Lowrance HALO24 Radar Dome w/Doppler Technology [000-14541-001]

HALO24 Radar Dome with Doppler Technology

Elevate your marine navigation with the Lowrance HALO24 Radar Dome, a compact yet powerful radar system built for both recreational and serious boaters. Featuring integrated VelocityTrack™ Doppler technology and simultaneous short- and long-range operation, this dome radar gives you enhanced situational awareness, collision avoidance, and storm detection—all in one low-profile package.

Key Features & Capabilities

• Up to 48 Nautical Mile Range — Detect objects and weather patterns far beyond the horizon from a compact 24-inch dome. 
• VelocityTrack™ Doppler Technology — Automatically color-codes moving targets based on their relative motion (approaching or moving away) to help you identify collision risks instantly. 
• Simultaneous Dual Range Operation — View both near-range and long-range targets at the same time without sacrificing clarity or performance. 
• Ultra-Fast Update Rate (60 RPM at Close Range) — Experience almost real-time scanning with full 360° sweeps per second in close range mode, ideal for tight navigation zones or heavy traffic areas. 
• Advanced Pulse Compression & Beam Sharpening — Maintain excellent target resolution and separation even in cluttered environments.
• Built to Withstand Harsh Environments — Rugged, low-profile 24″ dome with integrated LED indicator lights. Waterproof and built to meet marine standards.Quick “Instant-On” Startup — From standby to full operational mode in seconds, saving you from waiting for warm-up. 
• MARPA Target Tracking — Track up to 10 targets (20 in dual-range mode) to monitor movement of surrounding vessels and hazards. 
• Flexible Compatibility — Integrates with Lowrance multifunction displays (MFDs) via Ethernet and supports standard marine system wiring.
