XSONIC Airmar R509LH-W

The XSONIC Airmar R509LH-W transducer is a through-hull sonar device designed specifically for professional fishing and commercial applications. It uses CHIRP technology with a wide beam to provide superior target detection and detail separation, even for fish lying on the bottom.

The R509LH-W transducer operates on two distinct frequency bands:

Low frequency: between 28 kHz and 60 kHz. High frequency: between 150 kHz and 250 kHz.

The XSONIC Airmar R509LH-W transducer’s transmit power varies by frequency band:

The low-frequency band delivers 3 kW of power. The high-frequency band delivers 1 kW of power.

The maximum depth capabilities of the R509LH-W depend on the frequency band used:

The low-frequency band (28–60 kHz) can reach a detection depth of up to 3,048 m (10,000 ft). The high-frequency band (150–250 kHz) reaches a maximum depth of 152 m (500 ft).

For the low-frequency band (28-60 kHz), the beam width of the R509LH-W transducer is variable:

From 23° to 9° on the port-starboard axis. From 11° to 5° on the fore-aft axis.

The high-frequency band (150–250 kHz) of the R509LH-W transducer maintains a constant beam width of 25°.

The XSONIC Airmar R509LH-W transducer is equipped with 25 internal broadband ceramic assemblies, ensuring precise resolution and target detection.

The XSONIC Airmar R509LH-W transducer comes with a 10 m (33 ft) cable.

The R509LH-W transducer is equipped with a dual 9-pin connector for connection to compatible sonar modules.

Yes, the XSONIC Airmar R509LH-W transducer is specifically designed for professional fishermen and commercial applications, providing advanced sonar performance for target detection.

This transducer uses CHIRP wide-beam technology, providing increased coverage beneath the hull and sharper, more detailed sonar images.

The XSONIC Airmar R509LH-W transducer requires a compatible sonar module to operate. It is compatible with the NSSevo3S or S5100 modules, which are part of the Navico ecosystem (Lowrance, Simrad, B&G).

For installing a through-hull transducer, the essential tools and materials include:

Safety glasses, dust mask, and hearing protection.Electric drill and appropriate drill bits.Hole saw (specific size not provided for this model; professional consultation recommended for a 'pocket mount').Chamfering tool (for flush-mount housings).Sandpaper.Mild household detergent or low-solvent cleaner (such as alcohol).File (for metal hulls, if applicable).Marine sealant suitable for below the waterline.Additional washers if required.Slip-joint pliers (for metal housings, if applicable).Cable ties.Anti-fouling coating based on water (mandatory in saltwater).For a 'pocket mount' installation such as the R509LH-W, professional installation is strongly recommended.

Yes, it is highly recommended to apply antifouling coating to the transducer. Applying a coating such as Foulfree, Airmar-certified, does not affect the transducer's performance. This prevents the buildup of marine organisms that can significantly degrade sonar signal quality and image.

The choice of location is crucial for performance. Ensure that:

The water flow under the hull is smooth, with minimal bubbles and turbulence, especially at high speed.The transducer remains continuously submerged at all speeds.The transducer’s beam is not obstructed by the keel or propeller shaft.The location is clear of interference sources (propellers, machinery, other depth sounders, cables).The deadrise angle is minimal to ensure the beam is correctly directed toward the seabed.There is adequate vertical space inside the boat for housing and tightening the nuts.

Yes, Foulfree is certified by Airmar as having no detrimental effect on transducers. It is also non-toxic and environmentally friendly, releasing no toxins once cured. It is a foul-release coating that prevents marine growth from adhering to the surface.

The XSONIC Airmar R509LH-W transducer operates on two distinct frequency bands for optimal performance:

Low frequency (CHIRP low): Operates between 28 kHz and 60 kHz with a power of 3 kW. It can detect targets down to 3,048 meters (10,000 feet) in depth, with beam widths ranging from 23° to 9° (port-starboard) and from 11° to 5° (bow-stern). High frequency (CHIRP high): Operates between 150 kHz and 250 kHz with a power of 1 kW. Its maximum depth is 152 meters (500 feet), and it maintains a constant beam width of 25°. This transducer is equipped with 25 internal broadband ceramic assemblies for precise resolution and detection.

To function correctly, the XSONIC Airmar R509LH-W transducer requires the use of a compatible sonar module. It is essential to have an NSSevo3S or S5100 sonar module.

Marine growth on a transducer can severely impair sonar performance. It can cause significant turbulence noise on the display when the boat is moving, or reduce the amount of detail and clarity of the received sonar image while fishing.

To prevent this fouling, Airmar and Propspeed® offer Foulfree, a non-toxic, durable, and ultra-smooth coating. This coating prevents marine organisms from attaching to the transducer surface, ensuring optimal performance. Once applied, Foulfree can protect the transducer for up to two years without releasing toxins into the environment.
