Enhance your boating experience with the Raymarine i40 Bidata Display System, a compact powerhouse that delivers essential speed, depth, and temperature readings in one sleek unit. Perfect for smaller vessels like powerboats, yachts, and RIBs, this instrument combines bold, easy-to-read digits with robust thru-hull transducers, ensuring you stay informed without cluttering your helm. Whether you're navigating shallow waters, tracking your trip log, or monitoring water temps for fishing, the i40 Bidata stands out for its reliability and seamless integration into any Raymarine ecosystem.

Why Boaters Trust the i40 Bidata for Precision Navigation

Imagine glancing at your helm and instantly seeing current speed over ground, depth below keel, and sea temperature—all without flipping between screens. The i40 Bidata's dual-line display features oversized 1.1-inch primary digits and crisp 0.5-inch secondary readouts, making data glanceable even in rough seas or low light. Its red backlighting kicks in automatically for night use, reducing eye strain during long passages. Unlike bulkier systems, this compact design (just 5 inches wide) fits neatly at chart tables, secondary stations, or main helms, saving space while packing pro-level features.

Boaters rave about its intuitive three-button operation—no steep learning curve here. Set customizable alarms for shallow water, deep anchors, or keel offsets to tailor alerts to your vessel's draft. Resettable logs track trip distance and max speeds, ideal for performance enthusiasts or casual cruisers logging adventures. As a repeater, it pulls data from networked SeaTalk devices, expanding your setup effortlessly.

Standout Performance in Real-World Conditions

• Versatile Data Display: Toggle between speed through water, log/trip, average speed, and depth with temp overlay—choose large digits for speed or depth priority.
• Smart Alarms: Shallow, deep, anchor, and minimum depth warnings keep you safe in unfamiliar anchorages or channels.
• Energy Efficient: Draws under 0.4 watts at 12V DC, perfect for battery-conscious setups on extended outings.
• Rugged Build: IPX6 waterproofing withstands spray, rain, and splashes, with a wide operating range from -4°F to 131°F.
• Future-Proof Networking: SeaTalk native, with easy upgrades to SeaTalk-ng or NMEA 2000 via converters for multifunction display compatibility.

Effortless Setup with Included Thru-Hull Transducers

The system arrives ready to install, complete with a 200kHz plastic thru-hull depth transducer for accurate bottom tracking and a separate low-profile speed/temperature thru-hull sensor. These flush-mount designs minimize drag, ideal for planing hulls. Built-in transducer ports simplify wiring—just connect and go. A low-profile surface mount cradle and silicone sun cover protect your investment, with optional bracket kits for flexibility. Low power draw ensures it plays nice with solar or limited battery systems.

Pro Tips for Maximizing Your i40 Bidata

Calibrate transducers post-install for hull-specific accuracy—adjust depth offset to match your keel. Pair with Raymarine autopilots for wind-referenced speed data, or expand to wind instruments for full sailing suites. For trailered boats, thru-hull sensors offer superior hull-readings over transom mounts in choppy conditions. Regular firmware checks via SeaTalk keep it cutting-edge.
