This unit is highly recommended as a critical safety enhancement for serious boaters.
Know before you buy
The 60 RPM rotation provides an almost real-time update of your surroundings at ranges up to 1.5 nautical miles. This high-speed refresh rate is critical for collision avoidance, as it allows you to track fast-moving targets with much greater precision than standard radar units.
Yes, the HALO20+ features Dual Range mode, which allows you to monitor two different ranges simultaneously. This lets you keep an eye on distant weather patterns while maintaining a close-up view of potential collision hazards near your vessel.
VelocityTrack™ automatically color-codes targets based on whether they are moving toward or away from your boat. This instant visual feedback helps you quickly identify and prioritize potential collision threats without needing to manually track every object on the screen.
Yes, the HALO20+ is designed to operate on both 12V and 24V DC systems. It has a wide input voltage range of 10.5V to 31.2V, making it versatile for most mid-sized to large sailboats.
No, the HALO20+ features an instant wake from standby mode. Unlike traditional pulse radars that require time to warm up, this unit provides immediate situational awareness the moment you need it.
The unit is built to a high standard with an IPX6 water-resistance rating and is designed to operate in temperatures ranging from -25°C to +55°C (-13°F to +130°F). It is engineered to perform reliably in the harsh, exposed conditions typically found on a sailboat deck.
