The Simrad HALO 20+ Pulse Compression Dome Radar brings next‑level situational awareness to your helm with an almost real‑time view and industry‑leading speed. Housed in a compact 20‑inch dome, HALO 20+ delivers a complete 360° picture at up to 60 RPM nearshore and offshore, giving you rapid, reliable awareness of nearby traffic, buoys, and potential hazards.

Why HALO 20+ changes the game

VelocityTrack Doppler technology instantly highlights moving targets, helping you differentiate between stationary obstacles and heading vessels. The radar’s pulse compression design preserves target detail at close range while maintaining robust long‑range detection, so you can identify hazards in cluttered channels and busy harbors without sacrificing resolution.

• 60 RPM high‑speed rotation for almost real‑time updates at short range, with a 36 nautical miles long‑range capability from a single, low‑profile dome.
• Dual range, no compromise—seamlessly monitor near objects and distant targets in one sweep.
• Instant On solid‑state transmitter (no magnetron) for quick startup and reliable performance in challenging conditions.
• Low power, high efficiency operating 17–29W (typical) at 13.8V with standby around 3.9W, ideal for power‑sensitive vessel systems.

Built for real‑world navigation

Whether you’re threading through a crowded marina, navigating in fog, or skimming a busy coastal route, HALO 20+ keeps a clear picture with beam sharpening and selectable target separation controls. Its rugged build withstands demanding marine environments—from icy dawns to hot, humid afternoons—with an operating range that spans 6 m to 36 nm, 18 configurable ranges, and a vertical beam that provides solid target detection even in sea clutter.

Durability and reliability you can trust

Designed for marine use, HALO 20+ meets stringent standards with IPX6 waterproofing, operating temperatures from <-25°C to +55°C>, and high wind tolerance up to 100 knots. The compact, lightweight package (20" dome, about 5.9 kg) simplifies installation on a wide range of vessels, from smaller sport cruisers to heavier center consoles.

What this means in everyday use

• Safer passagem in busy waterways thanks to rapid updates and Doppler colouring that clearly marks approaching vessels and potential collision risks.
• Better decision making with real‑time awareness and dual‑range coverage—you won’t miss short‑range hazards while still tracking distant traffic.
• Efficiency and reliability with a solid‑state transmitter, low power consumption, and fast startup—ready when you are.
