Humminbird XTH-9-20-P Plastic Thru Hull Transducer

Plastic Thru Hull TransducerPlastic Thru-Hull Transducers are for large boats and for boats with in-board motors that make typical Transom Mount Transducers ineffective. They are not recommended for trailered boats as the transducer is not flush with the hull. Plastic Thru-Hull Transducers require that a hole be drilled in the hull and the shaping of a fairing block. Professional installation is recommended. Bronze Thru-Hull Transducers are an alternative to Plastic Thru-Hull Transducers.Description: Single/Dual Beam, 20/60 Degree, 200/83 kHz transducer. 3.9"L X 2.5"W X 1.16"D.
