Humminbird APEX 13 MSI+ Chartplotter 13.3" Full-HD Touchscreen

The Humminbird APEX 13 MSI+ is Humminbird's flagship 13.3-inch multi-function display for serious anglers - the largest screen in the APEX series, the most processor power, the most networking capability, and the most sonar capability built in. For tournament bass and walleye anglers running serious electronics setups, multi-rig pontoon owners, and any angler who wants the best Humminbird chartplotter available with room to network multiple specialized transducers (MEGA Live, MEGA 360, 2D CHIRP for deep-water applications), the APEX 13 MSI+ is Humminbird's top-tier offering.

13.3-inch Full HD display. The display is a 13.3-inch diagonal Full HD LCD at 1920 x 1080 pixel resolution - the sharpest display in this size class on the Humminbird lineup. Full HD resolution matters specifically for sonar and chart detail viewing - the smaller a pixel size, the more detail you can see in MEGA Imaging sonar returns, the more precise chart features render, and the more usable information you can fit on a multi-pane split-screen view. Sunlight-readable for fishing in direct sun. Bright enough at full backlight to be readable in any lighting condition you'll encounter on the water.

Cross Touch interface - touch plus soft keys. The display works as both a touchscreen AND a soft-key bezel - all functions are accessible either way. Touchscreen is the default and works great in dry conditions for fast navigation. Soft keys on the bezel are critical for: heavy chop where touchscreen accuracy degrades, wet hands from fish handling, fishing gloves that touchscreens don't reliably register, and operation where you can't take your eyes off the water to touch precise screen locations. The hybrid interface is the best of both worlds - touchscreen speed when conditions allow, physical buttons when they don't. Many premium chartplotters use touchscreen-only - the APEX's Cross Touch is a meaningful usability advantage.

What MSI+ means. MSI+ stands for MEGA Side Imaging Plus - Humminbird's premium side-scanning sonar technology built into the chartplotter. The MSI+ designation in the model name tells you this APEX 13 includes both MEGA Side Imaging+ (the 200-foot side scanning) AND MEGA Down Imaging+ (200-foot down scanning) capabilities. Connect a compatible MEGA SI+ transducer to the chartplotter and you get the full MEGA imaging suite. Without the right transducer, even an MSI+ chartplotter can't deliver MEGA Imaging - the transducer is the key piece. The chartplotter is sold without a transducer in this listing - source the appropriate transducer separately based on your boat type and fishing application.

Built-in Dual Spectrum CHIRP. Beyond MEGA Imaging, the APEX 13 includes built-in Dual Spectrum CHIRP - the traditional 2D sonar you've always used (depth, fish arches, thermoclines, bottom hardness). CHIRP uses a range of frequencies (vs single-frequency fixed sonar) for better target separation and cleaner returns at typical fishing depths. Dual Spectrum means you can run high-frequency CHIRP for shallow detailed imaging OR low-frequency CHIRP for deep water - or split-screen both at once. Built-in means no separate sonar black box required for basic 2D CHIRP.

Dedicated 2 kW 2D CHIRP sonar channel. For serious deep-water applications (offshore tuna trolling, deep-water walleye on the Great Lakes, deep structure crappie fishing), the APEX 13 includes a dedicated sonar channel rated for 2 kW transducers - enough power to push CHIRP sonar to 5000+ feet depth with the right transducer. This is the differentiator vs lesser MFDs that max out at 1 kW transducers and 1500-2000 ft depth. For offshore use where you need real depth performance, the 2 kW capability matters.

MEGA Live Imaging compatible. The APEX 13 supports Humminbird's MEGA Live Imaging - the live-scanning sonar technology that competes with competing live-scan systems and the and ActiveTarget systems. MEGA Live shows you real-time fish behavior and structure around the boat, not just what passed under the transducer in the past. For tournament bass and walleye fishing where seeing fish reaction to your bait in real time is meaningful, MEGA Live is the difference-maker. Important: the MEGA Live transducer is sold separately - the APEX 13 chartplotter has the capability built in, but you need the MEGA Live transducer to deliver the live-scanning sonar feed.

MEGA 360 Imaging compatible. The APEX 13 also supports MEGA 360 Imaging - a full 360-degree sonar sweep around the boat extending 125 feet in all directions. The MEGA 360 transducer (sold separately, mounts on the trolling motor) physically rotates to scan the full 360-degree view. Useful for: idling over structure to see fish positions before stopping to fish, holding on a productive spot to monitor fish movement, and locating structure that would require multiple passes to find with directional sonar. Unique to Humminbird in the trolling motor mount category.

One-Boat Network integration. The APEX 13 is part of Humminbird's One-Boat Network ecosystem - the integrated control system that ties together Humminbird electronics, sister-brand sister-brand trolling motors, and sister-brand Cannon Optimum downriggers into one unified control experience. Control your trolling motor (Spot-Lock, AutoPilot, route follow) from the chartplotter touchscreen. Wireless downrigger control with depth automation. Shared waypoints, routes, and presets across all networked gear. For owners running a full Humminbird and sister-brand / Cannon ecosystem, One-Boat Network is a meaningful integration that eliminates separate control devices.

Preloaded mapping. The APEX 13 ships with detailed charts of more than 10,000 lakes plus coastal coverage for the continental U.S. - no separate chart card purchase required to get started. The lake mapping includes Humminbird's CoastMaster cartography and AutoChart Live (the ability to map a lake yourself in real-time during fishing, building custom contours as you cover the water - a powerful feature for fishing small unmapped private lakes or specific structure detail Humminbird hasn't published). Coastal coverage handles typical inshore saltwater navigation. For more detailed coastal navigation, add Navionics, C-MAP, or LakeMaster chart cards via the SD card slot.

NMEA 2000 networking. Full NMEA 2000 integration for: engine data (RPM, fuel flow, temp, alarms), VHF radio integration, AIS receiver / transponder, wind / depth / speed instruments, and any other NMEA 2000-compatible marine sensors and devices. The chartplotter displays NMEA 2000 data on dedicated instrument panels or as overlays on chart / sonar views. For boats with rich sensor networks, the APEX 13 is the unified display for all networked data.

HDMI in/out, WiFi, Bluetooth. The APEX 13 includes connectivity options most chartplotters don't have: HDMI input (display a video feed from a deck camera, FLIR thermal camera, or other HDMI-output device on the chartplotter screen), HDMI output (mirror the chartplotter display to a second monitor like a cabin TV or co-pilot screen), WiFi (smartphone app integration for software updates, chart updates, and remote display), and Bluetooth (for hands-free phone integration and accessory connections). The connectivity matters for owners building integrated marine electronics suites with non-Humminbird components.

Dual-core processor. The APEX 13 uses a dual-core processor - meaningfully faster than the single-core processors in older Humminbird MFDs. Practical benefits: smooth multi-pane display with multiple sonar feeds plus charts plus networking data all running simultaneously without slowdown, fast chart panning and zooming without lag, instant menu response, and the headroom to handle MEGA Live and MEGA 360 sonar feeds without performance issues.

What's NOT included. The APEX 13 MSI+ is the chartplotter HEAD UNIT only. NOT included: sonar transducer (essential - source the appropriate MEGA SI+ transducer separately based on your boat), MEGA Live transducer (separate purchase for live-scanning sonar), MEGA 360 transducer (separate purchase for 360-degree sonar), trolling motor (separate purchase for One-Boat Network integration), and any premium chart cards (preloaded mapping covers most use cases, premium cards are optional). Budget accordingly - a complete APEX 13 system with the right transducers and trolling motor integration runs significantly more than the chartplotter alone.
