Raymarine i40 Depth Display System w/Thru-Hull Transducer

The Raymarine i40 Depth Display System w/Thru-Hull Transducer is a standalone depth sounder designed for anglers and cruising boaters who require accurate bottom readings without the need for integration into a larger chartplotter system. This device is perfect for verifying water depth before anchoring or locating fish in various water conditions.

Featuring a dedicated 4-inch LCD display, the system pairs with a high-frequency thru-hull transducer that operates in dual-frequency modes, providing both narrow and wide beam sonar for detailed bottom mapping. The transducer is designed to be mounted below the waterline, ensuring reliable communication through a hardwired connection, which helps maintain a clean installation without the clutter of traditional cable runs.

Ideal for center console, walkaround, and cruising boats ranging from 22 to 55 feet, this system serves as a dedicated depth instrument that enhances your primary navigation suite or functions independently. Its adjustable sensitivity and zoom features allow users to customize their view of water depth and substrate hardness, making it a valuable tool for both fishing and navigation.
