B60 Bronze Thru-Hull Transducer w/Humminbird #9 Plug - 7-Pin The bronze B60 provides a vertical beam without a fairing. Inside the housing, the ceramic element is tilted for built-in, deadrise compensation. The resulting vertical beam gives excellent echo returns for more-accurate depth readings. The nearly-flush housing minimizes drag with only 5 mm (3/16") extending outside of the hull.Features:Engineered for center-console and trailered boatsLow-profile protrusion below the hullNo affect on your boats running performanceArrow on cap points toward keel when installedBuilt-in temperature sensorBoat Size: Up to 8 m (25')Bronze transducer housing Specifications:Weight: 1.4 kg (3 lb)Hull Acoustic Window: Urethane
