Perfect for coastal bay and fishing boats, Lowrance's HALO20+ Boat Radar delivers high-quality short, mid and long-range detection up to 36 nautical miles away. The Lowrance radar performs a full 360 degree sweep every second, owing to its industry-first 60 RPM rotation at distances of up to 1.5 nautical miles. These ultra-fast updates provide you with an almost real-time view at close range, helping you avoid collisions with fast moving targets.

HALO20+'s Dual Range mode lets you keep an eye on distant weather cells, while looking for any closer collision hazards. In addition, pulse compression technology ensures no compromises in detection at either range, with beam sharpening providing improved separation between small or distant targets.

Built-in VelocityTrack technology provides instant visual feedback on whether targets are approaching you or moving further away. Potential hazards are colour coded, improving your situational awareness and reducing your risk of collision. The boat 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.
