Simrad NSS12 evo3S 12 inch Combo MFD + Halo20+ Bundle (No HDMI)

This bundle pairs Simrad's NSS12 evo3S 12-inch combo MFD with the Halo20+ 20-inch pulse-compression dome radar, sold together as a single MPN so the helm arrives ready to wire as a complete chart-plus-radar setup. It's the configuration most owners of 25-to-40 ft sportfishers and cruisers actually want: one screen at the helm, native radar overlay, built-in sonar, and the headroom to add transducers, autopilot, and engine integration later without changing displays.

The NSS12 evo3S is the latest revision of Simrad's NSS combo line, built around the iMX 8 integrated six-core processor that roughly doubles page-load time compared with the original NSS evo3. In practical terms, chart pan and zoom is buttery, split-screen layouts (chart plus radar, chart plus sonar, chart plus 3D perspective) switch without hesitation, and the multi-touch overlay tracks finger input as cleanly as a current-generation phone. The 12-inch SolarMAX HD IPS panel runs 1280x800 at 1200 nits with 80-degree viewing angles top, bottom, left, and right, optically bonded to prevent fogging in the heat, with polarized-sunglasses-friendly behavior built in.

The built-in sonar is the part that often gets undersold. The NSS12 has a 1 kW dual-channel CHIRP echo sounder on board, with two transducer ports so you can run a wide-band CHIRP transducer plus an Active Imaging or StructureScan 3-in-1 transducer on the same display without an external sonar module. It supports ForwardScan (forward-looking shallow-water depth) for navigating onto unfamiliar anchorages, plus the down-vision, side-vision, and 3D imaging built into Active Imaging. For owners running deeper offshore, the S5100 external sonar module networks in over Ethernet for high-end big-game sonar.

Charting is preloaded with US C-MAP coverage, including the C-MAP Reveal layer that exposes high-resolution ocean-floor detail in Florida. The display also accepts Navionics (Gold, NAV+, Platinum+), C-MAP MAX-N and N+, CMOR, and Florida Marine Tracks cards on the microSD slot, so the chart strategy travels with the owner regardless of preferred provider. UI improvements in the evo3S revision include a dark wallpaper mode, an expandable audio sidebar, a one-tap chart-orientation button, and a live tide graph in the instrument bar.

The Halo20+ is the small-dome flagship of Simrad's pulse-compression radar line. The 20-inch dome puts out the same pulse-compression technology and VelocityTrack Doppler analysis that the Halo24 and larger Halo open arrays use, in a compact housing that fits radar arches and small radar masts that can't take a bigger dome. Range is up to 36 nautical miles, which covers practical detection for a 25-to-40 ft cruiser comfortably, and the dome spins at 60 RPM at close ranges up to 1.5 nm (versus the 24 RPM that most recreational radars run), which produces an almost real-time picture for close-in collision avoidance in crowded harbors.

VelocityTrack is the Doppler differentiator. Every return on the screen is color-coded by motion: approaching targets show up in a saturated color that grabs your attention, diverging targets fade into a neutral tone, and stationary returns (buoys, shoreline, fixed structure) stay in the background. The radar checks every target in range automatically, with no need to manually select MARPA targets one at a time, and there's no software cap on how many targets can be tracked simultaneously. MARPA itself is still available for explicit target tracking, up to 10 targets in single range or 20 in dual range.

Dual Range mode is the other Halo20+ feature that matters most underway. The radar transmits and processes at two ranges at the same time, so the chartplotter can show a short-range picture for collision avoidance in one window and a long-range picture for weather and traffic awareness in another, both fed from the same dome. Five operating presets (Harbor, Offshore, Weather, Bird, Custom) tune the radar's signal processing for the situation without requiring you to manually adjust gain, sea clutter, and rain clutter.

Connectivity is the NSS evo3S strength. Two Ethernet ports network sonar modules, additional MFDs, and IP cameras. NMEA 2000 handles engine, fuel, tank, and instrument data. NMEA 0183 covers legacy AIS receivers and older instruments. Composite video inputs handle camera feeds, and built-in Wi-Fi plus Bluetooth let you mirror the display to a phone or tablet through the Simrad app for remote viewing while you handle lines.

What's in the box. The NSS12 evo3S display itself, the Halo20+ dome with mounting hardware, a 10-meter scanner cable, an RJ45-to-5-pin Ethernet adapter, the NSS12 power cable kit, U-bracket and panel mount kits, bezel trim, sun cover, and the documentation pack. The 12V house bank powers both, drawing a max of 28W from the display plus the Halo20+ standby and transmit loads, well within a typical sportfisher's electrical budget.
