Furuno 525ST-PWC Plastic TM Multisensor, 600W (8-Pin)

The Furuno 525ST-PWC Plastic Transom Mount Multisensor is a 600-watt dual-frequency transducer purpose-built for recreational and serious anglers who demand reliable fishfinding performance in shallow to moderate depths. This 8-pin transducer combines temperature sensing with removable speed assembly in a rugged plastic housing designed for transom mounting on boats ranging from center consoles to bay boats.

Operating at 50 kHz and 200 kHz, the 525ST-PWC delivers 45-degree and 11-degree beam angles respectively—a proven frequency pairing that balances wide coverage for structure location with narrow-beam detail for precise target identification. The 600-watt output provides sufficient power penetration for bottom tracking and fish detection in depths up to roughly 1,500 feet, though performance excels in the 50- to 500-foot range where most recreational fishing occurs. The integrated temperature sensor delivers real-time water data, while the removable speed assembly allows quick disconnection without exposing the connector to elements.

This transducer suits weekend anglers targeting inshore structure and serious offshore fishermen who need secondary sounder capability. The 30-foot cable with 8-pin connector integrates with Furuno chartplotters and standalone fish finders across the manufacturer's compatible models. Plastic housing resists impact from dock lines and gear contact while remaining lighter than stainless alternatives—a practical consideration for boats with mid-range weight distribution or retrofit installations.

The Furuno 525ST-PWC represents straightforward transducer engineering: no digital processing, no built-in GPS, just reliable dual-frequency fishfinding at a price point that makes upgrading older single-frequency systems cost-effective.
