Lowrance TotalScan Skimmer Transom Mount Transducer

The Lowrance TotalScan Skimmer Transom Mount Transducer (part 000-12568-001) is the all-in-one transom transducer that consolidates CHIRP sonar plus StructureScan HD side imaging plus DownScan Imaging plus temperature into a single transom-mounted unit. The xSonic 9-pin black connector with the 24-foot cable, the standard skimmer foot for transom mounting, and full compatibility with the Lowrance HDS Gen3, Elite-7 Ti, and Elite-5 Ti displays. One transducer, three sonar views, no compromises.

What this transducer actually delivers. CHIRP sonar at 83 kHz and 200 kHz medium and high CHIRP frequencies for traditional 2D fish-arch and bottom imagery, the same sonar return you've been using for years to find fish marks and read bottom hardness. StructureScan HD at 455 kHz and 800 kHz for high-resolution side-scan imagery that throws photo-quality returns out to either side of the boat for finding structure on a search pass. DownScan Imaging at the same StructureScan frequencies for the photo-quality straight-down view of what's directly under the boat. Three sonar views, one transducer, no separate transom installs needed for each function.

The xSonic 9-pin black connector is the modern Lowrance transducer standard. The 9-pin connector replaces the older 7-pin blue connector and adds the additional pins needed to carry the StructureScan HD signals. If you have a current-generation Lowrance display (HDS Gen3, Elite-7 Ti, Elite-5 Ti, and newer HDS LIVE generations), the xSonic connector plugs in directly. The 24-foot cable length is the right length for the typical transom-to-helm wire run on most recreational boats, with enough slack to route cleanly along the gunwale into the dash.

If you have an older Lowrance display with a 7-pin blue connector, the TotalScan transducer can connect via a 7-pin xSonic adapter cable (sold separately). Note that on legacy 7-pin displays, the side-scanning feature won't function because the older connector doesn't have the additional pins for the StructureScan HD signals. Down imaging, CHIRP sonar, and temperature all still work. The full TotalScan capability requires a current xSonic-compatible display.

CHIRP sonar at 83 and 200 kHz is the right traditional sonar configuration for most freshwater and inshore saltwater fishing. The 200 kHz high-frequency channel gives you tight-target separation and detailed bottom return for fish identification, depth tracking, and bait-ball detection. The 83 kHz low-frequency channel gives you wider beam coverage for searching larger volumes of water and deeper bottom returns where the high frequency starts to lose signal. Medium CHIRP at 83 kHz and high CHIRP at 200 kHz both supported, which gives you the modulated-frequency sweep that improves target separation over the older single-frequency sonars.

StructureScan HD side imaging at 455 and 800 kHz is the feature that changed how serious anglers fish. Press a button and a photo-quality picture appears showing the bottom out to either side of the boat, typically 100 to 200 feet of coverage on each side at typical search depths. Find a brush pile, a hump, a road bed, a piece of structure, a school of bait, you mark the GPS position, and you go back and fish it. The 800 kHz frequency gives the highest detail at shorter ranges. The 455 kHz frequency reaches out further. The TotalScan supports both.

DownScan Imaging is the photo-quality straight-down view at the same StructureScan frequencies. While CHIRP sonar gives you the traditional fish-arch presentation, DownScan gives you the photo of what's directly under the boat. Brush, timber, weed lines, vertical structure, suspended baitfish columns, all become recognizable shapes instead of CHIRP-arch interpretations. Run CHIRP and DownScan side by side on a split screen and you get the best of both presentations.

Temperature sensing is built into the transducer (no separate temp sensor needed). The temp reading shows up on the display alongside depth and is the single most useful piece of data for finding feeding fish: most species have preferred temperature ranges and the boundaries between water masses are where the bait and the fish concentrate. If you weren't already running temp on your old transducer, you'll wonder how you fished without it.

The skimmer foot is the standard transom-mount foot designed to ride above water at planing speeds and stay in the water at idle and trolling speeds. Multiple mounting positions allow tuning of the transducer angle for boats with different transom rake angles. The skimmer foot kicks up if it strikes a submerged object, protecting the transducer from impact damage. Stainless mounting hardware included.

What this transducer isn't. It is not a thru-hull transducer (use a Lowrance thru-hull for cruising sailboats and displacement powerboats that need flush bottom flow). It is not the Active Imaging 3-in-1 (which is a newer-generation Lowrance transducer with similar capability and a different connector layout). It is not a forward-facing sonar transducer like the LiveSight (LiveSight requires the dedicated transducer and a compatible display).
