Humminbird APEX® 16 MSI+ Chartplotter CHO Display Only

Experience Unrivaled Clarity on the Water with APEX 16 MSI+

Imagine pinpointing fish and structure with breathtaking detail, even in the murkiest waters or at extreme depths. The Humminbird APEX 16 MSI+ Chartplotter CHO elevates your angling game by delivering the sharpest sonar images on a stunning 16-inch Full HD display. As a control head only unit, it gives seasoned anglers the freedom to pair it with their preferred transducer setup, whether you're upgrading an existing network or opting for a high-performance thru-hull mount for offshore adventures.

Crystal-Clear Imaging That Reveals Every Secret

At the heart of this powerhouse is MEGA Imaging+ technology, pushing side imaging out to 200 feet per side with 20% more detail and down imaging to 200 feet with enhanced clarity. Add MEGA Live for real-time motion sonar that lets you watch fish react to your lure in stunning live-action detail. Dual Spectrum CHIRP sonar sweeps wide frequencies for superior target separation, ensuring you distinguish between baitfish schools and trophy walleye effortlessly. The dedicated 2kW channel for accessory transducers means no compromises on power or performance.

Real-World Edge for Serious Anglers

• Spot subtle bottom changes that hold crappie in shallow bays.
• Track muskies hugging weed edges in 50 feet of water.
• Navigate structure-heavy reservoirs with confidence during low-light bites.

Intuitive Cross Touch Control Meets Blazing Speed

The brilliant 1920 x 1080 resolution display pops under sunlight or helm lighting, while the Cross Touch interface lets you toggle seamlessly between touchscreen swipes and precise keypad inputs—gloved hands in rough seas? No problem. A dual-core processor powers split-screen views of sonar, charts, and networking data without lag, so you stay locked in on the action.

Customize your dashboard with sidebar menus for personalized combos: overlay MEGA 360 sweeps on live charts or pair sonar returns with forward-facing views for tournament-winning intel.

Build Your Ultimate Fishing Network

One-Boat Network compatibility transforms your setup. Sync with Minn Kota trolling motors for spot-on GPS anchoring or i-Pilot spot-lock precision. Wirelessly command Cannon downriggers from the screen, dialing in depths without leaving the helm. Dual Ethernet ports eliminate hubs for clean multi-head networks, while HDMI in/out supports cameras for live well monitoring or secondary screens. NMEA 2000 pulls in engine data, weather feeds, and more—Bluetooth handles software updates and phone alerts via the FishSmart app.

Pro Tip: Network Like a Champion

Link multiple APEX units for 360-degree awareness: one head for bow sonar, another at the console for charts. Add MEGA 360 for stationary sweeps around docks or brush piles, revealing fish you never knew were there.

Superior Mapping for Precision Navigation

Built-in GPS pairs with Humminbird's enhanced basemap, charting over 10,000 lakes and coastal U.S. waters with contours, hazards, marinas, and depth markers. AutoChart Live lets you record custom maps on the fly—depth, hardness, vegetation—for replaying hot spots next trip. Expand with LakeMaster for high-def lake detail or Navionics for offshore vectors, unlocking contour reliance mode for shaded relief that mimics real bottom profiles.

Why Opt for Control Head Only?

This CHO model shines for custom rigs. Mount it with a Minn Kota motor's built-in MEGA Imaging, share data from Ethernet-linked units, or select transducers like stainless steel thru-hulls for bluewater stamina. It's ideal for expanding systems without redundancy, keeping your boat lean and mean.

Ready for Any Fishing Challenge

Whether chasing bass in tournaments, walleye at night, or stripers offshore, the APEX 16 MSI+ CHO delivers pro-grade tools in a flexible package. Its rugged build handles spray, vibration, and long days, backed by Humminbird's commitment to innovation.
