Features of Simrad NSX Smart Chartplotter & Fish Finder
Next-Gen Touchscreen Interface
The NSX features a SolarMAX IPS display available in 7″, 9″, and 12″ sizes, delivering >1200 nits brightness for crisp visibility in direct sunlight and compatibility with polarized sunglasses. Its 85° viewing angles ensure clarity from any helm position. The interface prioritizes intuitiveness with an Activity Bar for instant app switching and drag-and-drop customization for personalized dashboards. Users can edit instrument bars, create split-screen views, and toggle full-screen mode with one touch, eliminating complex menus and reducing onboard clutter.
Advanced Sonar & Imaging
Equipped with an Active Imaging 3-in-1 transducer (standard on 7″/9″ models), the NSX delivers:
CHIRP Sonar: Clear target separation and depth penetration.
SideScan/DownScan Imaging: Captures high-resolution images up to 300 feet laterally and below the vessel.
FishReveal: Overlays sonar data onto DownScan imagery to highlight fish-holding structures.
For deep-water fishing, the NSX supports 1kW transducers (sold separately for 12″ models), enhancing detail at depths exceeding 180 meters.
C-MAP Cartography Mastery
Pre-loaded with C-MAP DISCOVER X charts, the NSX offers:
- 1-foot contour detail and high-resolution bathymetry for precision depth tracking.
- 3x faster auto-routing (vs. older Simrad models) with obstacle/tide avoidance.
Upgrade to REVEAL X for satellite overlays and shaded relief coastal imagery. The Map Inspection tool provides one-tap access to buoy data, marina services, tides, and hazards. Third-party charts (e.g., CMOR, StrikeLines) are regionally supported via optimized cards.
Smart Integrations
The NSX seamlessly connects with:
Radar/Autopilot: Integrates with Simrad HALO pulse-compression radar (up to 72 nm range) and NAC-series autopilots for route-following or trolling patterns.
Mercury Engines: Monitor diagnostics, adjust troll speed, activate SkyHook anchoring, or control trim via the dedicated Mercury app.
SiriusXM: Live weather, fish-mapping alerts, and music (WM-4 module + subscription needed).
Sonar Sharing: Stream sonar data between multiple NSX units for multi-station viewing.
Setup Wizard & Companion App
A guided Setup Wizard simplifies installation, auto-configuring Sonar and vessel specs (draft and beam). The Simrad Companion App enables:
Wireless chart updates and trip planning.
Sync for waypoints, routes, and tracks.
Software upgrades via Wi-Fi or SD card.
Note: Screen mirroring is not currently supported.
Software & Future-Proofing
The 2023–2025 software updates introduced:
C-MAP X-Chart Manager: Direct chart purchases/updates without cards.
Third-party chart compatibility (e.g., Florida Marine Tracks).
Enhanced autopilot/Mercury control integrations. Regular updates ensure ongoing feature expansions, keeping the NSX ecosystem adaptive.

Simrad NSX Smart Fish Finder Setup Wizard & Installation Guide
Step 1: Pre-Installation Preparation
Disconnect the Kayak battery to prevent electrical shorts.
Gather components: Chartplotter unit, mounting bracket, power cable, transducer (if included), sun cover, and termination cap.
Verify compatibility: Ensure your vessel’s NMEA 2000 network (if present) uses Micro-C connectors.
Step 2: Mount the Chartplotter
Position the bracket:
Choose a flat, reinforced surface near the helm (avoiding compass interference).
Mark drill holes using the bracket as a template.
Secure the bracket:
Drill pilot holes and apply marine sealant to prevent water intrusion.
Attach with supplied screws (torque to 2.5 Nm).
Attach the NSX unit:
Slide the chartplotter onto the bracket until it clicks.
Insert the security screw to deter theft.
Step 3: Install the Transducer
(Skip if using an existing compatible transducer)
Mount the transducer:
Position the Active Imaging 3-in-1 transducer on the transom:
Location: 15–46 cm (6–18″) from the keel, avoiding strakes or turbulence.
Angle: Parallel to the waterline (0° tilt).
Secure with stainless steel screws + sealant.
Route the cable:
Run the 7.5m cable through the bilge/conduit to the helm.
Leave slack for steering movement.
Step 4: Electrical Connections
Power wiring:
Connect the red wire to the battery’s positive (+) terminal.
Connect the black wire to the negative (-) terminal.
Install the included fuse (2A for 7″, 3A for 9″/12″).
Network integration:
Plug the NMEA 2000 Micro-C connector into the chartplotter’s port.
Connect to an existing NMEA 2000 backbone (or install a starter kit).
Transducer plug:
Insert into the “xSonic” port on the chartplotter.
Seal unused ports with the termination cap.
Step 5: Setup Wizard Activation
Power on the NSX:
Reconnect the battery and press the power button.
Follow on-screen prompts:
Language/Region: Select your location.
Vessel Setup: Enter Kayak specs (draft, beam, length) for accurate auto-routing.
Transducer Setup: Confirm detection of the Active Imaging transducer.
Network Pairing:
Link Simrad HALO radar or autopilot if available.
Enable Mercury® engine integration via the “SmartCraft Connect” app.
Chart Activation: Insert the C-MAP Discover X card (included).
Step 6: Post-Installation Calibration
GPS calibration:
Navigate to “Settings” > “System” > “GPS Calibration.”
Cruise at >5 knots in open water for 5 minutes.
Sonar tuning:
Adjust “Frequency” (Low CHIRP for depth, High for detail) and “Sensitivity” in shallow water.
Software updates:
Connect to Wi-Fi or insert a MicroSD card to install the latest firmware.
Critical Tips & Warnings
Avoid These Mistakes
Transducer positioning: Never mount behind strakes or near propellers (causes turbulence).
Network overload: Do not exceed 4 devices on NMEA 2000 without a power inserter.
Sealing: Waterproof all deck penetrations with butyl tape or sealant.

FAQs About Simrad NSX Smart Chartplotter & Fish Finder
Does Simrad NSX support third-party charts like Navionics?
No, the Simrad NSX exclusively uses C-MAP Discover X and Reveal X charts. While it supports region-specific third-party options like CMOR (US only) and StrikeLines via optimized SD cards, it does not accept Navionics, Garmin, or other generic chart formats. This ensures optimized performance but limits flexibility for users invested in alternative ecosystems.
What transducers are compatible with Simrad NSX?
The NSX supports:
- Active Imaging 3-in-1 transducer (included with 7″/9″ models for CHIRP, SideScan/DownScan).
- xSonic 600W/1kW transducers for deep-water scanning.
- B258 1kW transducer via a 7-pin adapter.
- It is not compatible with Garmin transducers (e.g., GT41) or legacy Lowrance models.
Can Simrad NSX network with older Simrad units like NSS Evo3?
No, the NSX cannot network with non-NSX Simrad devices (e.g., NSS Evo3 or Lowrance HDS Live). Sonar sharing, radar, and autopilot integrations are only possible between NSX units. This restricts mixed-fleet upgrades but ensures streamlined performance within the NSX ecosystem.
How does the Simrad Companion App work with NSX?
The app enables:
- Wireless chart/software updates via Wi-Fi or SD card.
- Trip planning with route/waypoint syncing between mobile devices and the NSX.
- Device registration and manual access.
- It does not support screen mirroring or remote control of the NSX display.
Is the Simrad NSX display visible in direct sunlight?
Yes, the SolarMAX IPS touchscreen (>1200 nits brightness) offers 85° viewing angles and remains clear in direct sunlight. Its anti-glare coating ensures visibility even through polarized sunglasses, with no color distortion or blurring during rapid zoom/pan actions.
Recommended Accessories for Simrad NSX Fish Finder
For kayakers, the NEP-3 Ethernet 5-Port Switch enables seamless networking of radar, sonar, or autopilot modules within the NSX ecosystem, critical for tight-space setups. The WM-3 Tri-Cable Splitter integrates SiriusXM weather/fish mapping, delivering real-time hazard alerts essential for open-water safety.
A Micro-SD Card Reader ensures offline access to high-resolution C-MAP Reveal X charts when beyond cellular range. These add-ons maximize situational awareness and fishing efficiency in minimalist kayak rigs.
