Lowrance TM 20° Skimmer® Transducer Product Description
Unlock Crystal-Clear Underwater Views with the Lowrance HST-WSU Transducer
Imagine gliding across the water, your fishfinder painting a precise picture of what's lurking below. The Lowrance HST-WSU transom mount skimmer transducer delivers exactly that—reliable 200kHz sonar performance with a focused 20-degree beam angle, perfect for anglers chasing structure and fish in shallower waters. Built tough for real-world boating, this transducer doesn't just detect; it reveals details that help you hook more catches.
With an integrated temperature sensor, you'll track water conditions alongside depth readings, giving you the edge in understanding fish behavior. The included 20-foot cable with a Uni-Plug connector simplifies setup, ensuring seamless integration with your existing Lowrance display.
Standout Features for Everyday Angling Success
- Precise 20-Degree Beam: Ideal for detailed scanning in depths up to 700 feet, excelling in rivers, lakes, and coastal zones where tight focus matters.
- 200kHz Frequency: Balances resolution and coverage, cutting through clutter to highlight fish arches, bottom contours, and wrecks.
- Built-In Temp Sensor: Monitors surface water temperature in real-time, helping you locate thermoclines and bait schools.
- Skimmer Design: Low-profile transom mount stays submerged at speed, minimizing air bubbles for consistent readings even at trolling or planing speeds.
- Rugged Construction: Impact-resistant housing withstands the rigors of saltwater and freshwater environments.
Seamless Compatibility Across Lowrance Models
This transducer pairs effortlessly with a wide range of trusted Lowrance units, breathing new life into older setups or enhancing newer ones. It's a go-to upgrade for:
- Cuda series: 128, 128 P, 168, 168 EX, 242, 250 S/Map, 300, 350
- FishEasy lineup: 240, 245 DS, 250 DS, 320
- FishElite models: 500C, 502C iGPS, 640C, 642C iGPS

Whether you're running a compact portable or a full-featured chartplotter, this plug-and-play design gets you back on the water fast.
Effortless Installation Tips for Peak Performance
Mounting is straightforward for DIY boaters. Position the transducer about 1/3 of the hull length from the transom, parallel to the waterline at rest. Deadrise angle adjustment ensures the face stays perpendicular to the bottom for accurate readings. Secure with stainless hardware, route the cable away from electrical noise sources, and test at various speeds. Pro tip: Apply marine sealant around mounting holes to prevent leaks, and periodically check for marine growth that could dampen signals.
Real-World Performance That Delivers Results
Anglers rave about its sensitivity in spotting suspended fish and subtle bottom changes—think weed edges or drop-offs that hold walleye or bass. The narrow beam rejects off-axis interference, providing cleaner screens on choppy days. Pair it with your Lowrance unit for enhanced 2D sonar that rivals modern high-end systems, all without breaking the bank on replacements.
Long-Lasting Reliability and Maintenance Essentials
Engineered for durability, the HST-WSU shrugs off dings from docks and trailer impacts. Clean the face monthly with a soft brush and freshwater rinse to maintain peak transmit power. In saltwater, flush with a descaler solution seasonally. Store dry during off-seasons to avoid corrosion—simple habits that extend its lifespan for seasons of reliable service.
Frequently Asked Questions
What depths does the Lowrance HST-WSU transducer handle best?
It shines in shallow to moderate depths up to around 700 feet, thanks to the 200kHz frequency and 20-degree beam, making it perfect for inland lakes, rivers, and inshore fishing.
Does this transducer work at high boat speeds?
Yes, the skimmer design keeps it submerged and stable up to planing speeds, delivering consistent sonar returns without excessive ventilation.
Is the temperature sensor accurate for fishing insights?
Absolutely— it provides reliable surface water temp readings, crucial for targeting species like stripers or crappie that key on thermal breaks.
How do I know if this fits my Lowrance fishfinder?
Check your model against the compatibility list; the Uni-Plug connector matches most legacy Lowrance ports directly.
Can I install this transducer myself?
Most boat owners can—basic tools and following transom alignment guidelines get it done in under an hour.
What's the cable length included?
A generous 20 feet provides ample reach from transom to helm without extensions.
Does it work in both fresh and saltwater?
Yes, its robust build handles both environments with proper rinsing to combat salt buildup.
