Dive into the Technology
Down Imaging (DI): See What's Truly Below
The core feature of the XNT 9 DI T is its powerful Down Imaging capability. This technology operates at a high frequency (455 kHz), directing a razor-thin sonar beam downward. The resulting returns create incredibly detailed, picture-like images of structure, vegetation, and fish. With Down Imaging, you can:
- Distinguish Fish from Structure: Clearly see individual fish holding tight to submerged logs, brush piles, and rock ledges.
- Identify Bottom Composition: Easily tell the difference between a hard, rocky bottom and a soft, muddy one.
- Eliminate Guesswork: Move beyond traditional 2D sonar "blobs" and see a recognizable representation of the underwater landscape.
DualBeam PLUS: The Power of Two Beams in One
Complementing the advanced Down Imaging is Humminbird’s reliable DualBeam PLUS 2D sonar. This technology gives you the classic fish-finding view with enhanced clarity and coverage by utilizing two separate sonar beams:
- Narrow Beam (200 kHz): This focused beam provides high-detail returns, excellent for pinpointing fish and structure directly under the boat and determining bottom composition.
- Wide Beam (455 kHz): This beam offers a much larger coverage area, perfect for searching for fish in the surrounding water column.
You can view each beam separately or combine them for a comprehensive picture that balances detail with expansive coverage.
Primary Compatible Models & Usage
The XNT 9 DI T is the factory-supplied, standard transducer for a wide range of popular Humminbird HELIX models that feature Down Imaging but not Side Imaging. Its "9" designation specifically aligns it with the HELIX 5 and HELIX 7 series. If you own one of the following units, this is the correct replacement transducer to maintain original performance.
Used as Standard Equipment On:
-
HELIX 5 Series:
- HELIX 5 DI
- HELIX 5 DI G2
- HELIX 5 CHIRP DI GPS G2
- HELIX 5 CHIRP DI GPS G2N
-
HELIX 7 Series:
- HELIX 7 DI
- HELIX 7 DI GPS
- HELIX 7 DI G2
- HELIX 7 DI G2N
- HELIX 7 CHIRP DI GPS G2
- HELIX 7 CHIRP DI GPS G2N
-
PiranhaMAX Series:
- PiranhaMAX 4 DI
- PiranhaMAX 197c DI
Important Compatibility Note: This transducer is NOT for Side Imaging (SI) or MEGA Imaging models. It does not contain the necessary crystals or technology to produce Side Imaging views. Attempting to use this on an SI or MSI unit will result in limited or non-functional sonar performance. Always match the transducer to the specific capabilities of your fish finder head unit.
