Raymarine i40 Bidata Display System with Thru-Hull Transducers - E70145

Raymarine i40 Bidata Display System with Thru-Hull Transducers – E70145

The Raymarine i40 Bidata Display System (E70145) delivers critical depth and speed information in a sleek, easy-to-read instrument package designed for both sailboats and powerboats. This complete system combines a dedicated i40 Bidata display with high-quality thru-hull depth and speed/temperature transducers to provide accurate real-time readings for depth, speed through water, and water temperature—all from a single, compact interface.

Featuring a high-contrast, sunlight-readable LCD with red backlighting, the i40 Bidata display ensures excellent visibility in all lighting conditions on deck. With native SeaTalkng connectivity and backward compatibility with NMEA 2000 networks, this system integrates seamlessly into your Raymarine instrument network or can function as a standalone instrument set.

The thru-hull transducers included in this system deliver reliable underwater sensing for depth, speed, and temperature, helping you navigate safely and efficiently. Designed to match legacy ST60+ instrument footprints, the Raymarine i40 Bidata Display System installs easily and provides accurate, dependable performance that enhances situational awareness on every voyage.

i40 SeaTalk Instruments - Bidata w/Thru-Hull Transducer

Compact and feature-packed instruments, the i40 series instruments are smart choice for boaters looking high performance and great value.

The i40 series is simple to operate thanks to the use of just three control buttons, i40 has extra-large digits and razor-sharp LCD displays and red backlighting for outstanding visibility in all lighting conditions.

These SeaTalk compatible instruments offer full integration with Raymarine autopilots and navigation equipment. The ultra-sleek design of i40 line is designed to complement our full line of a-Series, c-Series and e-Series Multifunction displays, and looks great on the helm of any boat. All i40 Instruments come with a low-profile surface mounting kit and silicone rubber sun cover. An optional bracket mounting kit is also available separately.

i40 Instruments are designed to operate from 12V DC power, and are ultra-efficient drawing less than 0.4 watts for superior run-time and excellent green credentials. The i40 instruments are all covered by Raymarine's industry leading 2-year warranty, upgradeable to 3-years at no charge by registering online with 90 days of purchase.

i40 Bidata Instrument
The Raymarine i40 Bidata offers all of the functionality of the Depth and Speed instruments combined in a single space-saving display. Like the other i40 Instruments, the Bidata is available as a complete system with depth and speed transducers or as a display-only solution for remote readout of depth and speed at another location.

The i40 Bidata's depth capabilities include easy-to-read displays of current speed, maximum speed, average speed, distance log, trip log as well as water temperature. Bidata also offers depth-related alarms and adjustments including shallow depth alarm, deep depth alarm, shallow anchor alarm, and deep anchor alarm, and depth offset controls. Its speed capabilities include displays of current speed, maximum speed, average speed, distance log, trip log as well as water temperature.
