Lowrance HST-DFSBL Dual Frequency Transom Transducer
The Lowrance HST-DFSBL is a dual-frequency transom-mount transducer built for reliable depth and fish detection across a wide range of water conditions. The dual-frequency design lets you switch between a narrower, deeper-penetrating beam and a wider, shallower beam — giving you flexibility to adapt your sonar to the depth and structure you’re fishing.
The stainless steel construction and blue connector (BL) make this a durable, long-lasting transducer suited for regular use in both fresh and salt water environments.
Key Features
- Dual-frequency sonar for versatile depth and fish detection
- Transom-mount installation
- Stainless steel construction for durability in fresh and salt water
- Blue connector (BL) for compatibility with matching Lowrance display inputs
- Compact and lightweight — 227g
Best Use Cases
- Versatile freshwater and inshore fishing — Dual frequency lets you adapt between deeper, narrower coverage and shallower, wider coverage depending on conditions
- Anglers needing a reliable transom-mount traditional sonar transducer — A straightforward, durable option for depth and fish finding without imaging

Parts Desk Insights
Best use case: Recommend the HST-DFSBL to customers who need a reliable dual-frequency transom transducer for traditional sonar — depth and fish finding — without imaging capability. It’s a good fit as a replacement transducer for compatible Lowrance displays using the blue (BL) connector. Always confirm the customer’s display uses the blue connector standard before recommending. If the customer wants to add DownScan or SideScan Imaging, direct them to the DownScan Skimmer (000-10976-001) or the Active Imaging™ 3-in-1 (000-14489-001) instead. For longer cable runs, pair with the XT-12BL or XT-20BL extension cables.
