Key Technologies That Redefine Marine Radar Performance

MotionScope Doppler Processing for Real-Time Threat Detection

Leveraging Doppler effect principles, MotionScope instantly identifies objects moving toward or away from your vessel, coloring them green for approaching threats and red for receding ones. This visual cue helps you sidestep collisions in busy harbors or track erratic weather cells forming offshore. Unlike traditional radars that leave you guessing, this feature provides immediate situational awareness, proven invaluable during night passages or in zero-visibility scenarios.

Pulse Compression: Sharp Imaging Without Compromise

Pulse Compression maximizes energy output for superior short- and long-range detection while delivering high-definition resolution. You'll see crisp separation between small buoys and larger ships, or distinguish individual birds in a flock from clutter. This tech ensures weak echoes—like distant debris—aren't lost in noise, giving you a reliable picture from 20 feet to horizon-spanning 96 nautical miles.

True Echo Trails for Intuitive Target Tracking

Watch moving targets leave fading "echo trails" on your chartplotter, automatically adjusted for your boat's motion when paired with a heading sensor or autopilot. This makes it effortless to gauge speed and direction, spotting potential close-quarters risks before they become problems.

Tailored Features for Every Boating Scenario

• Auto Bird Gain: Spot surface-feeding birds that betray schools of baitfish below—perfect for sportfishermen chasing trophies.
• Dynamic Auto Gain and Sea Clutter Filters: Automatically tunes to waves and weather, with customizable low/medium/high settings for calm bays or stormy seas.
• Dual Range Overlay: Split-screen radar on your Garmin chartplotter with independent scales; overlay both on charts for hybrid views that reveal near threats and far horizons simultaneously.
• MARPA Tracking: Monitor up to 10 targets with mini-automatic radar plotting aid, calculating closest point of approach to prevent mishaps.
• Guard Zones and Alarms: Define safe perimeters around your boat; get audible alerts if anything intrudes.

Versatility with Dual Radar Support and Easy Customization

Pair it with a second radar for backup redundancy across multiple displays. Adjust target sizing to declutter screens or sharpen coastlines, tweak rotation speeds (up to 48 RPM for rapid updates), and use VRM/EBL tools for precise range and bearing measurements. It's all intuitive—no steep learning curve.
