Marine electronics manufacturer Simrad has introduced a new Navigation Aid feature for its recreational HALO radar systems, designed to make identifying channel markers, navigational hazards, and nearby vessels easier for recreational boaters.
Announced on October 27, 2026, the technology combines radar information with electronic chart data to provide a clearer picture of surrounding waterways. The feature will also be available on compatible B&G radar systems.
For boat owners who regularly navigate busy channels, unfamiliar coastal waters, or areas with numerous navigation markers, this development could make radar displays more informative and easier to interpret.
What Is Simrad’s New Navigation Aid Feature?
Traditional marine radar detects objects by transmitting radio waves and analyzing their reflections. It can identify nearby vessels, landmasses, buoys, and other objects, even when visibility is limited.
However, radar alone does not necessarily tell the operator what an object represents.
A radar return might indicate a stationary object ahead, but determining whether it is a channel marker, another navigational structure, or a potential hazard may require consulting an electronic chart.
Simrad’s new Navigation Aid feature addresses this challenge by displaying recognizable navigation aid symbols directly within the radar application.
The system uses information from compatible C-MAP electronic charts to identify channel markers, special markers, and other navigational aids.
Instead of constantly switching between radar and chart views, boaters can interpret more information from one display.
How the New Technology Works
The Navigation Aid feature integrates information from three important marine electronics components:
- HALO radar: Detects nearby objects and potential obstacles.
- C-MAP electronic charts: Supplies information about charted navigation aids.
- Simrad multifunction displays: Combines the information into a radar presentation with additional symbols.
For example, imagine navigating a narrow channel where several markers and recreational boats appear on radar.
Without additional identification, the operator must interpret the radar returns and compare them with the chart.
With Navigation Aid enabled, the radar screen can display symbols identifying charted navigation markers, helping distinguish them from other radar targets.
This integration is particularly useful because not every object detected by radar represents the same type of navigational concern.
Importantly, the navigation symbols come from chart information. They should not be interpreted as independent confirmation that a physical marker is present or correctly positioned.
Working Alongside Simrad AutoTrack
The new feature complements Simrad’s existing AutoTrack radar technology.
AutoTrack helps identify and track moving vessels and potential hazards, giving boaters additional information about traffic around their vessel.
Navigation Aid adds another layer by identifying charted navigational markers.
Together, these technologies can help operators distinguish among moving vessels, stationary markers, and other radar targets.
Consider a recreational boater approaching a busy harbor entrance.
The radar may detect multiple vessels entering and leaving the channel, while fixed channel markers appear among the returns.
AutoTrack can assist with monitoring moving targets, while Navigation Aid helps identify charted markers.
The result is a more informative radar display that may reduce the time needed to interpret surrounding conditions.
However, neither feature replaces maintaining a proper lookout or following established navigation procedures.
Which Simrad Displays Will Support Navigation Aid?
According to Simrad’s announcement, the new feature will support several of its current multifunction display families.
Compatible Simrad displays include:
- Simrad NSX
- Simrad NSX ULTRAWIDE
- Simrad NSS 4
- Simrad NSO 4
The technology will also support the B&G Zeus S, Zeus S ULTRAWIDE, Zeus SR, and Zeus SRX.
The feature is scheduled to arrive with the NEON OS 2.6 software release during the fourth quarter of 2026.
Owners should verify software availability and compatibility with their particular equipment before assuming the feature is operational.
Do You Need New Charts or Radar Equipment?
One important consideration is that Navigation Aid requires compatible C-MAP charting.
Simrad identifies C-MAP DISCOVER X and REVEAL X as the supported chart products.
Boaters using other electronic charts should not assume they will receive the same functionality.
The feature is intended for Simrad recreational HALO radars and supported B&G systems, but a compatible radar alone is not sufficient. The multifunction display, software, and charting must also meet the requirements.
Existing owners should check their equipment configurations before purchasing additional hardware or chart subscriptions.
Simrad also allows operators to turn the feature on or off through the Vessels and Targets menu.
This flexibility is useful for boaters who prefer a simpler radar presentation in certain operating conditions.
Why This Matters for Recreational Boating Safety
Radar is particularly valuable during nighttime operation, rain, fog, and other situations where visibility becomes restricted.
However, interpreting radar information can be challenging, especially for less experienced operators.
Adding chart-based navigation symbols may help boaters understand what they are seeing more quickly.
Potential benefits include improved awareness of channel boundaries, easier identification of charted markers, and less frequent switching between display applications.
Nevertheless, electronic navigation aids have limitations.
Charts can contain outdated information, physical markers can move, and radar returns may be affected by weather, sea conditions, or equipment settings.
Boaters should continue using visual observations, updated charts, GPS, AIS where available, and appropriate navigation practices.
Is Simrad’s Navigation Aid Worth Having?
For boat owners already using compatible Simrad electronics, the new Navigation Aid feature could be a worthwhile software enhancement.
Its principal advantage is not simply displaying additional information, but presenting radar and chart information together in a way that may be easier to understand.
The feature could be especially helpful for boaters navigating unfamiliar waterways, congested harbors, and channels containing numerous navigation markers.
Whether it justifies upgrading an older electronics system depends on the equipment already installed, compatibility requirements, and the owner’s navigation needs.
As marine electronics become increasingly integrated, features like Navigation Aid demonstrate how manufacturers are working to make sophisticated navigation technology more accessible to recreational boaters.
For now, Simrad’s announcement represents a promising development in radar-based situational awareness, although real-world performance will need to be evaluated as the software becomes available.
