Furuno 235DST-MSE Bronze Thru-Hull, Digital Depth, Speed & Temp Sensor - 7-Pin

Discover Reliable Marine Sensing with the Furuno 235DST-MSE

Navigating the open water demands precision, and the Furuno 235DST-MSE delivers just that through its robust bronze thru-hull design. This digital sensor combines depth measurement, speed-through-water tracking, and high-precision temperature readings in one compact unit, helping boaters make informed decisions whether trolling for fish, charting unfamiliar waters, or simply enjoying a sunset cruise. Built on decades of Furuno's engineering expertise, it stands out for its durability in harsh marine environments, ensuring consistent performance season after season.

Standout Features That Enhance Your Boating Experience

• Bronze Construction for Lasting Durability: Crafted from high-quality bronze, this thru-hull sensor resists corrosion from saltwater exposure, making it ideal for offshore adventures and long-term reliability.
• Triple Functionality: Seamlessly measures water depth for safe navigation, calculates boat speed through water (unaffected by currents or wind), and provides temperature data with pinpoint accuracy of +/-1°F—perfect for targeting species that prefer specific thermal zones.
• 235 kHz Frequency at 200 Watts: Optimized for clear, detailed bottom contours and fish arches from shallow coastal areas up to moderate depths, balancing resolution and power without overwhelming noise.
• Versatile Mounting: Flush-mounts easily on hulls with deadrise angles up to 22 degrees, accommodating a wide range of vessels from planing hulls to deeper V-shapes.
• Extended Reach: Comes with a 32.8-foot (10-meter) cable and 7-pin connector for flexible routing to your display unit, minimizing signal loss over distance.
• Airmar-Inspired Housing: Modeled after the proven B17 style, it offers a streamlined profile that reduces drag while maintaining excellent acoustic performance.

Why This Sensor Excels in Real-World Conditions

Boaters know that inconsistent data can lead to missed opportunities or risky decisions. The 235DST-MSE's digital output transmits cleaner signals compared to older analog models, reducing interference and providing faster updates on your chartplotter or fishfinder. Imagine gliding through foggy inlets with real-time depth alerts, adjusting speed to match conditions, or marking spots where water temps spike—drawing big game closer to your line. Its thru-hull placement delivers the most direct path to bottom data, outperforming transom-mount alternatives in rough seas where hull slap might skew readings.

For weekend warriors or seasoned captains, this sensor simplifies setup without sacrificing pro-level insights. Pair it with your existing electronics for a cohesive system that feels intuitive from day one.

Practical Tips for Optimal Performance

To get the most from your Furuno 235DST-MSE, consider hull preparation: a smooth, fair surface around the mounting hole ensures bubble-free operation and maximum signal clarity. In variable conditions, rely on its speed data to fine-tune trolling patterns or log precise trip stats. Regular hull cleaning keeps the bronze faceplate pristine, preserving sensitivity over time. This sensor thrives in diverse scenarios, from freshwater lakes to salty bays, proving its worth across boating lifestyles.
