<h3>About SI-TEX Marine Electronics</h3><p><strong>SI-TEX Marine Electronics</strong> has been a trusted name on the water for over 50 years, building a reputation among commercial captains, charter operators, sportfishermen, and serious recreational boaters for delivering rugged, reliable, and straightforward marine electronics. Founded in 1975 and headquartered in Riverhead, New York, SI-TEX has remained committed to a single mission throughout its history: provide mariners with the features they actually need, the durability they expect, and the value they appreciate.</p><p>What sets SI-TEX apart from larger, more corporate brands is the depth of experience behind every product. President Ted Bodtmann has been shaping marine electronics since 1967, and the leadership team collectively brings decades of hands-on industry knowledge to product design and customer support. That institutional knowledge translates directly into electronics that work the way seasoned mariners expect them to — straightforwardly, dependably, and without unnecessary complexity.</p><h3>A Full Spectrum of Marine Electronics</h3><p>SI-TEX offers one of the most complete lineups in the marine electronics segment. Their product catalog spans professional-grade <a href="/11288-si-tex-simrad-radars-autopilots-200957">radar systems and autopilots</a>, high-performance echo sounders and CHIRP sonar, precision GPS navigation and chartplotting systems, heading sensors, VHF communications, AIS transponders, and more. Whether you&apos;re outfitting a hardworking commercial vessel, a sportfishing yacht, an inshore skiff, or a long-range cruiser, there is an SI-TEX solution engineered for the task.</p><p>Their SVS Series chartplotter/sounder combos — including the SVS-880 and SVS-760 — are especially popular with commercial fishermen and smaller vessel operators, offering high-resolution color displays, powerful sonar capabilities, and intuitive operation in a compact, rugged package. The NavPro series takes things further, pairing large touchscreen MFDs with built-in Wi-Fi radar compatibility, CHIRP sonar, and Navionics or C-MAP charting integration. For vessel control, the SP-120 autopilot series supports hydraulic, mechanical, and dash-drive steering systems across a range of vessel sizes, and even offers virtual feedback to eliminate the need for a rudder sensor on some installations.</p><p>SI-TEX also offers a comprehensive range of accessories and connectivity hardware — including <a href="/11288-si-tex-diagnostic-scan-tool-cable-18035">cable adapters and interface solutions</a> — designed to keep their electronics integrated and upgradeable as technology evolves. These accessories make it easier to expand an existing SI-TEX system or transition between product generations without starting from scratch.</p><h3>Backed by a 2-Year Warranty and U.S.-Based Support</h3><p>Every SI-TEX product is backed by a <strong>2-Year Warranty</strong> and supported by an experienced service team based in Long Island, New York. For mariners who spend serious time on the water, that combination of product durability and accessible support is not a minor detail — it&apos;s a core reason professionals keep coming back to the brand. SI-TEX also distributes Koden products to the commercial marine market, extending their reach to even more demanding commercial and offshore applications.</p><p>From a single transducer cable to a fully integrated radar, chartplotter, and autopilot system, SI-TEX delivers the tools serious mariners rely on — built tough, priced fairly, and backed by people who know the sea.</p>

Product Details

The Si-Tex BT87H1KW-12 is a high-performance bronze thru-hull CHIRP transducer designed for serious anglers and boaters who demand accurate depth and temperature readings. This low-profile transducer features a 12-degree tilted element optimized for deadrise angles between 8 and 15 degrees, ensuring optimal sonar performance on a wide range of hull configurations.

Key Features:

  • 1000-watt high-frequency CHIRP technology operating at 130-210 kHz for exceptional target separation and clarity
  • Bronze housing construction for superior durability and corrosion resistance in saltwater environments
  • Low-profile design minimizes drag and reduces turbulence
  • 12-degree tilted element for proper acoustic alignment on 8-15 degree deadrise hulls
  • Narrow beamwidth ranging from 13 to 8 degrees at -3 dB for precise bottom tracking
  • Maximum depth capability of 1000 feet
  • Integrated temperature sensor for accurate water temperature monitoring
  • 30-foot cable with Echonautics connector included
  • Compact dimensions: 4.8 inches diameter x 5.2 inches height
  • Requires 3.45-inch diameter hole for installation

This transducer delivers the power and precision needed for deep-water fishing and navigation, with CHIRP technology providing superior target definition compared to traditional single-frequency transducers. The bronze construction ensures long-term reliability in harsh marine conditions.

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.

As described and rapid delivery.

Good, No issues.

I needed a small blaster, y'all had it, I ordered it, and then I received it, price was ok, but the shipping price was cheap I thought, thanks
