520-5PSD: Plastic thru-hull transducer 600W; 50/200 kHz; 46/10° beam angle

The FURUNO 520-5PSD transducer has a transmit power of 600 Watts RMS. This power enables effective and precise detection of seabeds and underwater targets.

This transducer is dual-frequency, meaning it operates on two distinct frequencies: 50 kHz and 200 kHz. The 50 kHz frequency is ideal for deep-water detection and wide-area coverage, while the 200 kHz frequency is optimized for fine discrimination in shallower waters.

The FURUNO 520-5PSD transducer uses different beam angles depending on the frequency:

At 50 kHz, the beam angle is 46°. At 200 kHz, the beam angle is 10°. These angles provide versatility for deep-water detection and precision in shallower waters.

The FURUNO 520-5PSD transducer housing is made of impact- and marine-chemical-resistant plastic. It also features an acoustic window in urethane for optimal performance.

The 520-5PSD transducer is a through-hull type. This means it is installed by drilling a hole in the boat's hull, with the transducer body passing through the hull to be in direct contact with the water.

The FURUNO 520-5PSD transducer comes with an 8-meter cable. This cable is terminated with a 10-pin connector, specifically designed for FURUNO echo sounders and compatible sounder modules.

The physical dimensions of the FURUNO 520-5PSD transducer are approximately 12 cm in height by 6.8 cm in width. For through-hull installation, a hole diameter of 22 mm (0.875 inches) is required in the hull.

The FURUNO 520-5PSD transducer is compatible with fiberglass or metal hulls. Its rugged plastic construction makes it suitable for these materials.

For optimal performance, the transducer must be installed in an area of the hull where water flow is as laminar as possible, meaning with minimal turbulence and air bubbles. It is generally recommended to position it away from propellers, keels, other transducers, and water intakes. The goal is to ensure the acoustic beam is not obstructed and that the transducer remains permanently submerged.

The FURUNO 520-5PSD transducer is a standard through-hull transducer. A fairing block is usually not required if the installation area on the hull is relatively flat. However, on hulls with a steep deadrise angle, using a fairing block can improve performance by ensuring the transducer’s beam is directed vertically toward the bottom, reducing distortion.

To ensure perfect watertightness when through-hull installing the 520-5PSD transducer, it is critical to use a high-quality marine sealant (such as polyurethane or marine-grade silicone) on the contact surfaces between the transducer, hull, and mounting nuts. Follow the installation manual instructions carefully for tightening the nuts to properly compress the sealant and prevent any water infiltration.

The 520-5PSD transducer is a straight transducer. For hulls with significant deadrise, it can be installed, but it is critical to ensure the acoustic beam is directed vertically downward. In some cases, this may require careful planning of the installation location or, as previously mentioned, the use of a fairing block to correct the angle and optimize detection performance.

The FURUNO 520-5PSD transducer is compatible with a range of Furuno fishfinders and chartplotters, including the following models:

FCV-628, FCV-588, GP-1670F, GP-1870F, GP-1871F, GP-1971F, FTZ Touch 2. It is designed to operate optimally with these units.

Yes, when connected to compatible Furuno units, the 520-5PSD transducer can activate and support advanced features. This includes bottom discrimination, which allows analysis of seabed composition (rock, sand, gravel, mud), and Accu-Fish technology, which helps identify the size of individual fish.

The FURUNO 520-5PSD transducer is specifically designed with a 10-pin connector and optimized electrical specifications for FURUNO echo sounders and sounder modules. While third-party adapters may exist for some brands, compatibility and optimal performance are only guaranteed with Furuno equipment for which it is intended.

Yes, the FURUNO 520-5PSD transducer is compatible with several Furuno multifunction displays (MFD) that include a fishfinder function. Models such as the GP1670F, GP1870F, GP1871F, GP1971F, and TZTouch2, listed in the compatibility chart, are examples of MFDs with which this transducer will operate.

The FURUNO 520-5PSD is a traditional analog transducer that outputs raw depth data to a fishfinder or MFD. It is not directly compatible with NMEA 2000. The display unit (fishfinder or MFD) to which the transducer is connected must be compatible; if so, it will convert the raw data into NMEA 2000 format for sharing with other equipment on the boat’s network.
