Simrad HALO 300X radar – Pros & Cons Guide

Introduction

The Simrad HALO 300X radar is a high-performance radar black box designed for serious mariners who demand unmatched detection capabilities, flexible installation, and industry-leading radar clarity. Delivering a powerful 130-watt output, the HALO 300X is engineered for advanced situational awareness in both close quarters and offshore operations — but it comes without an antenna, giving boat owners the freedom to choose the most compatible array size for their vessel.

Paired with a 20-meter cable, this radar system is ideal for large center consoles, commercial craft, and yachts seeking to upgrade to the latest in solid-state radar technology. With exceptional target separation, dual-range display, and instant-on readiness, this black box is compatible with Simrad’s top MFDs and can power radar displays up to 96 nautical miles.

Whether you’re navigating through fog, monitoring weather fronts, or tracking high-speed targets, the Simrad HALO 300X radar ensures you’re always in control with clarity and precision.

Overview / What Is Simrad HALO 300X radar

The Simrad HALO 300X radar is a black box solid-state radar system built for modern vessels that require maximum flexibility and unmatched detection range. Unlike bundled radar packages, this product includes a 130-watt radar processor and a 20-meter cable — but no antenna — allowing users to choose a compatible open-array antenna separately based on boat size and needs.

Key features include:

• 130W Solid-State Radar Technology
• No Antenna Included – Add 3′, 4′, or 6′ Array Separately
• Dual Range Display (up to 96NM)
• VelocityTrack™ Doppler Processing
• Low Power Standby Mode with Instant Wake-Up
• Advanced Target Tracking with MARPA (up to 100 targets)

This radar integrates seamlessly with Simrad NSS evo3S, NSX, and other compatible MFDs.

Choosing the Right Antenna for Simrad HALO 300X radar

Since the Simrad HALO 300X radar system does not include an antenna, selecting the appropriate open-array antenna is essential. Simrad offers 3-foot, 4-foot, and 6-foot antennas to match various vessel profiles.

Here’s how to choose the right one:

• 3’ antenna: Ideal for smaller boats where space is limited, offering great performance within 48NM range.
• 4’ antenna: Balanced option for most midsize boats, provides enhanced detection and target separation.
• 6’ antenna: Best for large vessels, supports full 96NM range and best beam clarity.

When choosing the antenna, consider mounting space, beam width, and usage frequency (offshore vs. inshore).

Simrad HALO 300X radar Troubleshooting Tips

Even the most advanced systems like the Simrad HALO 300X radar may experience operational issues if not correctly set up or maintained. Common issues and their solutions include:

Radar not displaying: Ensure the MFD software is updated, and the 20m cable is securely connected at both ends. Double-check power supply and fuses.

Target echo is unclear: Recalibrate sea clutter and gain settings via your display. Also, verify that the antenna is aligned and free from obstructions.

Radar won’t power on: Use a multimeter to check the voltage at the power port. Low voltage or corrosion in connectors can prevent startup.

If persistent issues occur, consult Simrad’s documentation or contact certified support services.

Simrad HALO 300X radar Cost and Durability

Pricing for the Simrad HALO 300X radar starts around $6,999 (excluding the antenna). While it may appear expensive, it’s an investment that pays off through advanced safety features, long-term durability, and future-proof solid-state design.

The system is sealed against moisture and corrosion, making it ideal for saltwater environments. With no magnetron to replace and low-power consumption, the HALO 300X is designed for long-term, low-maintenance use. Most owners report over 8-10 years of reliable service with proper care.

Maintenance Tips

To extend the lifespan and maintain the optimal performance of your Simrad HALO 300X radar, follow these practical maintenance steps:

• Monthly: Check cable connections for corrosion and secure mounting points for the antenna.
• Quarterly: Use fresh water to rinse the array (if attached) and clean the radome surface gently.
• Firmware Updates: Download latest software via Simrad’s support page and install via USB or networked MFD.
• Diagnostics: Use Simrad’s internal radar health check feature via your display unit for early issue detection.

Also store your radar in standby mode during extended docked periods to reduce wear and tear on internal components.

Detailed FAQ Section

What’s included in the Simrad HALO 300X radar package?

The Simrad HALO 300X radar package includes the 130W radar processor (black box), a 20-meter cable for connecting to the display and antenna, and mounting hardware for the processor. It does not include an antenna — this must be purchased separately. The package is compatible with Simrad MFDs like the NSS evo3S and NSX. This configuration is ideal for boat owners who want customization in their radar array size and type.

How to install the Simrad HALO 300X radar system?

To install the HALO 300X radar, first mount the black box in a secure, dry compartment close to power and data sources. Then run the 20-meter cable from the processor to the antenna and MFD. Ensure all connections are weather-sealed. After installation, use your MFD’s radar setup wizard to configure range, gain, and MARPA settings. If you’re unsure about alignment or radar tuning, consider professional installation to avoid errors.

What are the best antenna options for Simrad HALO 300X radar?

Simrad offers 3-foot, 4-foot, and 6-foot open-array antennas that are fully compatible with the HALO 300X. The best option depends on your boat’s size and use case. For example, sportfishers over 45′ often prefer the 6-foot array due to its wide beam and superior long-range clarity. For center consoles under 35′, a 3-foot array is more suitable and less space-intensive. Matching your vessel size and visibility needs is key to choosing the best antenna option.

How to troubleshoot HALO 300X radar connection issues?

If your HALO 300X radar is not connecting, start by checking that all cable ends are fully inserted and secured. Test voltage levels at the power input and ensure the MFD is updated with the latest Simrad software. If the radar still doesn’t respond, inspect the Ethernet/network ports for water damage or corrosion. Performing a system reset via your MFD may also resolve software-related issues. Contact Simrad technical support if problems persist.
