Lowrance TripleShot Skimmer Transom-Mount Transducer 3-in-1

The Lowrance TripleShot Skimmer Transom-Mount Transducer is the 3-in-1 transducer that gives you traditional CHIRP sonar plus SideScan and DownScan imaging from one transducer body, mounted on the boat's transom (no through-hull required). For boats that want the full Lowrance imaging feature set without the cost or installation complexity of a separate dedicated imaging transducer, the TripleShot is the right answer.

What "3-in-1" means here. Three independent sonar functions running simultaneously through the same transducer body, each producing its own data stream that the connected fish finder displays as a separate sonar window. The 200 kHz traditional CHIRP sonar (the wide 40-degree beam) provides classic vertical fish-and-structure detection - the screen you've used on every fish finder for the past 30 years, modernized with CHIRP signal processing for better target separation. The 455 kHz SideScan imaging (and the higher-resolution 800 kHz mode) projects narrow beams horizontally to the sides of the boat, mapping the bottom and any structure / fish in those zones into a photo-like image that scrolls as the boat moves forward. The 455 / 800 kHz DownScan imaging projects narrow beams straight down, generating a high-resolution top-down view of what's directly under the boat - meaningfully sharper than traditional sonar for picking out structure detail and fish hugging the bottom. Three views, one transducer.

200 kHz wide-beam High CHIRP. The 40-degree beam angle is meaningfully wider than the typical 20-degree narrow CHIRP transducer beam. The wider beam covers roughly double the bottom area at any given depth, so a slow troll across a structure piece insonifies more of the structure per pass - faster fish-finding workflow than narrow-beam transducers. The High CHIRP signal processing (sweeping a frequency band rather than transmitting a single frequency) gives meaningfully better target separation - two fish stacked vertically a foot apart show as two distinct returns instead of merging into one fuzzy blob. The combination of wide beam + CHIRP processing is the right traditional sonar setup for the recreational fisherman who wants to find fish quickly across a wide search area.

500-foot CHIRP depth, 300-foot imaging depth. The traditional CHIRP sonar reaches roughly 500 feet of bottom depth in clear water with reasonable bottom hardness - enough for offshore fishing in continental shelf depths, lake fishing in any inland water body, and coastal fishing in any nearshore application. The SideScan and DownScan imaging modes work to roughly 300 feet of effective depth - the imaging modes use higher frequencies (455 / 800 kHz) which give the resolution needed for photo-like images, and those higher frequencies don't penetrate as deep as the lower 200 kHz CHIRP frequency. For boats that fish primarily in 0-300 foot waters, both the CHIRP and imaging functions cover the depth range fully. For boats that fish deeper than 300 feet, the CHIRP function still provides traditional sonar to 500 feet, while the imaging modes lose effectiveness past their 300-foot rating.

SideScan imaging - photo-like side views. SideScan is the imaging modality that meaningfully changed recreational fish finding in the last 15 years. The narrow horizontal beams paint a photo-like image of the bottom and any structure / fish to the sides of the boat - typically out to roughly 250 feet on each side at the right altitude / depth combination. Run a slow troll along a flat, and the SideScan image scrolls back to show every rock pile, weed bed, log, brush pile, and fish-holding feature on either side of the boat track. Mark a waypoint on a piece of structure that shows up on SideScan, then come back to that exact spot for a focused fishing approach. The workflow is meaningfully faster and more thorough than traditional sonar for identifying productive structure across a wide area.

DownScan imaging - sharp top-down views. DownScan is the high-frequency, narrow-beam, straight-down imaging mode. Unlike traditional sonar (which integrates across the full beam width and shows a single bottom return profile), DownScan generates a sharp, high-resolution image of what's directly under the boat - individual rocks, individual fish, the boat's wake bubbles, the lure on a vertical jig drop. For boats that troll over structure, the DownScan view tells you exactly where the structure is and exactly where the fish are relative to it. For vertical jigging applications, DownScan lets you watch the lure descent and the fish reaction in real time.

Built-in water temperature sensor. The transducer body includes a water temperature sensor that reports surface water temperature to the connected fish finder. Water temperature is a meaningful variable for fishing strategy (different species are active in different temperature ranges, thermoclines are findable by temperature gradient changes, etc.) and the integrated sensor means you don't need a separate temperature transducer hanging off the transom.

Compatible Lowrance fish finders. The TripleShot connects via Lowrance's standard 9-pin transducer connector to fish finders that support TripleShot 3-in-1 functionality. The compatibility list includes HDS LIVE (all sizes), HDS Carbon (all sizes), Elite FS (all sizes), Elite Ti2 (all sizes - some specific revisions), and HOOK Reveal (specific TripleShot variants). Check the specific fish finder model's transducer compatibility chart - some fish finder models support traditional CHIRP only (not the imaging modes), in which case the TripleShot still works but the imaging modes don't display. The full 3-in-1 functionality requires a fish finder with both CHIRP and SideScan / DownScan support.

Transom mount installation. The TripleShot mounts on the boat's transom (the vertical face at the back of the boat) using the included mounting bracket and stainless steel hardware. The skimmer-style mount sits flush against the transom when the boat is at rest, and the kick-up bracket allows the transducer to flip up if it strikes an underwater object (saves the transducer from being torn off by impact). Install location: typically on the starboard side of the transom, below the boat's typical waterline at running speed, away from the prop wash zone (the prop wash creates aerated water that confuses the sonar return). The included install instructions detail the typical mount location and angle.

What's in the box. The TripleShot transducer with attached cable (typically 20 feet, sufficient for most transom-to-helm cable runs on small-to-medium boats), the transom mounting bracket and kick-up hardware, stainless steel mounting screws, and the install template for marking the mounting hole locations on the transom.

Install. Mark the mount holes using the included template, drill the holes (use marine sealant in the holes before installing screws to prevent water intrusion into the transom core), bolt the bracket to the transom, slide the transducer into the bracket and secure with the bracket's locking pin. Route the cable through a transom cable gland (sold separately) into the boat's interior and run to the fish finder location. Plug the transducer cable into the fish finder's 9-pin transducer port. Total install time is typically 2-4 hours for a competent boat owner with reasonable mechanical skill and the right tools (drill, marine sealant, transom cable gland).
