Lowrance HDI Transom Transducer — Med/High CHIRP & DownScan 455/800 kHz | 000-12570-001

Lowrance HDI Transom Transducer — 000-12570-001

The Lowrance 000-12570-001 HDI Transom Transducer delivers four sonar frequencies from a single transom-mount unit: Med CHIRP and High CHIRP for traditional depth and fish arch readings, plus DownScan Imaging at 455 kHz and 800 kHz for detailed structure and bottom composition views. HDI — Hybrid Dual Imaging — combines standard CHIRP sonar with DownScan Imaging in one transducer body, eliminating the need to install separate transducers for each sonar type.

Mounted on the transom with a standard bracket, this transducer suits a wide range of powerboats and is compatible with Lowrance fishfinder and chartplotter displays using the 9-pin xSonic connector. For anglers who prefer a skimmer-style transducer with similar CHIRP and DownScan capability, see the Lowrance Hook² Splitshot Skimmer Transducer — 000-14028-001.

Best Use Case

The right transducer for powerboat anglers who want both traditional CHIRP sonar and DownScan Imaging from a single transom-mount installation. The four-frequency range — Med CHIRP for deeper water coverage, High CHIRP for sharper shallow-water detail, 455 kHz DownScan for wider structure views, and 800 kHz DownScan for high-resolution close-range imaging — makes this a capable all-round transducer for freshwater and inshore saltwater fishing.

Key Features

• HDI (Hybrid Dual Imaging): CHIRP sonar + DownScan Imaging in one transducer

• Transom-bracket mount — standard installation on most powerboat transoms
• 9-pin xSonic connector for compatibility with current Lowrance displays
• Suited to freshwater and inshore saltwater use

Parts Desk Insights

• Best use case: Powerboat anglers wanting CHIRP depth sonar and DownScan Imaging from one transom-mount transducer — the four-frequency range covers both deep-water and shallow-water scenarios without swapping transducers
• HDI explained: HDI combines traditional CHIRP sonar (for fish arches and depth) with DownScan Imaging (for structure, vegetation, and bottom detail) — both views available simultaneously on compatible Lowrance displays
• Prefer a skimmer mount? The Lowrance Hook² Splitshot Skimmer Transducer — 000-14028-001 offers CHIRP and DownScan in a skimmer form factor for boats where a transom bracket isn’t ideal
• Need SideScan too? The Lowrance Hook² TripleShot Skimmer Transducer — 000-14029-001 adds SideScan Imaging alongside CHIRP and DownScan in a skimmer mount
• Connector compatibility: 9-pin xSonic — if your Lowrance display uses a 7-pin port, you’ll need the Lowrance xSonic 9-Pin to 7-Pin Adapter Cable — 000-13977-001
