Furuno 455T-PR903 Side-Scan Thru-Hull Transducer Pair

The Furuno 455T-PR903 Side-Scan Thru-Hull Transducer Pair brings professional-grade imaging to anglers and boaters who demand clarity in structure, vegetation, and bottom composition. This paired transducer system is engineered for serious fishermen and survey professionals who rely on side-scan sonar to locate fish-holding cover, map underwater terrain, and navigate shallow or complex water bodies with confidence. Whether you're pursuing bass in a highland reservoir, scanning for walleye in a deep lake, or surveying coastal structure, this Furuno system delivers the detailed acoustic picture that separates productive fishing from guesswork.

Built around a dual 455 kHz CHIRP frequency architecture, the 455T-PR903 generates 150 watts of power on each side, allowing the transducer pair to paint high-resolution side-scan imagery across wide swaths of water column. The CHIRP frequency band of 445–465 kHz optimizes resolution for medium-range imaging—ideal for identifying individual rock formations, fallen timber, and subtle bottom changes that traditional single-frequency units miss. Constructed with stainless steel thru-hull housing for corrosion resistance and fitted with an integrated temperature sensor, the transducers withstand saltwater and freshwater environments alike. The 12-pin connector and 12-meter (40-foot) cable provide clean integration with compatible Furuno fishfinder and navigation systems, ensuring a reliable hardwired connection that won't degrade in rough seas or extended use.

Serious tournament anglers, charter captains, and boat surveyors benefit most from the 455T-PR903's dual-transducer architecture, which eliminates the compromises of single-element side-scan designs. Installation requires thru-hull mounting on both sides of the hull—typically amidship for optimal coverage—and compatibility with Furuno NavNet TZtouch2 and DFF1 series displays ensures seamless integration into modern pilothouse systems. The 40-foot cable length accommodates larger vessels and allows flexible transducer placement without performance loss. For anglers upgrading from traditional 2D sonar, the transition to side-scan imaging dramatically shortens the learning curve for reading bottom structure and positioning on productive zones.
