Product Description
Ensure a steadfast and reliable signal from your fish finder with the genuine Humminbird MHX XNTF Transom Mount Hardware kit (Part #740091-1). Engineered for durability and precision, this hardware kit provides a robust, fixed-style mounting solution for a wide array of Humminbird XNT series transducers. It is the ideal choice for anglers who demand a permanent, stable, and secure placement for their transducer to get the clearest, most consistent sonar readings on the water.
Product Overview and Technical Details
The Humminbird MHX XNTF is a complete transom mounting hardware kit designed as a direct replacement or upgrade for many standard Humminbird transducer mounts. Unlike "kick-up" style brackets that are designed to pivot upon impact, the MHX XNTF is a fixed mount. This rigid design minimizes transducer movement, flex, and vibration, especially at higher speeds or in choppy water conditions. For anglers who prioritize an uninterrupted, crystal-clear sonar picture over impact protection, a fixed mount is the superior choice.
This kit includes all the necessary components for a secure installation, including the main mounting bracket, transducer bracket plug, and associated stainless steel hardware.
Key Features:
- Fixed Mount Design: Offers maximum rigidity for a stable and consistent sonar signal.
- Durable Construction: Built to withstand the harsh marine environment.
- Genuine Humminbird Part: Ensures perfect fitment and compatibility with specified Humminbird products.
- Complete Kit: Includes all necessary hardware for a full installation on your boat's transom.
