Furuno 526ST-MSC Bronze Thru-Hull Multisensor w/ High-Speed Fairing Block, 600w (8-Pin)

The Furuno 526ST-MSC Bronze Thru-Hull Multisensor with High-Speed Fairing Block is a professional-grade dual-frequency sonar transducer designed for serious anglers and marine professionals who demand reliable fishfinding across a wide range of water depths and speeds. Operating at 600 watts of power across 50 and 200 kHz frequencies, this bronze thru-hull unit delivers the sensitivity and speed performance needed for both shallow-water structure location and deep offshore applications.

The dual-frequency design provides distinct beam angles—40 degrees at 50 kHz for broader coverage and 10 degrees at 200 kHz for precise target definition—allowing anglers to switch between wide-area scanning and detailed bottom composition analysis. The integrated high-speed fairing block enables reliable operation even at cruising speeds, eliminating the cavitation noise that degrades sonar quality on faster vessels. Onboard temperature and speed sensing capabilities eliminate the need for separate sensors. The 30-foot cable with 8-pin connector integrates seamlessly into standard Furuno systems and compatible chartplotters.

This transducer suits both weekend tournament anglers and commercial fishing operations where consistent performance under variable conditions is essential. Bronze construction resists galvanic corrosion in saltwater environments while maintaining acoustic efficiency. The thru-hull design eliminates the drag and turbulence associated with transom-mount alternatives, ideal for boats where hull mounting is feasible. Buyers should confirm system compatibility with their existing chartplotter before installation.

The 526ST-MSC represents the intersection of proven Furuno engineering and practical multi-frequency versatility—a transducer for anglers who understand that sonar quality directly impacts catch success.
