Furuno 520-IHD (P79) In-Hull Transducer - Revolutionary Shoot-Through Technology
Advanced sonar performance without hull penetration. The Furuno 520-IHD (P79) In-Hull Transducer (Part Number 520-IHD) represents a breakthrough in marine transducer technology, delivering powerful 600W performance through innovative shoot-through design. This professional-grade transducer eliminates the need for through-hull installation while providing exceptional depth detection up to 1000 feet with dual frequency 50/200 kHz operation.
Revolutionary Shoot-Through Technology
- 600W High Power Performance - Professional-grade power for maximum depth penetration and target detection
- Innovative Wet-Box Design - Unique liquid-filled chamber optimizes sound transmission through fiberglass hulls
- No Hull Penetration Required - Eliminates through-hull drilling, maintaining hull integrity and warranty
- Deadrise Compensation - Automatic adjustment for hull deadrise angles up to 22 degrees
- Dual Frequency Operation - 50/200 kHz frequencies with optimized beam angles for all fishing conditions
- Twist-Lock Installation - Separate transducer element locks into bonded base for secure mounting
- High-Speed Performance - Maintains bottom tracking and target detection at cruising speeds
Advanced P79 Shoot-Through Design
Wet-Box Technology
Innovative Liquid Coupling: Unlike traditional "puck" style transducers, the P79 features a unique wet-box design where the base is permanently bonded to the hull and filled with acoustically matched liquid. The separate transducer element then attaches with a secure twist-lock mechanism, creating optimal sound transmission through the liquid medium.
Deadrise Compensation System
- Automatic Adjustment: Compensates for hull deadrise angles from 0° to 22°
- Vertical Beam Orientation: Ensures optimal beam angle regardless of hull shape
- Accurate Depth Reading: Maintains precision depth measurement on V-hull designs
- Universal Compatibility: Works with most fiberglass boat hull configurations
Sound Transmission Efficiency
Optimized Acoustic Coupling
The liquid-filled wet-box creates superior acoustic coupling compared to air-gap installations, maximizing power transfer and signal clarity.
Minimal Signal Loss
Advanced design minimizes energy loss through hull transmission, maintaining strong signal strength for deep water performance.
Enhanced Sensitivity
Superior acoustic coupling provides increased sensitivity for detection of smaller targets and better bottom discrimination.

Sailing Yachts
Excellent for sailboats where minimizing through-hull fittings is critical for safety and performance. Installation doesn't affect hull strength or sailing characteristics.
Tournament Fishing
High-power performance and fast bottom tracking make it ideal for competitive fishing where sonar performance is critical for success.
Cruising Boats
Safe installation without hull penetration is perfect for cruising boats where reliability and reduced through-hull complexity are priorities.
Performance Advantages
- Deep Water Capability: 600W power provides excellent performance to 1000 feet
- High-Speed Bottom Tracking: Maintains lock on bottom at cruising speeds
- Superior Target Separation: Dual frequency operation optimizes fish detection
- Structure Definition: Clear bottom composition and contour reading
- Reduced Interference: In-hull mounting eliminates prop wash and cavitation effects
Professional Installation Process
Pre-Installation Requirements
- Hull Assessment: Verify solid fiberglass construction without foam core in installation area
- Location Selection: Choose area with smooth hull contour and minimal deadrise angle
- Access Planning: Ensure adequate internal access for base bonding and cable routing
- Tools and Materials: Marine-grade bonding compound and professional installation tools required
- Environmental Conditions: Installation requires dry conditions and appropriate temperature
Installation Process Overview
- Hull Preparation: Clean and prepare bonding surface on interior hull
- Base Positioning: Position wet-box base accounting for deadrise angle compensation
- Permanent Bonding: Bond base to hull using marine-grade structural adhesive
- Liquid Filling: Fill wet-box with acoustically matched coupling liquid
- Element Installation: Secure transducer element with twist-lock mechanism
- Cable Management: Route 30-foot cable to fishfinder location
- System Testing: Verify performance and optimize settings
Critical Installation Factors
Hull Compatibility
Designed specifically for solid fiberglass (GRP) hulls. Not suitable for aluminum, steel, or foam-cored fiberglass constructions.
Deadrise Compensation
Automatic compensation works for deadrise angles up to 22°, ensuring vertical beam orientation for accurate depth readings.
Professional Installation Required
Proper bonding and liquid filling require professional installation to ensure optimal performance and prevent leaks.
Frequently Asked Questions
How does in-hull installation compare to through-hull performance?
The P79's innovative wet-box design with liquid coupling provides performance very close to through-hull installations while eliminating hull penetration. The 600W power and optimized acoustic coupling ensure excellent depth capability and target detection, making it suitable for serious fishing applications.
What boats are suitable for this transducer?
The 520-IHD is designed for solid fiberglass (GRP) boats with hull deadrise angles up to 22 degrees. It's not suitable for aluminum, steel, or foam-cored fiberglass hulls. The installation area must have solid fiberglass construction for proper bonding and sound transmission.
Can I install this transducer myself?
Professional installation is strongly recommended. The process involves permanent bonding to the hull, proper liquid filling, and precise positioning for optimal performance. Incorrect installation can result in poor performance, leaks, or damage to your boat. Certified marine electronics technicians have the expertise and materials for proper installation.
How does the deadrise compensation work?
The P79 design automatically compensates for hull deadrise angles up to 22 degrees by adjusting the transducer element orientation within the wet-box. This ensures the sonar beam remains vertically oriented regardless of hull angle, providing accurate depth readings and optimal fish detection performance.
What maintenance does this transducer require?
The in-hull design requires minimal maintenance since it's protected inside the boat. Periodically check that the transducer element remains properly seated in the wet-box and verify the liquid level hasn't dropped. The exterior hull surface should be kept clean for optimal sound transmission.
