Raymarine i50 Depth Display System w/Thru-Hull Transducer

The Raymarine i50 Depth Display System is a specialized, high-reliability instrument built for one job: providing clear, instantaneous depth data. It ditches the complexity of multi-function displays for a large-format monochrome LCD featuring 1.1-inch digits that are readable from across the cockpit, even in direct midday sun.

### The Strengths
The i50 shines in its uncompromising visibility and ease of integration. With SeaTalk$^\text{ng}$ and NMEA 2000 compatibility, it drops into modern networks as easily as it replaces legacy ST60+ units. Users rely on its user-configurable alarms for shallow and deep water, which provide essential peace of mind when navigating tricky channels. The included P319 thru-hull transducer offers a low-profile fit that minimizes drag while maintaining a consistent signal.

### The Trade-offs
The primary drawback is its single-function nature; you aren't getting speed or wind data on this screen. The monochrome segmented display also feels dated compared to full-color IPS screens, and the thru-hull installation requires a permanent 2-inch hole in your hull, which may be a dealbreaker for some DIYers.

### The Verdict
While you could spend more on a color multi-instrument, the i50 is a "buy" for the serious navigator who wants a dedicated, fail-safe depth read-out that doesn't require menu-diving. Its low power consumption and bulletproof reliability far outweigh the lack of aesthetic "flair," making it a cost-effective essential for any helm where visibility is the top priority.
