Lowrance HALO20 Plus Radar: The Ultimate Compact Marine Radar for Boaters

Introduction

This article explores everything you need to know about the Lowrance HALO20 Plus, including its features, benefits, installation tips, real-world performance, and frequently asked questions.

What is the Lowrance HALO20 Plus Radar?

The Lowrance HALO20+ Radar is a 20-inch compact pulse compression radar dome designed for small to medium-sized powerboats. As part of the HALO family from Lowrance, it integrates advanced radar technology, including VelocityTrack™ Doppler, MARPA target tracking, and dual-range operation. This model bridges the gap between entry-level radar systems and professional-grade marine radar, offering a blend of affordability and top-tier functionality.

Key Features of the Lowrance HALO20 Plus

1. VelocityTrack™ Doppler Technology

VelocityTrack™ Doppler allows the radar to instantly identify whether a target is moving toward or away from your vessel. Color coding (usually red for approaching and green for receding) provides at-a-glance information that enhances situational awareness and safety.

2. 20-Inch Dome Design

The HALO20+ sports a compact, low-profile 20-inch dome that fits neatly on most vessels. Its streamlined design ensures minimal wind resistance and a modern aesthetic.

3. Pulse Compression Technology

Pulse compression enables the radar to deliver high resolution at both short and long ranges simultaneously. This means small, fast-moving objects close to the boat and larger vessels farther away are both clearly displayed.

4. Dual Range Operation

Dual-range mode lets users monitor two ranges at once on a single screen. For example, you can keep an eye on close-range hazards while also tracking weather systems or vessels miles away.

5. InstantOn™ Technology

From standby mode, the HALO20+ can power up instantly, making it ideal for boats that need fast radar access. No warm-up time means more immediate situational awareness.

6. Range Capability

The radar boasts a range of up to 36 nautical miles, providing excellent coverage for coastal navigation, offshore fishing, or channel monitoring.

7. MARPA Target Tracking

With MARPA (Mini Automatic Radar Plotting Aid), the radar can track up to 10 targets simultaneously, enhancing collision avoidance and navigational safety.

8. Advanced Signal Processing

The HALO20+ automatically adjusts its settings to optimize signal return, reducing clutter and providing a clearer view of the surroundings.

Benefits of Using the Lowrance HALO20 Plus

1. Enhanced Navigation Safety

Whether you’re navigating through fog, rain, or at night, the HALO20+ provides critical information to avoid collisions with other vessels, buoys, or land.

2. Compact and Easy to Install

Its lightweight and low-profile design make it easy to install on center consoles, fishing boats, and cruising vessels without adding bulk or requiring large mounts.

3. Immediate Access to Radar Data

With InstantOn™ functionality, there’s no delay in boot-up time, offering peace of mind when rapid decisions are needed.

4. Low Power Consumption

The radar operates efficiently with low power draw, making it ideal for boats with limited electrical systems or battery setups.

5. Highly Intuitive Interface

When paired with Lowrance multifunction displays (MFDs) like HDS LIVE, Elite FS, or HDS Carbon, the radar interface is user-friendly and offers customizable viewing options.

Use Cases for the Lowrance HALO20 Plus

• Recreational Boating

Perfect for weekend boaters and coastal cruisers looking for reliable radar functionality without breaking the bank.

• Sportfishing

The radar can help identify flocks of birds (a sign of baitfish) or detect other fishing vessels in the area.

• Night-Time Navigation

For those who venture out at night, the HALO20+ provides critical visibility in pitch-dark environments.

• Harbor Navigation

Busy waterways can be a hazard. This radar offers high-definition short-range detection to avoid collisions while docking or maneuvering in tight spots.

Installation Tips for the HALO20 Plus Radar

Installing the HALO20+ is a relatively simple process, especially for users familiar with Lowrance MFDs. However, attention to detail is essential to ensure optimal performance.

1. Choose the Right Mounting Location

The radar should be mounted as high as possible on the vessel, clear of obstructions.
Avoid placing it near magnetic compasses or VHF antennas to prevent interference.

2. Power Requirements

The radar requires a 12-24V DC power supply.
Ensure the power cable is connected to a fuse-protected circuit.

3. Networking

Connect the radar to your Lowrance MFD via Ethernet cable.
Update the MFD software to the latest version to ensure compatibility and performance.

4. Calibration

Use the on-screen instructions to complete radar calibration.
Perform a radar tuning procedure to optimize signal quality.

Performance in Real-World Conditions

In various tests and real-world scenarios, the Lowrance HALO20 Plus consistently delivers:

Sharp short-range detection (within 100 feet)
Stable long-range performance (up to 36 nm)
Minimal clutter and false echoes
Clear target separation, even in rough seas
Exceptional tracking of moving targets using Doppler

Users report that it performs admirably in both open ocean and coastal environments, offering reliable information even in fog, rain, and night-time conditions.
