Simrad HALO20+ 36 NM 20-in Pulse Compression Radar - Fast Collision

In this review the Simrad HALO20+ is evaluated as a compact but capable marine radar aimed at boaters who need fast, reliable hazard detection without a large antenna. The biggest reason to consider the HALO20+ is its near real-time situational awareness enabled by ultra-fast 60 RPM operation and built-in VelocityTrack Doppler processing, which together make it easier to identify and respond to potential collisions while still keeping long-range coverage up to 36 NM.

Key Features

• 60 RPM operation: The ultra-fast scan rate delivers an almost real-time view at close range so small, fast-moving targets are clearer for collision avoidance.
• VelocityTrack Doppler: Built-in Doppler technology highlights moving targets to help you quickly distinguish hazards from stationary clutter in busy waterways.
• Dual Range capability: Simultaneous short and long-range coverage lets you monitor nearby traffic and distant weather or contacts at the same time.
• Pulse compression technology: Advanced pulse compression with beam sharpening improves target definition without requiring a larger dome.
• Compact 20-in dome: The 20 in antenna keeps the unit compact and suitable for a wide range of vessels while still reaching up to 36 nautical miles.

Who It's For

The HALO20+ is best for coastal cruisers, sportfishers, and commercial operators who need fast target updates and collision awareness from a compact dome. Its strengths are most useful in crowded channels, close-quarters maneuvering, and for vessels that also need long-range detection for weather or shore contacts.

Smaller dayboat owners who rarely venture beyond a few miles and sailors on minimalist electronic budgets may find the HALO20+ more capability than they need; similarly, operators requiring specialized phased-array features or larger range performance might prefer larger systems.

Pros & Cons

Pros

• Excellent close-range visibility from 60 RPM scanning for faster reaction to nearby traffic.
• VelocityTrack Doppler makes moving contacts stand out, improving decision-making in cluttered conditions.
• Simultaneous dual range lets users keep an eye on near hazards and distant weather at once.
• Pulse compression and beam sharpening give clearer target definition from a compact 20 in dome.

Cons

• Advanced features increase system complexity and may require time to learn optimal setup and interpretation.
• The unit may be more capability than needed for casual boaters who rarely face dense traffic or low-visibility conditions.

Frequently Asked Questions

Does the HALO20+ show moving targets distinctly?
Yes. The built-in VelocityTrack Doppler processing highlights moving contacts to make them easier to identify against stationary clutter.

Can it monitor near and far contacts at the same time?
Yes. The HALO20+ supports simultaneous dual-range operation so users can view short and long ranges concurrently.

Is the antenna large?
No. It uses a compact 20 in dome while still providing coverage up to 36 NM thanks to pulse compression and beam sharpening.
