Simrad HALO20 20" Radar Dome w/10M Cable
Simrad HALO20 20" Radar Dome w/10M Cable — Product description
Picture this: you're out on the water at dusk, fog rolling in, and traffic picking up around the marina. That's when a reliable marine radar like the Simrad HALO20 becomes your best ally. This compact 20-inch dome radar punches way above its weight, blending cutting-edge pulse compression tech with an ultra-low profile design perfect for smaller vessels. Boaters rave about its ability to spot hazards from mere feet away out to 24 nautical miles, all without the bulk or power drain of older systems.
What sets the HALO20 apart isn't just the specs—it's how it transforms everyday boating into safer, stress-free adventures. Whether you're a weekend angler dodging crab pots or a coastal cruiser weaving through channels, this radar delivers crystal-clear images that cut through rain, waves, and clutter like a hot knife through butter.
Unlock Superior Situational Awareness on the Water
The HALO20 excels in tight spots where traditional radars falter. Its pulse compression technology sends out precise, efficient pulses that provide unmatched short-range resolution—think detecting a small buoy or swimmer just 50 meters ahead. No more guessing games in harbors or during fish-finding runs.
Collision avoidance gets a serious upgrade with MARPA (Mini-Automatic Radar Plotting Aid) target tracking. Lock onto up to 10 targets (or 20 in dual-range mode) and watch their course, speed, and closest point of approach in real-time. Pair it with guard zones, and you'll get audible alerts for any intruders in your safe bubble. It's like having an extra set of eyes scanning 360 degrees.
- InstantOn™ wakes from standby in seconds—no waiting minutes for a cold start.
- Radiation-safe operation keeps your crew protected during family outings.
- Low power draw (just 18-20W typical) means it plays nice with battery banks on dayboats.
Why Pulse Compression Changes the Game for Small Boats
Unlike old-school magnetron radars that guzzle power and warm up slowly, pulse compression uses solid-state magic to pack more punch into less energy. The HALO20's 10W output rivals bulkier units, offering a 4.9° horizontal beam width for sharp target separation. Vertical beam is 25°, ideal for picking out low-profile objects like half-submerged logs.
Switch between tailored modes—Harbour for cluttered docks, Offshore for open water, Weather for rain-squashed returns—and you'll see targets pop vividly. North Up, Course Up, Relative, or True Motion displays adapt to your style, integrating seamlessly with Simrad multifunction displays for overlay on charts.
Pro tip: For best results in choppy conditions, tweak gain and sea clutter manually after auto-tuning. This radar rewards a little hands-on adjustment, revealing details that generic settings miss.
Real-World Scenarios Where HALO20 Shines
Fishing Trips: Spot bird flocks, rip lines, or wrecks from afar, then zoom in on pots and debris close aboard without false echoes.
Night or Fog Navigation: 24 RPM rotation speed (yes, even in wind up to 100 knots) ensures fresh data every 2.5 seconds, critical when visibility drops to zero.
Weekend Cruising: Compact 20" diameter x 8.8" height footprint mounts easily on T-tops or arches, leaving room for rods and coolers.
Many owners pair it with Simrad NSS or NSO series for a full fishfinder-radar-GPS suite, creating a command center that feels pro-grade without the pro price tag.

Effortless Installation and Maintenance Tips
Mounting is straightforward: Secure to a flat surface with minimal clearance (check for 510mm diameter space). The included 10m cable reaches most helm stations; use weatherproof glands for deck passes. Connect via Ethernet to your Simrad MFD—no extra power supply needed beyond a 5A fuse.
For longevity, rinse with fresh water after saltwater exposure, and store in a dry spot off-season. Solid-state design means no magnetron to replace, slashing maintenance headaches. Expect reliable performance backed by a limited 2-year warranty.
Frequently Asked Questions
What makes the Simrad HALO20 ideal for small boats?
Its compact 20-inch dome, low power use, and instant start-up suit sportfishers and dayboats perfectly, offering 24 NM range without draining batteries or crowding the deck.
How does MARPA work on the HALO20 radar?
MARPA tracks up to 10 targets (20 in dual range), calculating speed, course, and collision risk. Select a target on your display, and it overlays vectors for easy monitoring.
Is the HALO20 radar safe for use around people?
Yes, it's radiation-safe with low emissions, unlike older pulse radars. You can operate it confidently near crew or passengers.
What's the startup time for this radar?
Thanks to InstantOn™, it powers up in seconds from standby—even from full power-down—far quicker than traditional radars that take minutes.
Can the HALO20 handle bad weather?
Absolutely. Weather mode optimizes for rain clutter, IPX6 sealing withstands heavy spray, and it spins reliably in 100-knot winds.
Does it integrate with other Simrad gear?
Seamlessly via Ethernet to Simrad MFDs like NSS or NSO evo3 series, enabling radar overlays on charts, sonar, and autopilot.
How do I maintain the HALO20 dome?
Rinse with fresh water post-use, avoid abrasive cleaners, and ensure good ventilation. No internal parts to service—solid-state reliability.
