Raymarine i40 Bidata Display System

The Raymarine i40 Bidata Display System is a compact marine instrument designed to deliver critical performance data directly to your helm. Built for boaters who demand high visibility and intuitive operation without unnecessary complexity, this SeaTalk-compatible display integrates seamlessly with Raymarine autopilots and navigation systems to provide real-time speed, depth, and water temperature readings. The i40's three-button interface and large LCD digits make it accessible to both weekend anglers and offshore cruisers operating in variable lighting conditions.

At 7 x 3 x 10 inches and weighing just 1.8 lbs, the i40 occupies minimal panel space while delivering maximum readability. The red backlighting cuts through bright sunlight on the water, and the razor-sharp LCD display maintains clarity at varying viewing angles—critical when navigating tight channels or monitoring depth in variable bottom conditions. The compact footprint makes it ideal for smaller boats and retrofit installations where real estate is limited, yet the display provides the dual-parameter bidata output serious boaters need for navigation and fishing decisions.

This display is engineered for boaters who rely on accurate, immediate instrument feedback—whether running coastal routes, anchoring in shallow water, or tracking water conditions for species location. SeaTalk integration means the i40 connects directly to compatible Raymarine transducers and autopilot systems without requiring additional interface modules. The simple three-button operation reduces the learning curve, allowing crew members of all experience levels to quickly interpret speed and depth data. The i40 Bidata Display represents Raymarine's balance of compact design, essential functionality, and field-proven reliability in a system sized right for modern fishing and cruising vessels.
