Five screen-size classes. One connected X Series family.
Why X Series
FOUR REASONS. ONE DISPLAY.
01 / FIND
FIND FISH WITH CONFIDENCE.
Use Humminbird Imaging™ sonar to understand fish and structure beneath and around the boat.
02 / NAVIGATE
NAVIGATE WITH EASE.
Bring maps, waypoints and compatible navigation features into the same interface.
03 / CONTROL
CONTROL THE SYSTEM.
Access compatible motor and equipment controls without switching between separate interfaces.
04 / SEE
BUILT TO BE SEEN.
High-resolution displays designed for visibility in sunlight, rain and through polarised lenses.
Powered by Humminbird Imaging™
SEE MORE OF WHAT’S BELOW.
Different sonar views answer different questions. Understand what lies beside the boat, what is directly underneath and how targets appear in conventional sonar.
MEGA Side Imaging+
Look to either side of the boat to locate structure and explore a wider underwater area.
MEGA Down Imaging+
Examine structure below the boat with detailed downward imaging.
Dual Spectrum CHIRP
Use conventional sonar for depth information and fish-target separation.
Sonar capability requires a suitable connected transducer or networked sonar source. CHO packages do not include a transducer. Individual coverage and performance vary by model and installation.
Manufacturer navigation imagery. Features require compatible connected equipment.
Navigation that acts
FROM WHAT YOU SEE TO WHERE YOU GO.
01 / Draw & Navigate™
Choose the course on the touchscreen. A compatible connected trolling motor follows the drawn route, helping turn the plan into movement on the water.
02 / Intelligent Depth Control™
The system monitors depth changes and alerts the operator. Supported setups can engage Spot-Lock® and compatible shallow-water anchors when shallow water is detected.
03 / Wireless motor connection
Compatible displays and motors communicate wirelessly for connected boat control. Advanced sonar and other networks can still require Ethernet cables.
Expand each feature to explore the workflow. Confirm software and model compatibility; the operator remains responsible for navigation.
Five sizes / One X Series
FIND YOUR FIT.
Start with the available mounting space and the views your customer wants to use. Then choose the transducer configuration.
Suggested selection guidance, not fixed use categories. Size labels are nominal screen classes; actual diagonals and resolutions appear in the comparison below. Verify overall dimensions and mounting clearance on the product page.
Specify the right package
CHO OR CMSI+?
The key difference is the supplied transducer. Choose the package around the installation’s sonar source.
CHO
Control Head Only
No transducer is included. Specify a compatible transducer separately, use suitable built-in motor sonar, or share data from a supported networked fish finder.
Consider this for an existing compatible setup or an installation where the sonar equipment is being specified separately.
TRANSDUCER NOT INCLUDED
CMSI+
Control head + imaging transducer
Includes a compatible imaging transducer with the control head. Available in the supplied Marathon range for X9, X10, X12 and X16.
Consider this when the installation needs both the display and its supplied imaging transducer. Additional sonar and motor equipment are separate.
IMAGING TRANSDUCER INCLUDED
CHO does not mean every existing transducer will connect or deliver every sonar view. Confirm transducer compatibility, adapters, mounting hardware and the exact box contents with Marathon.

THREE PLACES TO START.
Explore a compact CHO display, our featured imaging package or the largest screen in the range.
Compact installations
X7 CHO
7-inch touchscreen and keypad control for installations where space matters. Specify the compatible sonar source separately.
Confirm UK chart coverage, product generation, software and required network accessories. Wireless motor connectivity does not mean every component operates without cables.

*Supported sonar modes require a suitable connected sonar source; a CHO box includes no transducer. MEGA Live 2, compatible motors, network hardware and chart upgrades are separate purchases. X7 CMSI+ is not listed in the supplied Marathon import. Specifications do not confirm stock or UK delivery dates.
Installation and compatibility checks
Check mounting clearance, power supply, required sonar sources and network accessories. Manufacturer guidance specifies an external GPS antenna for in-dash installations. Confirm the exact package and UK specifications with Marathon before ordering.
Display references: X7 · X9 · X10 · X12 · X16. Manufacturer references checked 7 October 2026; UK SKU links use Marathon’s supplied range.
