Furuno CA28F-24H Professional Marine Transducer - 28kHz 3kW Rubber Coated External Mount

Note: This model has been discontinued by Furuno. Furuno recommends the CA28BL-12HR as an alternative.

The Furuno CA28F-24H represents professional-grade marine sonar technology designed for serious commercial fishing and deep-water applications. This 28kHz, 3kW rubber-coated transducer delivers exceptional bottom tracking and target identification capabilities in challenging offshore environments where precision fish finding is critical to operational success.

Professional 28kHz Low-Frequency Performance

The CA28F-24H operates at 28kHz, making it ideal for deep-water commercial fishing applications where maximum depth penetration is essential. This low-frequency design excels in water depths exceeding 500 feet, providing reliable bottom tracking and fish detection in the challenging conditions encountered by commercial fishing vessels, charter boats, and offshore sportfishing craft.

3kW High-Power Output

With 3kW of transmit power, the CA28F-24H delivers exceptional range and target separation capabilities required for professional marine applications. This high-power output ensures strong return signals even in deep water, providing the signal strength necessary for accurate fish identification and bottom composition analysis in demanding offshore environments.

Durable Rubber-Coated Construction

• Marine-Grade Rubber Housing: Protects internal components from impact damage during hull installation
• Saltwater Corrosion Resistance: Engineered for long-term exposure to harsh marine environments
• Impact Protection: Rubber coating provides cushioning against underwater debris and installation stress
• Professional Durability: Built to withstand the demanding conditions of commercial fishing operations

External Hull Mount Installation

The CA28F-24H features external mounting design for through-hull installation, providing direct water contact for optimal acoustic performance. This installation method ensures maximum signal transmission efficiency while allowing for precise positioning on the vessel's hull for optimal beam coverage.

Frequently Asked Questions

Q: Why is 28kHz frequency preferred for deep-water applications?

A: Lower frequencies like 28kHz penetrate deeper into the water column with less signal loss, making them ideal for deep-water fishing where maximum range is more important than high-resolution target separation.

Q: What's the maximum operating depth for the CA28F-24H?

A: Depth capability depends on the connected sonar system, but 28kHz transducers typically perform well in depths exceeding 1,000 feet when paired with appropriate high-power fishfinders.

Q: Can this transducer be used for recreational fishing?

A: While designed for professional applications, the CA28F-24H can be used on recreational vessels with compatible sonar systems, though it may provide more capability than needed for typical recreational fishing depths.

Q: What transducer plug is required for installation?

A: A separate Furuno transducer plug must be purchased to connect the CA28F-24H to your sonar system. Consult your Furuno dealer for the appropriate plug model.

Q: Why has this model been discontinued?

A: Manufacturers regularly update product lines with improved technology. Furuno has introduced newer models like the CA28BL-12HR that offer enhanced performance and features.

Q: Can I still get service support for the CA28F-24H?

A: Contact Furuno customer service for information about service availability for discontinued models. They may recommend upgrading to current equivalent models for long-term support.
