Raymarine i40 Depth Display System w/Transom Mount Transducer

The Raymarine i40 Depth Display System with transom mount transducer delivers real-time water depth information in a compact, high-visibility instrument designed for recreational and serious anglers alike. This depth finder combines straightforward operation with marine-grade reliability, making it an effective solution for both freshwater and saltwater boaters who need accurate bottom readings without complex integration.

The i40 series instruments feature an extra-large LCD display with red backlighting, engineered for visibility across variable lighting conditions—critical when running early morning or dusk fishing operations. Three-button control keeps the learning curve minimal, allowing operators to focus on fishing rather than interface navigation. The included transom mount transducer installs directly on the boat's hull, transmitting sonar signals that calculate depth with the accuracy needed for structure fishing and safe water navigation. SeaTalk compatibility enables integration with other Raymarine marine electronics, supporting expansion as your boat's system grows.

This depth display suits anglers transitioning from basic instruments to integrated marine systems, as well as boat owners managing compact console space where a dedicated depth instrument provides essential information without requiring full multifunction display real estate. Weekend fishermen benefit from the simplified operation, while serious offshore anglers value the SeaTalk networking capability for coordinating depth data across integrated helm stations.

The transom mount transducer location minimizes installation complexity and reduces wiring requirements compared to in-hull alternatives, making the i40 a practical upgrade path for boats without existing sonar infrastructure. At 4.4 lbs and compact dimensions (10 x 4 x 14 inches), the display head installs cleanly on dashboards or bulkheads without requiring significant mounting modifications.
