Humminbird APEX 13 MSI+ Chartplotter CHO Display Only

The APEX Cross Touch control heads scale down from 18.5 inches to 13.3 without losing any of the sonar processing that makes the line worth buying — the APEX 13 MSI+ CHO is proof of that, built as a display for a boat that already has a Humminbird transducer network running, not a first sonar purchase.

Key Features

- Same MEGA Side Imaging+, MEGA Down Imaging+, and dual spectrum CHIRP processing found on the larger APEX 19 and 16 — the smaller screen doesn’t mean a scaled-down sonar engine.
- 13.3″ Full HD Cross Touch display at 1920×1080 — enough resolution for split-screen chart-and-sonar without the console footprint the 18.5″ model demands.
- Dual Ethernet ports for networking into an existing multi-display Humminbird setup — built to join a system, not start one.
- Dual Micro SD slots — room to carry chart cards and offline map regions without swapping cards mid-trip.
- 3.1A power draw, the lightest of the APEX CHO family — worth checking against your electrical budget if you’re adding this as a third or fourth station.

Who This Is For

Fits boats already running Humminbird MEGA sonar or Live Imaging that want a mid-size second or third display — a bow station paired with a larger helm unit, for instance. It’s not a fit if you’re starting from zero: like its 16 and 19-inch siblings, this ships with no transducer and won’t read anything on its own.

Compatibility

Confirmed compatible: NMEA 2000 devices, dual Ethernet networking with other Humminbird APEX/SOLIX/HELIX displays, Bluetooth accessories, and Humminbird’s MEGA Live Imaging transducer network. Same limitation as the APEX 16 and 19 CHO units: no transducer included, and no sonar output until it’s connected to one.

Warranty & Support

Three sizes now sit in this CHO family — 13.3″, 15.6″, and 18.5″ — and the right call comes down to console space at the specific station you’re filling, not a features gap between them; the sonar processing is identical across all three.
