Humminbird APEX 19 MSI+ Cross Touch Fishfinder MFD

At 30 to 60-plus feet, a boat’s helm has room for a display most consoles simply can’t fit — and that’s exactly the buyer Humminbird built the APEX 19 MSI+ for. This is the flagship of the APEX line: an 18.5-inch Cross Touch display paired with 1,000 watts RMS of sonar power, aimed squarely at offshore sportfishing boats and yacht helms where screen real estate is a design choice, not a constraint.

Key Features

- 18.5″ Full HD Cross Touch IPS display at 1920×1080 — large enough to run three or four data panels simultaneously without anything feeling cramped.
- MEGA Side Imaging+ and MEGA Down Imaging+ with dual spectrum CHIRP — covers structure scanning at 455 kHz, 800 kHz, and the 1.2 MHz MEGA band in one built-in system.
- 1,000W RMS / 8,000W peak-to-peak sonar output — enough power for traditional CHIRP to hold bottom in deep water down to 3,500 feet, well past what most inshore anglers ever need.
- MEGA Live Imaging Network compatible — add Humminbird’s live sonar later and this display is already built to run it, no head-unit upgrade required.
- Dual Ethernet ports plus HDMI in/out — built for networking multiple displays and routing video to a second helm monitor, not just a single-station setup.

Who This Is For

Built for flagship offshore sportfishers, luxury yacht consoles, and large center consoles that want maximum touchscreen real estate — Humminbird specifies 30 to 60-plus foot hulls as the target range. It’s the wrong choice for a small boat: at 7 kg and 18.5 inches diagonal, this needs a console designed around it, not one it’s squeezed into.

Compatibility

Confirmed compatible: NMEA 2000 devices, dual Ethernet networking with other Humminbird displays, HDMI input/output for secondary monitors, and Humminbird’s MEGA Live Imaging transducer network. Water resistance is rated IPX7 for open helm dashboard splash exposure — not intended for submersion or below-deck wet mounting.

Warranty & Support

Covered by Humminbird’s 2-Year Limited Warranty, with a third year available free when you register the product.

Next to the APEX 16 MSI+ in the same line, the 19 is the head unit for a boat being built or refit from scratch — it includes the sonar hardware the 16’s “display only” configuration assumes you already have. If you’re outfitting a large center console or offshore boat as a complete system rather than adding to an existing one, this is the model built for that starting point.
