Simrad HALO24 Radar Dome w/Doppler Technology

Discover Unmatched Safety and Awareness on the Water

Imagine threading through busy harbors or foggy inlets with confidence, spotting distant storms while tracking nearby vessels in real time. The Simrad HALO24 radar dome transforms your boating experience by blending compact design with cutting-edge performance. Ideal for sailboats, fishing rigs, and mid-sized powerboats, this 24-inch unit punches above its weight, offering clarity that larger systems envy without the bulk or power drain.

Real-Time Collision Avoidance at Your Fingertips

Nothing beats the edge in tight spots like marinas or shipping lanes. With its groundbreaking 60 RPM rotation speed up to 2 nautical miles, the HALO24 delivers a fresh 360-degree scan every second. This isn't just faster—it's a game-changer for dodging obstacles, cutting through rain clutter, and maintaining a live feed on your multifunction display. Boaters report it feels like having a vigilant crewmate always on watch, especially during dawn patrols or dusk returns when visibility drops.

VelocityTrack Doppler: Spot Threats Instantly

Traditional radars leave you guessing—is that blip closing in or drifting off? VelocityTrack changes that with Doppler magic. It scans every target automatically, color-coding inbound dangers in red and outbound in green. No fiddling with selections; up to dozens of contacts get flagged at once. This tech shines in high-traffic zones, helping you prioritize real risks like crossing ferries or erratic jet skis, boosting your peace of mind on family outings or solo adventures.

Dual Range Mode: Near and Far, No Compromises

Split your screen effortlessly—one side monitors horizon-spanning weather up to 48 nautical miles, the other zooms on close-quarters action. Pulse compression and beam sharpening ensure crisp separation of small targets, like buoys from birds or distant trawlers. Whether chasing fish schools or plotting coastal cruises, this versatility means you're never blind-sided, adapting seamlessly to evolving conditions.

Smart Modes for Every Voyage

Switch effortlessly between harbor mode for cluttered ports, offshore for open water, weather to pierce squalls, or bird mode to locate bait balls. MARPA tracks up to 20 targets in dual range, auto-acquiring vectors for speed and course predictions. Low-profile with integrated LEDs for night ops, it powers up instantly—no warm-up wait—perfect for impulse launches or sudden fog banks.

Efficient Power and Rugged Build for Real Boating

Solid-state tech sips power (under 30W peak), fitting 12/24V setups with reverse polarity protection. Weighing just 14.9 lbs, it's a breeze to mount on arches or poles. IPX6 waterproofing and -25°C to +55°C tolerance shrug off gales up to 100 knots. X-band precision (9.4-9.5 GHz) with adjustable beam widths (down to 2°) sharpens your edge without side-lobe interference.

Why Boaters Swear by HALO24

Fishermen love bird mode for hidden schools; sailors praise dual range for race courses amid fleets. Powerboat owners tout its low draw for extended trips. Unlike older magnetron units, no heat buildup means reliable performance hour after hour. Pair it with modern chartplotters for overlays that turn data into decisions—fish safer, sail smarter, navigate bolder.

Pro tip: Calibrate target separation for your conditions—high for foggy days, off for clear skies—to maximize discrimination. Regular lens wipes keep echoes pure, extending its sharp-eyed vigilance.

Equipped with a compact 24-inch dome radar at 60RPM! The Simrad Halo 24 dome radar revolutionized the radar industry, providing unparalleled clarity, detection capabilities, and separation capabilities for short-range and long-range targets. Halo24 is very suitable for sailing, fishing and small motor boats. The compact 24-inch dome allows you to view two areas at once, so you can watch nearby rowers and upcoming traffic anytime, anywhere. The use of 2 antennas and continuous wavelength measurements instead of time-based measurements enables wideband radars to produce unparalleled close range performance, down to 200 feet. There are no dead zones on board, while still providing a range of up to 48 nautical miles. Halo24 is the industry's first 60 RPM rotation with a maximum rotation distance of 1.5 miles, making it the ultimate collision avoidance device. In this way, a complete 360-degree scan can be performed every second. You will see the update at a closer distance. VelocityTrack Doppler technology can apply color codes to the target according to the direction of the target or away from your current location, so that you can instantly see the targets around you. Targets that may be dangerous or approaching you will be displayed in yellow, targets that are not currently threatened or far away from you will be displayed in blue, and fixed targets will be displayed in red. Add an optional heading sensor. When used in low visibility or no visibility conditions, Simrad Halo24 may be overlaid on the chart page to find out your location. Advanced pulse compression technology with beam sharpening function can achieve ultra-clear target separation of smaller targets at closer and longer distances. The startup on Halo24 only takes a few seconds, and you can turn on the standby mode so that when you really need the radar, you can start it immediately. Simrad's Halo 24 adds a lot to your network settings.
