Imagine navigating choppy waters or cruising under a starry sky, with crystal-clear readings of your boat's speed, depth, log, and water temperature right at your fingertips. The Raymarine i40 Bidata steps in as your reliable onboard companion, packing dual data displays into a sleek, compact unit that's perfect for smaller vessels like powerboats, yachts, and RIBs. Unlike bulkier systems, this instrument shines by showing two metrics simultaneously—think speed over ground paired with depth—letting you stay focused on the horizon rather than squinting at multiple screens.

Standout Features That Elevate Your Boating Experience

This marine display isn't just about numbers; it's engineered for real-world reliability. Extra-large digits (up to 28mm) on a razor-sharp segmented LCD ensure readability from afar, even in glaring sunlight or pitch-black nights, thanks to the integrated red backlighting. Simple three-button controls keep operations intuitive, even with gloves on or waves rocking the boat.

• Dual Data Powerhouse: Seamlessly toggles between large and small digits for speed, depth, trip log, total log, and sea temperature—covering all essentials without clutter.
• Smart Alarms: Customizable alerts for shallow/deep water, anchor positions, and more, giving you peace of mind during anchoring or fishing.
• Network Savvy: Plugs into SeaTalk networks effortlessly, repeating data from other instruments or autopilots, or acting as a master with its own transducers.
• Energy Efficient: Sips just 35mA typical at 12V DC, extending battery life on long outings.
• Rugged Build: IPX6 waterproof rating shrugs off heavy sprays, with a tough design for harsh marine environments (-20°C to +55°C operation).

How the i40 Bidata Transforms Your Helm Setup

At its core, the Bidata combines depth and speed functionalities into one space-saving 3.5-inch display. Connect your own transducers directly via built-in ports, or let it pull data from the network for remote monitoring at the helm or companionway. Switch views effortlessly: monitor average speed for fuel efficiency, track trip logs for voyage planning, or watch water temp for fishing hot spots. Its low-profile surface mount (or optional trunnion) blends seamlessly with modern multifunction displays like Raymarine's a, c, or e-Series, creating a unified, professional look.

Pro Tip: Pair it with an autopilot for wind-referenced speed adjustments, ideal for sailors optimizing tacks or racers pushing limits.

Effortless Setup for Any Boater

Installation is straightforward, matching the footprint of older ST40 models for easy upgrades. Secure it with the included surface kit and silicone sun cover, route SeaTalk cables for power and data, and calibrate transducers in calm water for pinpoint accuracy. Dimensions (5.04" W x 2.83" H x 1.4" D) fit tight consoles perfectly. Network dimming syncs brightness across devices from one control point—no more mismatched glows at dusk.
