Detailed description

Designed for simplified installation, the AIRMAR P79D is a 600 W interior transducer operating on dual frequencies of 50/200 kHz. This model is intended for depth readings only, providing a no-drill solution for solid fiberglass hulls and aluminum hulls with a thickness of less than 3.8 mm.

Installation and Versatility

The P79D transducer features an adjustable-angle design that allows vertical orientation of the transducer even on hulls with deadrise angles from 0° to 22°. This ensures optimal echo return and stable depth performance. Installation is performed by bonding the plastic mounting base inside the hull, then filling with non-toxic antifreeze (propylene glycol) to facilitate sound transmission.

Technical Specifications

With a peak power of 600 W, the AIRMAR P79D offers a maximum range of 305 meters (1000 feet) at 50 kHz and 183 meters (600 feet) at 200 kHz. Beam widths are 45° for the 50 kHz frequency and 12° for 200 kHz, ensuring precise detection. Its diameter is 98 mm and its weight is 2.3 kg. It is compatible with vessels up to 8 meters in overall length and maintains high-speed performance when properly installed at the stern. The standard connection cable is 10 meters long and typically features a 10-pin Furuno connector.

Expert opinion

« AIRMAR P79D: the depth option without drilling for sensitive hulls »

The AIRMAR P79D transducer stands out as a technically relevant solution for recreational boaters seeking reliable depth measurement without compromising hull integrity. Its main advantage lies in its "in-hull" installation concept without drilling, ideal for trailerable boats, rigid inflatables, racing sailboats, or any vessel where maintaining a smooth hull is critical.

Installation requires using epoxy resin or marine sealant to secure the mounting base inside the solid fiberglass or thin aluminum hull (less than 3.8 mm). Filling with propylene glycol ensures effective acoustic coupling. Its tiltable design is a major asset, allowing adjustment of the transducer orientation to compensate for deadrise angles up to 22 degrees, ensuring a vertical beam and optimal echo returns even at high speeds. It is crucial to select a location free of air bubbles or foam layers for maximum performance.

This model is specifically designed for depth measurement only. For applications requiring temperature or speed data, additional sensors must be integrated. With 600W power and 50/200kHz frequencies, it is a suitable choice for most coastal and semi-offshore applications on boats up to approximately 8 meters, where a simple, non-invasive installation is preferred over a through-hull transducer.

Frequently Asked Questions

Need help? Contact us

What are the main features of the AIRMAR P79D transducer?

The AIRMAR P79D transducer is a 600 W inside-the-hull depth sounder designed for depth detection only. It operates on dual frequencies of 50/200 kHz and is made of plastic. Its tiltable design allows installation without drilling on certain hull types.

Does the P79D transducer measure anything other than depth?

No, the AIRMAR P79D transducer is specifically designed for depth measurements only. It does not provide temperature or speed data.

What is the transmit power of the AIRMAR P79D transducer?

The AIRMAR P79D transducer has a peak power of 600 W, which provides good depth detection range.

What are the operating frequencies of the P79D depth sounder?

The P79D transducer is a dual-frequency model operating at 50 kHz and 200 kHz. These frequencies provide versatility for different marine environments and depths.

What is the maximum depth detection range of the P79D transducer?

The AIRMAR P79D transducer provides a maximum depth detection range of:

305 metres (1000 feet) at 50 kHz183 metres (600 feet) at 200 kHz

What are the beam angles of the P79D transducer at 50 kHz and 200 kHz?

The AIRMAR P79D transducer beam widths are as follows:

45° for the 50 kHz frequency12° for the 200 kHz frequencyThese angles ensure precise detection beneath the vessel.

What is the construction material of the AIRMAR P79D transducer?

The AIRMAR P79D transducer is made of plastic, making it suitable for an indoor adhesive installation.

What are the dimensions and weight of the P79D depth sounder?

The AIRMAR P79D transducer has a diameter of 98 mm and weighs 2.3 kg.

Is the AIRMAR P79D transducer suitable for high-speed boats?

Yes, the AIRMAR P79D transducer is designed to maintain reliable performance at high speed, provided it is correctly installed at the stern of the boat.

How is the AIRMAR P79D transducer installed?

Installing the P79D transducer is simplified and does not require drilling the hull. It is mounted by bonding the plastic mounting base inside the hull. The base must then be filled with non-toxic antifreeze (propylene glycol) to facilitate sound transmission.

Is it necessary to drill the hull to install the P79D transducer?

No, one of the advantages of the AIRMAR P79D transducer is that it is designed for installation without drilling the hull. It adheres directly to the inside.

Which product is required to fill the mounting base of the depth sounder?

To ensure optimal sound transmission and proper operation of the transducer, the mounting base must be filled with a non-toxic antifreeze, such as propylene glycol.

How does the P79D transducer adapt to different hull angles?

The P79D transducer features an adjustable-angle design. This allows vertical orientation of the transducer, even on hulls with deadrise angles from 0° to 22°, ensuring optimal echo return.

Are there specific recommendations for the installation location of the depth sounder?

For better performance, especially at high speed, it is recommended to install the AIRMAR P79D transducer at the stern of the boat, inside the hull.

Which hull types is the AIRMAR P79D depth sounder compatible with?

The AIRMAR P79D transducer is compatible with:

Solid fiberglass hulls.Aluminum hulls with a thickness of less than 3.8 mm.

Can the P79D transducer be installed on any aluminum hull?

No, the P79D transducer is compatible with aluminum hulls, but only if their thickness is less than 3.8 mm. For thicker aluminum hulls, this model is not recommended.
