Simrad Halo 20+ Radar with 10m cable

Simrad Halo 20+ Radar with 10m cable

£2,041.99 RRP: £2,479.99
Pulse compression radar with 20 inch dome antenna, 36nm range
Simrad’s Halo Radar will keep constant watch over you and your crew. Whether you’re racing offshore or blue water cruising in severe conditions, through fog, iceberg fields or at night, you’ll be glad of the Simrad HALO Radar range; receive a crystal clear image, right up to the bow of your boat. The new HALO pulse-compression radars provide the ultimate in target detection and high levels of safety with unbelievable clarity for both long and short range views simultaneously.

*Halo20/20+ Radars safe distances based on conservative approach after measurement by Navico, and applying a further safety factor. These numbers will be updated upon completion of measurements by independent laboratory.
Simrad Halo 20+ Radar
Simrad Halo 20+ delivers an almost real-time view, with industry-leading 60 RPM operation at close range for the ultimate in collision avoidance. Pinpoint hazards in an instant with VelocityTrack Doppler technology, and enjoy simultaneous short and long-range coverage—up to 36 nautical miles—from a compact 20-inch dome antenna.

See Near and Far with One Lightweight, Compact Dome
Ideal for a wide range of smaller sailboats, Simrad Halo 20+ comes in a compact dome antenna and delivers high-quality short, mid and long range detection. Sailors can monitor two distance ranges at once in Dual Range mode allowing them to keep an eye on distant weather cells, while watching for collision hazards nearby. Simrad Halo 20+ radar’s pulse compression technology means no compromises in detection at either selected range, while beam sharpening provides enhanced separation between small or distant targets.

The Ultimate View for Collision Avoidance
Simrad Halo 20+ delivers a full 360-degree sweep every second, thanks to its industry-first 60 RPM rotation at ranges up to 1.5 nautical miles. These ultra-fast updates give sailors an almost real-time view at close range – offering the ultimate view for collision avoidance of fast-moving targets.

VelocityTrack Doppler Technology Built-In
With Simrad Halo 20+, sailors can identify hazards quickly with VelocityTrack Doppler technology, which delivers instant feedback on whether targets are coming toward you or moving away. Simple colour coding highlights potential hazards, improving situational awareness and further reducing the risk of a collision. Simrad Halo 20+ radar automatically checks every target in range, so there’s no need to manually select individual targets, and no limit to the number of targets on screen at one time.

Ready When You Are
Simrad Halo 20+ Radar wakes instantly from its low-power standby mode, delivering this high-speed radar coverage exactly when and where you need it. Even if your Simrad Halo 20+ Radar is completely powered down start-up is a matter of seconds, not minutes like traditional pulse radar. Whether you’re navigating through crowded waterways or contending with poor visibility, Simrad Halo 20+ Radar immediately cuts through the clutter to give you a clear and current picture of your surroundings.

Easy to Use
Harbour, Offshore, Weather, Bird, and custom modes tune Simrad Halo 20+ Radar’s advanced signal processing to help ensure that targets can be seen vividly – even in the toughest environmental conditions.
