Furuno 455T-SS903 Side-Scan Stainless Steel Thru-Hull Transducer

The Furuno 455T-SS903 Side-Scan Stainless Steel Thru-Hull Transducer is a professional-grade imaging tool designed for anglers and boaters who demand high-resolution sonar clarity in saltwater and freshwater environments. After years on the water, serious fishermen know that side-scan sonar reveals structure, baitfish, and bottom composition with photographic precision—transforming how you locate productive fishing zones. This thru-hull transducer combines Furuno's engineering expertise with corrosion-resistant stainless steel construction, making it the choice for vessels that operate in harsh marine conditions where durability directly impacts fishing success.

The 455T-SS903 operates at 455 kHz using CHIRP technology across a 445–465 kHz band, delivering superior target separation and reduced noise compared to single-frequency alternatives. The transducer generates 150 watts of power on each side, enabling penetration to depths where trophy fish hold, while the integrated temperature sensor provides real-time water data vital for seasonal fishing patterns. Its stainless steel thru-hull housing withstands prolonged saltwater exposure without degradation, and the 12-pin connector paired with a 40-foot cable accommodates installation on boats of varying hull configurations and console distances.

Professional guides, tournament anglers, and dedicated recreational boaters benefit most from side-scan transducers like the 455T-SS903 when paired with compatible Furuno chartplotters and multifunction displays. Thru-hull installation requires cutting a precise opening through the hull bottom and careful bedding to prevent water intrusion, making professional installation advisable for most boaters. This transducer excels in both saltwater and freshwater applications, from coastal flats and reefs to deep lakes and reservoirs, wherever mapping the underwater environment translates directly to more consistent catches and safer navigation.
