Like other Garmin radar, the GMR 24 processes signals within the radome via a digital signal processor to reduce noise and improve sensitivity. This is dynamically presented on a Garmin Marine Network compatible chartplotter/multifunction display (MFD). Digital processing allows for more precise recognition, enhancement, and filtering of radar echoes, making the finished display easier to read and interpret.

The unit supports a number of features when paired with the appropriate Garmin MFD, including:

MARPA (Mini Automatic Radar Plotting Aid) collision avoidance capability, which allows boaters to track the course, speed and predicted closest approach (by both time and distance) of multiple targets.

Chart overlay capability, allowing boaters to reconcile radar signatures with known objects on the chartplotter

Split the screen between standard radar presentations and radar overlay

Suitable for boats of 32ft upwards, the GMR 24 features sensitivity and tuning controls, including gain, sea clutter, and rain clutter, which allows users to spend less time tuning the unit and more time navigating. The unit also boasts selectable interference rejection, which mitigates the effect of nearby radar transmissions. The GMR 24 communicates with the Garmin Marine  Network through a waterproof 100 megabit per second plug and play proprietary network, which affords users the ability to expand their boat’s system as needed. A Marine Network cable connector kit is also included for customizing installation.
