Humminbird XTH 9 DB 74 Bronze Thru-Hull Transducer

The Humminbird XTH 9 DB 74 Bronze Thru-Hull Transducer is for large boats, and boats with in-board motors that make most typical transducers ineffective. This bronze thru-hull transducer is not recommended for trailered boats, and Humminbird recommends you have it professionally installed due to the fact that it requires a hole be drilled in the hull and the shaping of a fairing block. The XTH 9 DB 74 is a dual-beam transducer with 20-, and 74-degree beam angles and operating frequencies of 200 kHz and 50 kHz. This unit measures 2.75 x 5.25 inches (W x H), with a 1.25-inch below-hull depth and a shaft diameter of 0.81 inches. The Humminbird XTH 9 DB 74 comes with a 30-foot connecting cable and all the necessary mounting hardware, but does not include a fairing block. The XTH 9 DB 74 is for use with Humminbird's 931C DF and 937C DF sonar systems, and is backed by Humminbird's one-year limited warranty.
