Echonautics BT70D600CW-12 600w 50/200kHz 12d Tilted Element Bronze TH

The Echonautics BT70D600CW-12 600w 50/200kHz 12-degree tilted element bronze thru-hull transducer is engineered for anglers and boaters who demand reliable target definition in shallow water combined with solid deep-water bottom tracking. This dual-frequency transducer addresses the core challenge every serious angler faces: balancing high-resolution sonar performance in shallows without sacrificing depth capability or target separation in open water. Whether you're working ledges, drop-offs, or structure at depth, this transducer delivers the versatility required for mixed-water fishing and cruising.

The 50/200kHz frequency split—50kHz for deep-water penetration and 200kHz for shallow-water detail—gives you superior sonar separation across the entire water column. The 12-degree tilted element design minimizes cone overlap and improves bottom tracking consistency, particularly valuable when operating at speed or in challenging bottom compositions. Bronze thru-hull construction resists corrosion in saltwater environments and provides superior structural integrity compared to plastic alternatives. At 600 watts of power output, this transducer generates strong return signals for crisp fish arches, baitfish clouds, and subtle structure detail—critical for identifying productive holding zones in variable conditions.

This transducer is optimized for anglers running moderate-to-high speeds who need sonar performance without excessive drag penalty. The streamlined bronze housing is designed for minimal water resistance, making it ideal for center-console boats, cruisers, and performance-oriented fishing platforms. Installation requires a thru-hull mounting location with proper deadrise compensation—the 12-degree tilt element accommodates most hull angles found on modern recreational and fishing vessels. Compatible with Echonautics chartplotters and multifunction displays that support dual-frequency sonar, the BT70D600CW-12 integrates seamlessly into existing marine electronics systems.
