Furuno 235-IHF 235KHZ P79 NMEA NMEA 2000 IN-HULL Transducer Product Description
Furuno 235-IHF In-Hull Digital Depth Sensor with NMEA 2000
Advanced In-Hull Depth Sensing Without Hull Penetration
The Furuno 235-IHF revolutionizes depth sensing with cutting-edge in-hull technology that eliminates the need for through-hull installation. This professional-grade digital depth sensor uses advanced 235kHz sonar technology and NMEA 2000 connectivity to deliver precise depth measurements up to 150 meters while maintaining complete hull integrity. Built with proven Airmar P79 housing design and featuring layered plastic urethane acoustic window technology.
Revolutionary In-Hull Technology
No-Penetration Installation
The 235-IHF's innovative in-hull design bonds directly to the interior hull surface, transmitting sonar signals through advanced acoustic window technology. This eliminates the risk of through-hull leaks while providing accurate depth readings through fiberglass hulls with deadrise angles from 0° to 22°.
Digital NMEA 2000 Integration
Native NMEA 2000 connectivity ensures seamless integration with modern marine electronics networks. The sensor provides real-time depth data with 1-second update intervals and supports full plug-and-play compatibility with NMEA 2000 certified marine electronics.
Professional Sonar Performance
The 235kHz frequency delivers exceptional bottom detection and resolution, providing reliable depth measurements from 0.5 to 150 meters. The 7° beamwidth ensures accurate readings while the advanced digital processing eliminates noise and interference common in analog systems.
Technical Specifications
Installation & Application Benefits

Frequently Asked Questions
How does in-hull mounting work compared to through-hull?
In-hull mounting uses advanced acoustic window technology to transmit sonar signals through the hull material without requiring holes. While through-hull provides slightly better performance, in-hull offers significant installation advantages and eliminates leak risks.
What hull types are compatible with the 235-IHF?
The sensor works best with solid fiberglass hulls having deadrise angles from 0° to 22°. Cored hulls, metal hulls, or hulls with significant deadrise angles may not provide optimal acoustic coupling.
Can this sensor be used for fishing applications?
The 235-IHF is primarily designed for depth measurement and navigation safety. While it provides bottom detection, dedicated fishfinders offer better fish detection capabilities and higher resolution for fishing applications.
How do I install the sensor on my hull?
Installation requires proper surface preparation, marine-grade adhesive or mounting hardware, and careful positioning for optimal acoustic coupling. Professional installation is recommended to ensure proper performance and avoid installation issues.
Is the sensor compatible with non-Furuno electronics?
Yes, the NMEA 2000 output is industry-standard and compatible with any NMEA 2000 certified marine electronics including chartplotters, MFDs, and instrument displays from various manufacturers.
NMEA 2000 Network Planning
The 235-IHF requires proper NMEA 2000 network installation with backbone power supply and termination resistors. The sensor draws 200mA and has a Load Equivalency Number (LEN) of 4, which must be considered in network power calculations. Professional marine electronics installation ensures optimal network performance and compliance with NMEA standards.
