●Wideband mode equipped
Our Own Development! Equipped with HONDEX ClearChirp™ Fishfinder!
Conventional fish finders 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 specially to display images.
This significantly improves resolution and allows for clearer depiction of fish.
●Chirp Image Examples●



Furthermore, to realize this chirp technology, a dedicated wideband transducer capable of outputting signals over a wide frequency range is required. By developing both the main unit and the transducer in-house, we are able to achieve optimal settings and deliver precise images.
Wideband Transducer compatible with ClearChirp™ Fishfinder
The wideband transducers for ClearChirp™ can be selected from TD320/TD340/TD361/TD380.
The frequencies are 90kHz–140kHz for mid-chirp, 38kHz–70kHz for low-chirp, and 130kHz–220kHz for high-chirp.
●Wideband Transducers for Chirp●

HDX-10C also features Wideband mode! You can select frequencies.
In wideband mode, by connecting a wideband transducer, frequencies can be selected in 5kHz steps for low-chirp and 10kHz steps for mid/high-chirp. By selecting and changing the optimal frequency according to the fishing ground and target species, it is also effective in reducing interference and noise from other vessels' fish finders.

【NEW】White Line Function Equipped
Highlights the boundary of the seabed with a white line.
The display level can be adjusted, allowing you to fine-tune how the seabed appears to suit your fishing grounds and target species.
This makes it easier to distinguish between fish and the seabed, ideal for fishing targeting schools of fish near the bottom.
*Scheduled to be available from shipments in April 2026 onwards

Depth Mapping® Function Equipped!

【NEW】Depth Mapping® function storage capacity increased 10x
The storage capacity has been increased tenfold, allowing for 1000 hours of data to be recorded internally.
This allows you to save even more of "your own points" and further enhances the enjoyment of fishing.
*Planned to be installed in products shipped from April 2026
【Depth Mapping® PV】
【NEW】GPS Buoy Display Function
By inputting data from a GPS buoy receiver, you can display the position of the GPS buoy.
We do not sell GPS buoys, so you will need to prepare them separately.
Please contact your nearest dealer for more information.
*Scheduled to be supported from products shipped in April 2026
*An optional NMEA input/output cable (XC-109H) is required to use the GPS buoy display function.
*Up to 10 targets.
*GPS buoy trails disappear when the power is turned off.

Smartphone/Tablet Support
The image displayed on the main unit can be projected onto a smartphone or tablet.
Basic operations can also be performed from a smartphone or tablet.

For detailed information on compatible devices (smartphones/tablets) that have been tested for connection with the HDX series, please see below.
Please note that operation may become unstable depending on communication conditions.
For iOS, it may not work depending on the OS version and Safari version.
Large capacity memory
Compared to conventional models, it has a large capacity for storing track lines and marks.
Smooth map drawing
Compared to conventional models, map drawing is now smoother. *GPS reception frequency: 5 times/1 second
USB port for data saving
The main unit is equipped with a USB port, so you can transfer and save mark data and images from the main unit to a commercially available USB memory (32GB or less) without the need for an optional memory card.
*USB memory is not included.
*The HDX-10C is equipped with a USB (Type-C) port. To connect with your existing USB memory (Type-A), please connect the included Type-C conversion cable for USB memory to the main unit.
*The USB memory that can be used with the HDX-10C is up to 32GB. We do not guarantee the operation of all USB memories. Some types may not operate normally.
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 now includes a size display feature for the popular fish character function.
You can determine the size from 1 to 99, and we've also added a one-touch "Show/Hide" feature to instantly check reactions in real-time video, as well as a dual-screen display with the regular screen.
*This function is only active in fish mark mode. It can also be used within a 100m range.
*The numerical values for the size display may vary due to various factors. Please consider them as reference values only.
● Fish Depth Display
We've added a display of the height from the seabed and the depth from the sea surface (unit: m) to the fish character display.
*This function is only active in fish mark mode. It can also be used within a 100m range.
*The numerical values for the depth display may vary due to various factors. Please consider them as reference values only.
● Dual Screen Display of the Same Frequency
You can split the fishfinder image of the same frequency into two screens and adjust the sensitivity of each.
By comparing the two screens, you can set the optimal sensitivity.
● Full-Screen Sensitivity Adjustment
With conventional fishfinders, changing the sensitivity would apply from that point onwards, but with digital fishfinders, it is now possible to change the sensitivity on the screen (past records).
With this function, you can adjust the sensitivity 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 has a very high resolution of 800x600 dots, ensuring fine details and characters are clearly visible.
Additionally, the adoption of a high-brightness LCD (1000 candelas) provides excellent visibility in bright environments, such as under direct sunlight.
Furthermore, the use of a bonded LCD improves screen 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 installation location and method.
Additionally, the HDX-10C supports monitor connection (no modification fee required!), allowing the same screen to be displayed at remote locations on the vessel.
