable for fish identification and bottom structure in shallower waters. It also includes a temperature sensor and comes with a 6-meter (20-foot) cable connecting via a 7-pin blue connector. This transducer supports a maximum speed of 60 knots (70 mph) when mounted on the transom.
