Lowrance HALO20 20" Radar Dome w/5M Cable Product Description
Unmatched Visibility from Close Quarters to Horizon
Picture this: you're maneuvering through a foggy inlet or scanning for markers at dusk. The Lowrance HALO20 radar dome changes the game with its pulse compression technology, blending razor-sharp short-range clarity—down to just 50 meters—with impressive reach up to 24 nautical miles. Unlike older magnetron systems that struggle with clutter near the boat, this 20-inch dome paints a clean image, highlighting buoys, smaller vessels, and debris without the noise.
Boaters rave about its ability to pick up targets others miss, making it a go-to for trailered boats or compact cruisers where space is premium. The narrow 4.9-degree horizontal beamwidth ensures you spot what's ahead precisely, reducing guesswork during those critical moments.
Proactive Collision Avoidance and Situational Mastery
Safety isn't reactive—it's about staying steps ahead. The HALO20's MARPA (Mini-Automatic Radar Plotting Aid) tracks up to 10 targets at once, or doubles to 20 in dual-range mode, calculating course, speed, and closest point of approach. Set guard zones to get alerts on potential threats, whether it's a drifting log in busy channels or approaching traffic at night.
For coastal anglers or weekend warriors, this means more confidence in low-visibility ops, like heavy rain or dawn patrols. It's radiation-safe too, so no worries about crew exposure during family outings.
Power Up in Seconds, Not Minutes
Forget the long warm-ups of traditional radars that drain batteries while you wait. HALO20's InstantOn™ tech springs to life from standby in under a second, or from full power-off in moments. Low power draw—typically 18W—keeps your 12/24V system happy, ideal for extended trips without constant generator runs.
Switch effortlessly between optimized modes: Harbour for cluttered marinas, Offshore for open water, Weather to pierce rain squalls, or custom tweaks for your style. At 24 RPM rotation, updates are fluid and responsive, with North/Course Up and relative/true motion views adapting to your needs.
Ideal for Everyday Boating Adventures
Whether you're chasing reefs, navigating locks, or just enjoying sunset cruises, HALO20 fits seamlessly. Its rugged IPX6 waterproofing and -25°C to +55°C operating range handle harsh marine environments, shrugging off 100-knot winds. Compact at 510mm diameter and 5.9kg, mounting is straightforward on most arches or masts.
Real-world tip: Pair it with your chartplotter for overlay views, turning raw data into intuitive navigation. Anglers love the short-range detail for spotting bird piles over bait balls, while cruisers appreciate the clutter-free long-range scan.

Frequently Asked Questions
What makes pulse compression technology in the HALO20 better for boating?
Pulse compression delivers high-resolution images at both short and long ranges without the bulk or warm-up time of traditional radars, minimizing clutter for clearer detection of nearby obstacles and distant targets.
How does InstantOn™ work on this radar?
It activates radar coverage almost immediately from standby or power-off, unlike conventional systems that take minutes to heat up, ensuring you're covered without delay.
What is MARPA target tracking and how many targets can it handle?
MARPA automatically tracks targets' speed, course, and collision risk. The HALO20 monitors up to 10 targets standard, or 20 in dual-range mode for enhanced monitoring.
Is the HALO20 suitable for harsh weather conditions?
Yes, with IPX6 waterproofing, operation from -25°C to +55°C, and tolerance for 100-knot winds, plus dedicated Weather mode to cut through rain clutter.
What's the power draw like for battery-powered boats?
It sips power at 18W typical (20W max) on 12/24V systems, with a 5A fuse recommendation, perfect for efficient all-day use.
How compact is the HALO20 dome for installation?
Measuring 20 inches in diameter and 8.8 inches high at just 13 lbs, it's designed for easy mounting on most vessels without dominating the silhouette.
