<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 BT70MA600-12 is a low-profile bronze thru-hull transducer engineered for high-performance marine fishfinding and depth sounding applications. This medium frequency CHIRP transducer operates across the 80-130 kHz range, delivering exceptional bottom detail and fish targeting capabilities for professional and sport fishing vessels.

Key Features:

  • Medium frequency CHIRP technology (80-130 kHz) for superior target separation and bottom imaging
  • 600-watt power rating for strong signal penetration in various water conditions
  • 12-degree tilted element design optimized for hulls with 8-15 degree deadrise angles
  • Low-profile bronze housing provides excellent durability and corrosion resistance in saltwater environments
  • Thru-hull mounting ensures clean hydrodynamics and optimal signal transmission
  • Compatible with Si-Tex Echonautics CHIRP-enabled fishfinders and chartplotters

The tilted element configuration allows the transducer to be properly aligned with the water flow regardless of hull angle, ensuring accurate depth readings and clear bottom composition data. Bronze construction makes this transducer ideal for saltwater applications where long-term reliability is essential. The medium frequency CHIRP range provides an excellent balance between depth capability and target resolution, making it versatile for both shallow and moderately deep water fishing.

First order experience was great. Received the day after I ordered. I ordered the very same item on Jul 21st, got a shipping notification and tracking number but the item appears to be stalled somewhere. I need it sooner rather than later. I have spoken with customer service via telephone call and online chat, but not getting much of a response from either. Appreciate someone looking into it as I need this item quickly. Thanks, Tim.

Best price around and fast shipping. Parts came undamaged and ready to install. Thanks!
