Raymarine i40 Depth Sounder Pack with P66 Transducer (E26027-PZ)

The Raymarine i40 depth sounder pack, integrating the depth instrument and the P66 flush-mount transducer, is a pragmatic solution for vessels requiring dedicated and reliable depth data display. Its practical value is clear for small sailboats and powerboats, day-boats, or as a backup instrument on larger units. It provides instant and continuous depth readings without navigating complex menus, unlike multifunction displays (MFDs) that may group this information among many others.

Installation is relatively straightforward, particularly thanks to the P66 flush-mount transducer which avoids complex hull drilling typically associated with through-hull transducers. SeaTalk 1 and SeaTalk NG connectivity is a major asset; it enables easy integration into existing onboard networks, whether old or new-generation Raymarine systems. This means depth data can be efficiently shared with an autopilot, chartplotter, or other instruments without requiring additional converters for SeaTalk NG systems. However, for fully NMEA 2000 installations without other Raymarine equipment, an STNG-to-NMEA 2000 converter may be necessary if the instrument must feed a broader network.

This model differs from MFDs by its single-task function and compact format. It is ideal for those prioritizing the clarity and simplicity of a dedicated instrument. It will not suit users seeking advanced cartography, CHIRP sonar, or side-scanning functions, which are reserved for higher-end MFDs like the Raymarine Axiom series. The i40 depth sounder is a relevant choice for upgrading from analog instruments or outfitting a small unit, offering a robust and proven solution with marine-grade durability for constant visibility of critical depth information.
