The Proven Standard

Reliable, rugged, and versatile. The Humminbird XNT 9 20 T is the classic "Skimmer" style transom transducer that has powered Humminbird units for over a decade. Whether you are replacing a broken transducer on an older unit or adding a high-speed depth source to a new one, this is the part you need.

Dual Beam Precision:

Capable of 200 kHz (Narrow Beam) for bottom detail and 83 kHz (Wide Beam) for fish arches, it covers all the basics perfectly. It features a built-in temperature sensor and the improved "kick-up" bracket to prevent damage from impact.

Frequently Asked Questions

Will this work on my Side Imaging unit?

It will provide 2D Sonar and Depth only. It cannot produce Side Imaging or Down Imaging pictures. However, many anglers use this transducer alongside their big SI transducer (connected via a 9 M SIDBY Y-Cable) to maintain reliable depth readings while running at high speeds on plane.

Is this better than the XNT 9 HW T?

Not necessarily "better," just different. The XNT 9 HW T is the newer "High Wide CHIRP" transducer found on G3/G4 models. The XNT 9 20 T (this one) is the standard Dual Beam (83/200) transducer. If you have an older unit (G1/G2 or 800/900/1100 series), this XNT 9 20 T is usually the correct factory replacement.

My old transducer looks identical but has no temp. Is this the right one?

Yes. The older XNT 9 20 (without the "T") did not have a temperature sensor. This newer version (XNT 9 20 T) includes the temp sensor built-in, but it fits and functions exactly the same on your unit—you just get the bonus of seeing water temp now!
