●Equipped with wideband mode
Developed In-house! Equipped with HONDEX ClearChirp™ Fish Finder!
Conventional fish finders emit sound waves into the sea at a single frequency and display the received signals as images.
In contrast, the chirp method emits sound waves while gradually changing the frequency and processes the received signals specially for image display.
This significantly improves resolution, allowing fish to be displayed vividly.
●Chirp Image Examples●



Moreover, to achieve this chirp technology, a dedicated wideband transducer capable of emitting 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 highly detailed images.
Wideband Transducer compatible with ClearChirp™ Fish Finder
You can choose a wideband transducer for ClearChirp™ 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 a wideband mode! You can select the frequency.
In wideband mode, by connecting a wideband transducer, you can select frequencies in 5kHz steps for low and 10kHz steps for mid/high. Selecting and changing the optimal frequency according to the fishing ground and fish species is also effective in reducing interference and noise from other vessels' fish finders.

【NEW】White Line Feature Included
Emphasizes seabed boundaries with a white line.
The display level can be adjusted, allowing you to fine-tune how the seabed appears to suit your fishing spot and target.
It makes it easier to distinguish between fish and the seabed, ideal for fishing aiming at schools of fish near the bottom.
*Scheduled to be supported from products shipped in April 2026.

Depth Mapping® Feature Included!

【NEW】Depth Mapping® function storage capacity increased 10x
Storage capacity has been increased tenfold, allowing for 1000 hours of data to be recorded internally.
This allows for more "personal points" to be saved, further expanding the enjoyment of fishing.
*Scheduled to be installed on units shipped from April 2026 onwards
【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 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.
*Up to 10 targets.
*GPS buoy tracks disappear when the power is turned off.

Smartphone/Tablet Compatibility
The image displayed on the main unit can be mirrored to 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 confirmed to work with the HDX series, please refer to the following.
*Depending on communication conditions, operation may become unstable.
*For iOS, it may not work depending on the OS version and Safari version.
Large capacity memory
Compared to conventional models, the number of memory points for tracks and marks is greatly increased.
Smooth Map Rendering
Compared to conventional models, map rendering is now smoother. *GPS reception rate: 5 times/1 second
USB Port for Data Storage
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 USB memory Type-C conversion cable to the main unit.
*The maximum supported USB memory for the HDX-10C is 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 unique HONDEX fishfinder functions.
● Fish size display
The digital series adds size display to the popular fish character function.
It can be determined by a size from 1 to 99, and a one-touch "display/hide" function and a two-screen display with the normal screen are adopted so that the reaction can be confirmed instantly with the actual image.
* This function is only valid in fish mark mode. Also, it can be used within the 100m range.
* The numerical value of the size display may have an error due to various factors. Please consider it as a reference value.
● Fish depth display
The fish character display has been added with the height from the seabed and the depth from the sea level (unit: m).
* This function is only valid in fish mark mode. Also, it can be used within the 100m range.
* The numerical value of the depth display may have an error due to various factors. Please consider it as a reference value.
● Same frequency two-screen display
The fish finder image of the same frequency can be divided into two screens, and the sensitivity of each can be adjusted.
By comparing the two screens, you can set the most optimal sensitivity.
● Full-screen sensitivity adjustment
With conventional fish finders, the sensitivity changed from that point when it was changed, but with digital fish finders, it is now possible to change the sensitivity on the screen (past records).
With this function, you can adjust the sensitivity while looking at the entire screen (past records), so even beginners can manually set a clear image.
Bright screen with wide viewing angle & bonded LCD adopted
The display unit has a very high resolution of 800 x 600 dots, allowing even fine reactions and characters to be seen clearly.
In addition, the use of a high-brightness LCD (1000 candelas) provides excellent visibility in bright places such as direct sunlight.
Furthermore, the use of a bonded LCD improves LCD 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, it may not be able to receive depending on the mounting location and method.
In addition, the HDX-10C can be connected to a monitor (no modification costs required!), allowing the same screen to be displayed even in remote locations on the ship.
