Detailed description

The P79S SmartDucer glue-on depth sounder transducer from RAYMARINE, part number T70278, is a versatile solution for acquiring depth and temperature data without hull drilling. Designed for internal installation, it transmits data directly over the NMEA 2000 network, eliminating the need for a dedicated external sounder module. This approach simplifies system architecture and reduces integration costs for vessels equipped with MFDs or NMEA 2000-compatible instruments.

SmartDucer technology and connectivity

The SmartDucer concept integrates signal processing electronics directly into the transducer. The P79S uses standard frequencies of 50 kHz and 200 kHz, providing coverage suitable for various depths and conditions. Connection is via a DeviceNet connector, compliant with NMEA 2000 specifications. RAYMARINE includes a SeaTalkNG adapter, ensuring plug-and-play integration with RAYMARINE navigation systems, similar to iTC-5 sensors or STNG modules.

Positioning and applications

Unlike traditional through-hull transducers such as the B744V or B164, which require drilling, the P79S is mounted inside the fiberglass hull using epoxy resin. This makes it ideal for owners seeking to avoid hull alterations or for racing sailboats where hydrodynamic drag must be minimized. While it may offer slight signal attenuation compared to a through-hull transducer, its performance remains suitable for coastal and offshore navigation up to significant depths. It serves as a practical alternative to external transducers for mid-sized boats, where installation simplicity is a key criterion.

« Technical analysis of the RAYMARINE P79S SmartDucer depth sounder: installation and integration »

The RAYMARINE P79S SmartDucer is a sound choice for monohull fiberglass boats where drilling the hull is undesirable. Its adhesive design, bonded with epoxy resin in an air-bubble-free area, ensures reliable signal transmission for depth and temperature.

This model is particularly relevant for recreational boaters seeking a simple and quick-to-install solution without the complexity of a through-hull transducer or an external fishfinder module. As a SmartDucer, it directly outputs NMEA 2000 data (via DeviceNet) to any compatible multifunction display or instrument, which is a significant advantage for system integration. The inclusion of the SeaTalkNG adapter further simplifies connection to existing RAYMARINE networks.

It is important to note that the P79S’s effectiveness depends on hull quality and installation. It is not recommended for wooden, metal, or sandwich (cored) hulls without specific and often complex preparation (sandwich cutting and filling). For boats requiring maximum fishfinder performance in deep water or for sport fishing, a through-hull transducer or a dedicated CHIRP fishfinder module may be more suitable, but for general navigation and safety, the P79S provides a competent and discreet solution.

Frequently Asked Questions

Need help? Contact us

How to install the Raymarine P79S SmartDucer transducer on my boat?

The P79S SmartDucer transducer is a glue-on transducer, meaning it is installed inside the fiberglass hull of your boat. The installation requires no drilling. It is fixed using epoxy resin in a suitable location on the hull, ensuring direct contact without bubbles with the hull material.

Do I need to drill the hull of my boat to install the P79S transducer?

No, one of the main advantages of the Raymarine P79S transducer is that it requires no hull drilling. It is a glue-on transducer designed to be installed inside a fiberglass hull, which greatly simplifies the installation process and preserves the hull's integrity.

Which Raymarine devices is the P79S transducer compatible with?

The P79S transducer is a SmartDucer that integrates signal processing electronics. It connects via a DeviceNet connector, compliant with NMEA 2000 specifications. A SeaTalkNG adapter is included, ensuring plug-and-play integration with Raymarine navigation systems compatible with NMEA 2000 and SeaTalkNG, such as multifunction displays (MFD) and instruments.

What is the SmartDucer technology integrated into the P79S?

SmartDucer refers to the signal processing electronics being directly integrated into the transducer itself. This eliminates the need for a separate dedicated sounder module, simplifying the navigation system architecture and reducing integration costs.

What is the advantage of a glue-on transducer like the P79S compared to a traditional through-hull transducer?

The main advantages of a glue-on transducer like the P79S are that it does not require drilling through the hull, preserving the boat's structural integrity and simplifying installation. Additionally, it adds no hydrodynamic drag, which is particularly valued on racing sailboats. While it may exhibit a slight signal attenuation compared to a through-hull transducer, its performance remains suitable for coastal and offshore navigation.

On which type of hull can the P79S transducer be installed?

The P79S transducer is specifically designed for installation on solid fiberglass hulls. It is not suitable for wooden, steel, aluminum hulls, or fiberglass hulls with a core (sandwich) without specific preparation to remove the core at the transducer location.
