Experience marine navigation and angling at the next level with the Simrad NSS 4 12" Chartplotter and Fishfinder (SKU 000-16015-001) — a premium, all-in-one display built for sportfishing enthusiasts and serious cruisers alike.

Featuring the perfect blend of sleek design, rapid performance and advanced sonar capability, this unit transforms how you explore and fish the waters.

Key Features & Capabilities:

• Hybrid tri-control interface: effortless operation via touchscreen, rotary dial and keypad—so you’re in command whether calm or rough seas. 
• Premium glass-to-edge 12″ SolarMAX IPS display with 1280×800 resolution, >1200 nits brightness and wide viewing angles (80° top/bottom and left/right)—ideal for direct sunlight and polarized sunglasses. 
• Powered by a Qualcomm® 8-core processor and redesigned OS—enjoy smoother page transitions, ultra-fast auto-routing and responsive UI so you focus on boating, not waiting. 
• Built-in dual channel 1 kW CHIRP echosounder for superior target separation and clarity: reveal fish, structure and bottom details like never before. 
• Support for Active Imaging™ & Active Imaging™ HD: high-definition DownScan and SideScan sonar capabilities to detect structure, fish and composition with exceptional fidelity. 
• Charting covered: Includes C-MAP® Discover X chart card of North America out of the box and supports C-MAP Reveal X plus third-party charts such as CMOR and StrikeLines (check availability with provider). 
• Integration-ready: Seamless connectivity with Simrad® HALO® radars, RECON™ trolling motor, S3100H/S5100 sonar modules, Wi-Fi 5 (IEEE 802.11ax), micro-SD/SDHC card support, HDMI video in, IP camera inputs, and much more—future-proof your helm.

Why This Unit Stands Out:
Whether you’re trolling offshore or cruising coastal waters, the NSS 4 delivers a refined helm experience and advanced sonar capabilities that elevate both safety and fishing performance.

The 12″ display offers expansive visibility, while the multi-control interface ensures ease of use in all conditions. With built-in sonar and compatibility with high-end imaging modules, you get a full fish-finding and chartplotting suite in one unit. Its integration potential means you’re not just buying a display—you’re investing in a scalable marine electronics ecosystem.

Who Should Use It:

• Sport-fishing enthusiasts who demand best-in-class sonar and imaging to locate fish, structure and underwater terrain.
• Cruisers and serious boaters who want a premium navigation display with full integration of radar, autopilot, charting and vessel systems.
• Boat owners upgrading their helm to modern networked electronics, with the flexibility to add future modules and capabilities.

Installation & Notes:

• Transducer(s) for sonar features may be required separately depending on your setup. 
• Ensure chart compatibility: designed for C-MAP X-Gen charts (DISCOVER X, REVEAL X) and selected third-party support. Navionics is not supported. 
• Dual SD card slots on front of unit allow quick access to chart cards and memory expansion. 
• Bracket mount included; optionally supports rear-mount installation. Be sure to check depth & dimension requirements: display only 338.9 mm × 208.4 mm × 84.8 mm (13.34″ × 8.20″ × 3.34″); with bracket 367.8 mm × 232.8 mm × 84.8 mm (14.48″ × 9.17″ × 3.34″). 

Elevate your marine electronics and onboard experience with the Simrad NSS 4 12″. The premium screen, advanced sonar, deep integration and smart design combine to give you one of the most capable chartplotter-fishfinders available.

Get pro-level performance and reliability for your next fishing trip or cruising adventure.
