●Equipped with Wideband Mode
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 specially to display images.
This significantly improves resolution and allows fish to be displayed more clearly.
●Chirp Image Examples●



To realize this chirp technology, a dedicated wideband transducer capable of transmitting 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.
Wideband Transducer compatible with ClearChirp™ Fishfinder
For ClearChirp™, you can choose from wideband transducers TD320/TD340/TD361/TD380.
The frequency ranges are 90kHz–140kHz for mid-chirp, 38kHz–70kHz for low-chirp, and 130kHz–220kHz for high-chirp.
●Chirp Wideband Transducer●

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

【NEW】Equipped with White Line Function
Emphasizes the seabed boundary 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, ideal for fishing for schools of fish near the bottom.
*Scheduled to be compatible with shipments from April 2026 onwards

Equipped with Depth Mapping® function!

【NEW】Depth Mapping®️ memory capacity increased 10x
The memory capacity has been increased 10-fold, allowing for up to 1000 hours of data to be recorded internally.
This allows you to save even more of your "personal spots," further expanding your fishing enjoyment.
*Scheduled 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 purchase one separately.
Please contact your nearest dealer for details.
*Scheduled for support from products shipped from April 2026.
*An optional NMEA input/output cable (XC-109H) is required to use the GPS buoy display function.
*Up to 10 targets are supported.
*GPS buoy tracks disappear when the power is turned off.

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

For detailed information on compatible devices (smartphones/tablets) confirmed to work with the HDX series, please see below.
*Operation may be 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, the number of tracks and marks that can be stored is greatly increased.
Smooth Map Rendering
Compared to conventional models, map rendering is now smoother. *GPS reception frequency: 5 times/second
USB terminal for data saving
Equipped with a USB terminal, the unit 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.
*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 HDX-10C is up to 32GB. Operation is not guaranteed for all USB memories. Some types may not operate normally.
Main features of HDX-10C
The HDX-10C is equipped with various features unique to HONDEX fish finders.
● Fish size display
In the digital series, we have added a size display to the popular fish character function.
You can determine the size from 1 to 99, and also quickly check the reaction with actual video, with a "display/hide" one-touch function and a dual-screen display with the normal screen.
* This function is only valid in fish mark mode. It can also be used within a 100m range.
* The numerical values of the size display may have errors due to various factors. Please consider them as reference values.
● Fish depth display
We have added the height from the seabed and the depth from the sea surface (unit: m) to the fish character display.
* This function is only valid in fish mark mode. It can also be used within a 100m range.
* The numerical values of the depth display may have errors due to various factors. Please consider them as reference values.
● Dual-screen display of the same frequency
The fishfinder image of the same frequency can be split and displayed on two screens, and the sensitivity of each can be adjusted.
By comparing the two screens, you can set the optimal sensitivity.
● Full-screen sensitivity adjustment
In conventional fishfinders, changing the sensitivity meant it changed from that point onward, but with digital fishfinders, you can now change the sensitivity on the screen (past records).
With this function, you can adjust the sensitivity while viewing the entire screen (past records), so even beginners can manually set a clear image.
Wide viewing angle and bright screen & bonded LCD adopted
The display's dot count is 800x600, which is very high-definition, allowing even subtle reactions and text to be seen clearly.
In addition, the adoption of a high-brightness LCD (1000 candelas) provides excellent visibility in bright places such as direct sunlight.
Furthermore, the adoption of a bonded LCD improves LCD visibility and prevents condensation.
Built-in GPS antenna, compatible with monitor connection system
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.
In addition, the HDX-10C can be connected to a monitor (no modification costs!), allowing the same screen to be displayed in remote locations on the ship.
