*M: Mid-Chirp, L: Low-Chirp, H: High-Chirp
●Unit dimensions: W297×D127×H249mm approx. 3.0kg
●Unit voltage/power consumption/current: DC11~30V approx. 24W approx. 2A/12V
●Accessories: Main unit & bracket, power cord, transducer, hard cover, Type-C conversion cable for USB memory
●Equipped with Wideband Mode
Our original development! Equipped with HONDEX ClearChirp™ Fishfinder!
Conventional fishfinders transmit sound waves into the sea at a single frequency and display the received signals as images.
In contrast, the chirp method transmits sound waves while gradually changing the frequency, and processes the received signals for image display.
This significantly improves resolution and allows for clearer imaging of fish.
●Chirp Image Examples●



Furthermore, to realize this chirp technology, a dedicated broadband transducer capable of outputting signals over a wide frequency range is required. By developing both the main unit and the transducer in-house, we can achieve optimal settings and produce detailed images.
Broadband Transducers Compatible with ClearChirp™ Fishfinder
Broadband transducers for ClearChirp™ are available in TD320/TD340/TD361/TD380.
The frequencies are 90kHz to 140kHz for Mid-Chirp, 38kHz to 70kHz for Low-Chirp, and 130kHz to 220kHz for High-Chirp.
●Broadband Chirp Transducers●

The HDX-10C is also equipped with Wideband Mode! You can select the frequency.
In Wideband Mode, by connecting a broadband transducer, you can select frequencies in 5kHz steps for low range and 10kHz steps for mid and high ranges. Selecting and changing the optimal frequency according to the fishing ground and target fish species is also effective in reducing interference and noise from other vessels' fishfinders.

【NEW】Equipped with White Line function
Emphasizes the boundary of the seabed with a white line.
The display level can be set, allowing you to adjust how the seabed appears according to the fishing spot and target.
It makes it easy to distinguish between fish and the seabed, making it ideal for fishing for schools of fish near the bottom.
*Scheduled to be available from shipments in April 2026

Equipped with Depth Mapping® function!

【NEW】Depth Mapping® function memory capacity increased 10x
The memory capacity has been increased by 10 times, allowing for 1000 hours of recording inside the unit.
This allows you to save more "personal spots" and further expands the enjoyment of fishing.
*Planned for units shipped from April 2026 onwards
【Depth Mapping® PV】
【NEW】GPS Buoy Display Function
By inputting data from a GPS buoy receiver, the position of the GPS buoy can be displayed.
We do not sell GPS buoys, so customers need to prepare them separately.
Please contact your nearest dealer for details.
*Scheduled to be supported from units shipped in April 2026.
*An optional NMEA input/output cable (XC-109H) is required to use the GPS buoy display function.
*Maximum of 10 targets.
*GPS buoy tracks disappear when the power is turned off.

Smartphone/Tablet Compatible
The images displayed on the main unit can be mirrored on a smartphone or tablet.
Basic operations can also be performed from a smartphone or tablet.

For detailed information on tested devices (smartphones/tablets) for connection with the HDX series, please refer to the following.
*Operation may be unstable depending on communication conditions.
*For iOS, it may not operate depending on the OS version and Safari version.
Large Memory Capacity
Compared to conventional models, the memory capacity for tracks and marks is significantly larger.
Smooth Map Rendering
Compared to conventional models, smoother map rendering is now possible. *GPS reception frequency: 5 times/1 second
Data can be saved with a USB port
The main unit is equipped with a USB port, so you can move and save mark data and images from the main unit to a commercially available USB flash drive (32GB or less) without the need for an optional memory card.
*USB flash drive is not included.
*The HDX-10C is equipped with a USB (Type-C) port. To connect it to your existing USB flash drive (Type-A), connect the included USB flash drive Type-C conversion cable to the main unit.
*The USB flash drive that can be used with the HDX-10C is up to 32GB. We do not guarantee the operation of all USB flash drives. Depending on the type, it may not operate correctly.
Main Functions of HDX-10C
The HDX-10C is equipped with a variety of functions unique to HONDEX fish finders.
● Fish size display
The digital series adds size display to the popular fish character function.
It can be judged by sizes 1 to 99, and in addition, a "display/hide" one-touch function and a two-screen display with the normal screen have been adopted so that reactions can be checked instantly with actual images.
*This function is only valid in fish mark mode. Also, it can be used within a 100m range.
*The numerical values for the size display may have errors due to various factors. Please consider them as reference values only.
● Fish depth display
The fish character display has been enhanced with height from the seabed and depth from the sea surface (unit: m).
*This function is only valid in fish mark mode. Also, it can be used within a 100m range.
*The numerical values for the depth display may have errors due to various factors. Please consider them as reference values only.
● Dual-screen display of the same frequency
Fishfinder images of the same frequency can be split into two screens, and their sensitivities can be adjusted individually.
By comparing the two screens, optimal sensitivity can be set.
● Full-screen sensitivity adjustment
With traditional fishfinders, changing the sensitivity would apply from that point forward. However, digital fishfinders now allow for sensitivity changes on the screen (past records).
With this function, sensitivity can be adjusted while viewing the entire screen (past records), allowing even beginners to manually set clear images.
Bright screen with wide viewing angle & bonded LCD
The display unit has a very high resolution of 800x600 dots, allowing for clear display of fine details and characters.
Additionally, the adoption of a high-brightness LCD (1000 candelas) ensures excellent visibility even in bright conditions such as direct sunlight.
Furthermore, the bonded LCD improves visibility and prevents condensation.
Built-in GPS antenna, monitor connection system compatible
The HDX-10C has a built-in GPS antenna. *When using the built-in antenna, reception may not be possible depending on the mounting location and method.
Additionally, the HDX-10C can be connected to a monitor (no modification fee required!), allowing the same screen to be displayed at a remote location on the boat.
