Navico xSonic P79 Adjustable 200/50kHz In-Hull Transducer | 9-Pin
The Navico xSonic P79 600W In-Hull Transducer provides reliable 50/200kHz depth tracking with a drill-free, adjustable-deadrise installation for solid fiberglass boats.

iable Depth Tracking Without Hull Penetration
The Navico xSonic P79 is an entry-level, 600-watt plastic in-hull transducer designed for straightforward, drill-free installation and reliable standard depth imaging. Engineered for marine navigation, this model provides accurate readings for boaters seeking a basic depth-only solution.
Adjustable Deadrise for Optimal Performance
Featuring an adjustable deadrise angle that accommodates 0 to 22 degrees, the xSonic P79 makes installation a snap. This flexibility ensures the transducer can be properly oriented on a variety of hull shapes, maximizing sonar efficiency directly through the boat's hull.
Dual-Frequency 50/200kHz Operation
The P79 operates on 50 to 200 kHz frequencies, generating a beamwidth of 45 to 12 degrees. It supports an operational depth range of 800 to 1,200 feet, providing dependable bottom tracking in varied marine environments. The unit includes a 33-foot cable and utilizes a 9-pin connection.
Installation Limitations and Compatibility
This in-hull transducer is designed exclusively for solid fiberglass hulls with a maximum thickness of 5/8 of an inch. It is strictly not recommended for cored hulls. The transducer operates as a standard-imaging, depth-only sensor and does not supply speed data, water temperature, or CHIRP sonar.

FAQs
What is the Navico xSonic P79?
The Navico xSonic P79 is a 600-watt, dual-frequency, plastic in-hull transducer designed to measure water depth through a suitable solid fiberglass hull. Its in-hull installation keeps the exterior of the boat free of protruding transducer hardware and does not require drilling through the hull.
What frequencies does the Navico xSonic P79 operate on?
The Navico xSonic P79 operates at 50 kHz and 200 kHz. It uses conventional dual-frequency sonar, with a 45-degree beamwidth at 50 kHz and a 12-degree beamwidth at 200 kHz.
What is the maximum depth range of the Navico xSonic P79 transducer?
The Navico xSonic P79 has a published depth performance of up to 1,000 feet at 50 kHz and 600 feet at 200 kHz. Actual depth performance depends on water conditions, bottom composition, installation quality, and the connected sonar equipment.
Does the Navico xSonic P79 read water temperature or boat speed?
No. The Navico xSonic P79 is a depth-only transducer. It does not include water temperature or boat speed sensing.
Can the Navico xSonic P79 be installed on a cored fiberglass hull?
The Navico xSonic P79 is designed for installation over solid fiberglass. It should not be positioned over untreated foam, balsa, or other core material because these materials can interfere with sonar transmission. Cored fiberglass installations require a suitable installation procedure to protect the core and maintain proper acoustic performance.
Does the Navico xSonic P79 support CHIRP sonar?
No. The Navico xSonic P79 is a conventional 50/200 kHz dual-frequency transducer, not a CHIRP transducer. Verify that your fishfinder or sonar module supports conventional 50/200 kHz operation.
What type of connector does the Navico xSonic P79 use?
The Navico xSonic P79, part number 000-13942-001, uses a 9-pin Navico xSonic connector. Check the connector and transducer compatibility requirements of your fishfinder or sonar module before purchasing.
How long is the transducer cable for the Navico xSonic P79?
The Navico xSonic P79 includes a 10-metre (33-foot) cable.
What deadrise angles can the Navico xSonic P79 accommodate?
The Navico xSonic P79 has an adjustable mounting base that accommodates hull deadrise angles from 2 to 22 degrees, helping orient the sonar beam vertically through the hull.
What type of hull is suitable for the Navico xSonic P79?
The Navico xSonic P79 is designed primarily for solid fiberglass hulls. A suitable installation location must provide a clear acoustic path through the hull for reliable depth readings.
