Raymarine Wireless Speed & Depth System with Triducer — Product description

Imagine gliding through choppy waters with instant access to your boat's speed, depth, and water temperature—no tangled wires or bulky consoles holding you back. This wireless speed and depth system transforms how sailors navigate, delivering real-time data that's crisp, reliable, and tailored for performance. Perfect for competitive racers or casual cruisers, it harnesses cutting-edge wireless tech to keep your focus on the horizon, not the helm clutter.

Effortless Data at Your Fingertips

The heart of this setup is its intuitive multifunction display, which lets you customize two lines of live info simultaneously. Whether you're tracking boat speed through water, plotting depth changes around shoals, or monitoring temp shifts for optimal sail trim, everything updates wirelessly without a hitch. Sailors rave about how it cuts through distractions during tacks and gybes, giving you that edge in tight races or foggy approaches.

Hull Transmitter: Your Central Hub

Mounted discreetly near your transducers, this compact transmitter gathers speed, depth, and temp signals, then beams them across the deck via a robust wireless link. Its low-profile design slips into tight spaces, resisting corrosion from saltwater spray. No more drilling holes for cables—just plug in your sensors, power it up, and watch your network come alive. It's engineered for boats where every ounce counts, minimizing drag while maximizing uptime.

Triducer Powerhouse: Triple-Threat Sensing

The star sensor here combines speed, depth, and temperature in one streamlined package, shooting precise readings through the hull with minimal turbulence. Unlike clunky through-hull setups, it provides log-free speed data that's spot-on even in currents, helping you fine-tune your VMG. Temp readings alert you to thermoclines that could affect your genoa shape, turning raw numbers into winning tactics.

Why Wireless Wins on the Water

Ditching cables means faster installs and easier upgrades—ideal for retrofitting older yachts or prepping a new race boat. The system's low-power wireless protocol ensures data flows uninterrupted up to 20 meters, even around masts and rigging. Battery life stretches through entire seasons with standard cells, and it's fully expandable to wind, compass, or GPS modules for a full tactical suite. Real-world sailors report zero dropouts in 25-knot puffs, proving its grit where competitors falter.

Simple Setup for Serious Results

Getting started takes under an hour: Position the triducer below the waterline (avoid propeller turbulence), connect to the hull transmitter with short leads, and pair the display via a quick button sequence. Calibrate for your hull type once, and it's locked in. No IT degree required—just sailor smarts. Pro tip: Angle the display forward for glare-free reads under peak sun, and you'll wonder how you ever sailed without it.

Elevate Your Sailing Game

From coastal hops to offshore legs, this system arms you with data that feels alive, not afterthought. Racers use it to nail laylines; cruisers rely on it for safe anchoring. It's not just instruments—it's your silent crew, whispering secrets of wind, wave, and water to sharpen every decision.

Frequently Asked Questions

Does this speed and depth system work completely wirelessly?

Yes, the display receives data wirelessly from the hull transmitter, eliminating deck cables. Transducers connect to the transmitter via short wired leads for reliability.

How long do the batteries last in this wireless sailing system?

Batteries in the display and transmitter are designed for low-drain operation, often lasting an entire sailing season or more with routine checks, depending on usage.

Can I expand this system with other sensors?

Absolutely—it's part of a modular wireless network compatible with wind, compass, and heading sensors, building a full race suite without extra wiring.

Is installation DIY-friendly for average sailors?

Yes, most setups take 30-60 minutes with basic tools. Fair the triducer hole properly, secure the transmitter dry, and auto-pairing handles the rest.

What boats is this best suited for?

Ideal for keelboats, racers, and dinghies from 20-50 feet where cable-free precision matters. It shines in performance sailing but works great for day cruising too.

Does the triducer measure water temperature?

Yes, it provides accurate temp readings alongside speed and depth, helping with sail trim and spotting current boundaries.

How accurate is the speed readout in varied conditions?

Paddlewheel-free design delivers true speed-through-water within 0.1 knots, compensating for leeway and heel for reliable polars.

Is it resistant to harsh marine environments?

Built tough with IPX7 waterproofing and UV-stable materials, it handles spray, submersion, and years of sun exposure without fading.
