What customers say
This professional grade transducer earns high praise for its exceptional deep water performance and reliability. Users consistently report crystal clear target separation and solid bottom lock, even beyond one thousand feet. The wide beam element is invaluable for effectively locating pelagic species and bait balls. While the initial investment is significant, serious offshore anglers agree the resulting clarity and resolution justify the premium cost. A key consideration is installation; due to its size and weight, achieving optimal performance often requires professional mounting to manage turbulence effectively. Overall, its unmatched performance solidifies its reputation as a benchmark in marine electronics.
Know before you buy
This transducer is specifically designed for compatibility with Furuno TZT3 12, 16, and 19-inch displays. It features a standard 12-pin connector for a seamless plug-and-play installation with these units.
The High Wide beamwidth provides a broader view of the upper water column, which is excellent for tracking baitfish and game fish near the surface. It offers significantly more coverage than a traditional narrow-beam transducer, helping you spot targets that might otherwise be missed.
While it is a high-performance unit, it is optimized for boats 25 feet and larger. Due to the size and mounting requirements of the transom bracket, ensure you have adequate flat surface area on your transom before installation.
Yes, the TM275C-LHW includes a built-in water temperature sensor. This data is transmitted directly to your TZT3 display, allowing you to monitor thermal layers while you fish.
Dual-channel CHIRP allows you to run both low and high frequencies simultaneously. This gives you the best of both worlds: the low frequency provides deep-water penetration for finding structure, while the high frequency delivers high-resolution detail for identifying individual fish.
The transducer includes a durable stainless steel kick-up bracket designed to protect the unit if it strikes an underwater object. Periodically check the mounting hardware for tightness and ensure the bracket is free of marine growth to maintain optimal sonar performance.
