SIMRAD HALO20 Marine Radar — 24 NM Range in a Compact 20-Inch Dome

The HALO20 from Simrad brings capable radar performance to smaller boats without the footprint or price of larger systems. Designed for budget-conscious buyers with sportfishing vessels and dayboats, this compact radar delivers a clear, current picture of obstacles and targets up to 24 nautical miles away. Its low-profile profile and small footprint mean you can install it where space is at a premium, while still gaining powerful situational awareness on the water.

Why HALO20 stands out

• 24 nm range with a compact 20-inch dome. Pulse-compression technology blends strong short-range detection with extended reach, providing reliable target definition while minimizing clutter in busy waterways.
• MARPA target tracking (up to 10 targets). Monitor multiple potential collision hazards and track their predicted paths for proactive decision-making.
• InstantOn and low power consumption. Wakes quickly from standby and sustains efficient operation, so you’re ready when you need it without draining the battery.
• Three optimized modes for real-world conditions. Harbour, Offshore and Weather modes tailor signal processing to your environment, helping targets stand out in fog, rain, or crowded harbors.
• Low-profile, easy integration. A compact dome with a thoughtful design fits into tighter spaces while delivering comprehensive radar coverage.
• Radiation safe and reliable. Built to meet maritime safety expectations while delivering dependable performance at sea.
• Guard Zones. Define boundary alerts to help you stay aware of restricted areas, shallow waters, or watchful creeks, enhancing on-water safety.

What problems HALO20 solves on the water

For skippers navigating crowded channels, variable visibility, or coastal weather, HALO20 provides a focused, pragmatic radar solution. It helps you detect collision risks early, identify boats and obstacles around you, and maintain safe clearance when maneuvering at speed or in tight spaces. The combination of short-to-mid-range clarity and MARPA target tracking makes it easier to plan safe courses and respond quickly to moving threats—all from a compact system suited for smaller boats.

Ideal use cases and who benefits most

Ideal for:

• Small sportfishing boats and dayboats seeking reliable radar without a large installation footprint.
• Operators who want fast, intuitive understanding of nearby traffic in harbor approaches, channels, and coastal waters.
• Boat owners who value proactive collision avoidance, clear target definition, and mode-specific tuning for different conditions.

Practical tips to maximize HALO20 performance

• Engage Harbour mode in busy harbors to reduce clutter and emphasize nearby vessels.
• Use Weather mode in mixed weather or rough seas to sharpen target visibility through adverse conditions.
• Leverage MARPA tracking to anticipate risk and plan safe passage routes, especially when other vessels’ courses cross yours.
• Enable Guard Zones to receive early alerts when approaching predefined risks or restricted areas.

With the HALO20, Simrad combines powerful radar capabilities with a compact, budget-friendly design. It’s a practical, reliable upgrade for safer, more confident time on the water, helping you detect hazards sooner, track multiple targets, and navigate with greater clarity—even when visibility is less than ideal.
