●Accessories: Main unit & stand, power cord, transducer, hard cover
●Equipped with wideband mode
Developed in-house! Equipped with HONDEX ClearChirp™ Fish Finder!
General fish finders output sound waves into the sea at a single frequency and display the received signals as images.
In contrast, the chirp method outputs 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●



Also, 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 can achieve optimal settings and realize precise images.
Wideband transducer compatible with ClearChirp™ fish finders
Wideband transducers for ClearChirp™ are available from 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.
●Chirp Wideband Transducer●

HDX-12C 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 and 10kHz steps for mid and high. By selecting and changing the optimal frequency according to the fishing ground and fish species, it is also effective in reducing interference and noise from other boats' fish finders.

【NEW】White Line Function Installed
Highlights the seabed boundary with a white line.
The display level can be adjusted, allowing you to customize the seabed visibility according to the fishing spot and target.
This makes it easier to distinguish between fish and the seabed, ideal for fishing for schools of fish near the bottom.
*Scheduled for release with shipments from April 2026

Equipped with Depth MappingⓇ function!

【NEW】Depth MappingⓇ function memory capacity increased tenfold
The memory capacity has been increased tenfold, allowing for 1000 hours of recording internally.
This allows you to save even more of "your own points", further expanding your fishing enjoyment.
*Scheduled to be included with shipments from April 2026
【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.
Please note that we do not sell GPS buoys, so you will need to prepare them separately.
For more details, please contact your nearest dealer.
*Scheduled to be supported from shipments 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 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.
*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, the memory capacity for tracks and marks is greatly increased.
Smooth Map Drawing
Compared to conventional models, smoother map drawing is now possible. *GPS reception frequency: 5 times/1 second
USB Port for Data Storage
Equipped with a USB port, allowing you to transfer and save mark data and images from the main unit to a commercially available USB memory stick (32GB or less) without the need for an optional memory card.
*USB memory stick is not included.
*Operation of all USB memory sticks is not guaranteed. Some types may not function properly.
Main Fishfinder Functions of HDX-12C
The HDX-12C is equipped with a variety of features unique to HONDEX fishfinders.
Fish Size Display
The digital series has added size display to the popular fish character function.
You can determine the size from 1 to 99, and to quickly check reactions etc. with actual images, it features a one-touch "display/hide" function and a two-screen display with the normal screen.
*This function is only effective in fish mark mode. It can also be used within a 100m range.
*The numerical value of the size display may have errors due to various factors. Please consider it as a reference value only.
Fish Depth Display
Added height from the seabed and depth from the sea surface display (unit: m) to the fish character display.
*This function is only effective in fish mark mode. It can also be used within a 100m range.
*The numerical value of the depth display may have errors due to various factors. Please consider it as a reference value only.
Dual Frequency Display
The fishfinder image of the same frequency can be split into 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
With previous fish finders, changing the sensitivity would take effect from that moment onwards. However, with digital fish finders, it is now possible to change the sensitivity on the screen (past records).
With this feature, you can adjust the sensitivity while viewing the entire screen (past records), allowing even beginners to manually set up clear images.
Bright screen with wide viewing angle & bonded LCD
The display has a very high resolution of 800x600 dots, so even fine reactions and text are clearly visible.
In addition, the use of a high-brightness LCD (1000 candela) provides excellent visibility even in bright places such as direct sunlight.
Furthermore, the use of a bonded LCD improves LCD visibility and prevents condensation.
Built-in GPS antenna, compatible with monitor connection system
The HDX-12C has a built-in GPS antenna. *When using the built-in antenna, reception may not be possible depending on the installation location and method.
In addition, the HDX-12C can be connected to a monitor (no modification costs required), allowing the same screen to be displayed at a distant location on the ship.
