The Raymarine i40 Speed Display System with Transom Mount Transducer is an essential instrument for serious anglers and cruising boaters who demand reliable, real-time speed data. Whether you're navigating coastal flats, offshore waters, or inland lakes, knowing your precise water speed helps optimize fuel efficiency, improve casting accuracy in shallow water, and maintain safe operation in varying sea states.

This compact display system integrates seamlessly into modern helm setups, providing critical speed information for both performance and safety on the water. Raymarine's engineering focuses the i40 on straightforward functionality and durability in saltwater and freshwater environments. The transom-mount transducer design minimizes through-hull drilling and installation complexity, making retrofit projects manageable for most boat owners.

Boaters upgrading aging analog speedometers or adding speed capability to older vessels benefit most from this system's straightforward installation and reliability. The display unit itself measures 7 by 4 inches, fitting neatly into standard dash openings or console spaces without consuming excessive real estate. The transom-mount transducer works across both power and sailboat applications, ensuring versatility for various boating needs.
