Simrad HALO24 Pulse Compression Radar Dome, 24 in, 48 nm, 60 RPM, VelocityTrack Doppler

Overview

The Simrad 000-14535-001 is a 24-inch dome radar (HALO24) that uses Doppler target coloring and pulse compression to keep close-range traffic readable while still reaching out to a 48 NM scale. At short ranges it can spin up to 60 RPM, so the picture refreshes fast when you are threading a channel, running in haze, or dealing with mixed traffic around the harbor.

It runs on 12V or 24V systems (10.5 to 31.2 VDC) and connects to a compatible Simrad MFD over Ethernet (100 Base T). The dome measures 610 mm in diameter and 225 mm high, weighs about 6.9 kg without cable, and carries an IPX6 water rating for exposed installations on a hardtop, arch, or mast platform.

Key features

• 48 NM max range scale from a 24-inch dome, with pulse compression for usable detail at shorter ranges
• VelocityTrack Doppler coloring helps show whether targets are moving toward you or away from you
• Dual Range mode lets you view near and far ranges at the same time
• Up to 60 RPM rotation at close range (up to 1.5 NM) for faster updates in tight quarters
• Target separation control can narrow the horizontal beam to about 2° on High for better separation in clutter
• Minimum range capability down to 6 m (19.7 ft) for close-in awareness around docks and moorings
• 12V/24V compatible input (10.5 to 31.2 VDC), with a recommended 5A fuse
• Ethernet 100 Base T network connection to supported Simrad multifunction displays
• IPX6 water rating and operating temperature range of -25°C to +55°C

Installation and setup

Mount the dome where it has the clearest 360-degree view you can give it, with as little shadowing from masts, antennas, or a hardtop as possible. The dome footprint is 610 mm (24 inch) in diameter, so confirm you have enough flat area for the base and cable routing, plus clearance for the cable bend and drip loop.

Power is a simple red and black feed with a separate yellow power-control wire for how you want the radar to switch on and off. Keep the fuse or breaker close to the supply, and route the cable away from ignition wiring, high-current runs, and sources of heat. For the data side, the scanner uses Ethernet; seal the deck or hardtop penetration carefully and use the waterproof boot so washdowns do not wick water into the connection.

Compatibility and system integration

HALO24 ties into a Simrad MFD over Ethernet (100 Base T) and supports common radar viewing modes such as Harbour, Offshore, Weather, Bird, and Dual Range. If your boat already has an Ethernet backbone for sonar or radar, plan your port availability and cable routing before you drill, especially if the display is inside a console with limited access.

MARPA tracking is supported (up to 10 targets, or 20 in Dual Range mode) when paired with a compatible display setup. If your system uses radar overlay or advanced tracking features, make sure the rest of the network is set up to provide the heading and navigation data your display expects.

Use cases on board

This dome is a good match for smaller powerboats, center consoles, and sailboats that need a radar picture that updates quickly in close quarters without giving up the ability to watch weather cells farther out. Bird mode is also useful when you want to scan for surface activity while running offshore, as long as the radar is mounted high enough to keep the beam clear.

What’s included

• Cable, RJ45 to 5-pin, 1.5 m (4.9 ft)
• RJ45 waterproofing boot
• 10 m cable for HALO dome radar

Maintenance and care

Rinse the dome with fresh water after salt exposure and wash with mild soap when needed. Avoid abrasive pads and harsh solvents, and do not aim high-pressure spray directly at cable seals or connectors. Periodically check the mounting fasteners, cable strain relief, and the condition of the waterproof boot to keep water out of the connections over time.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
