Developed In-house! Equipped with HONDEX ClearChirp™ Fish Finder!
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 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 are able to achieve optimal settings and deliver precise images.
Wideband Transducers Compatible with ClearChirp™ Fish Finder
You can choose from TD320/TD340/TD361/TD380 for ClearChirp™ wideband transducers.
The frequencies are 90kHz to 140kHz for mid-chirp, 38kHz to 70kHz for low-chirp, and 130kHz to 220kHz for high-chirp.
●Chirp Wideband Transducers●

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. 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】Equipped with White Line Function
Highlights the boundary of the seabed with a white line.
The display level can be set, so you can adjust how the seabed appears to suit your fishing spot and target.
It makes it easier to distinguish between fish and the seabed, making it ideal for fishing for schools of fish near the bottom.
*Scheduled to be supported from shipments starting April 2026

Equipped with Depth Mapping® Function!

【NEW】Depth Mapping® Function Storage Capacity Increased 10-fold
Storage capacity has been increased 10-fold compared to previous models, allowing 1000 hours of data to be recorded internally.
You can now save even more of your "own points," further expanding your fishing enjoyment.
*Scheduled to be installed from shipments starting 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.
We do not sell GPS buoys, so customers need to prepare them separately.
For more details, please contact your nearest dealer.
*Scheduled to be supported for shipments from 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 Compatible
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.
*Operation may become unstable due to communication conditions.
*For iOS, it may not operate depending on the OS version and Safari version.
Large capacity storage memory
Compared to conventional models, the memory capacity for tracks and marks is larger.
Smooth map drawing
Compared to conventional models, smoother map drawing is now possible. *GPS reception frequency: 5 times/1 second
USB port for data saving
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 memory (32GB or less) without the need for an optional memory card.
*USB memory is not included.
*Operation of all USB memories is not guaranteed. Some types may not operate normally.
Main fishfinder functions of HDX-12C
The HDX-12C is equipped with a variety of functions unique to HONDEX fishfinders.
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 also use a one-touch "display/hide" function and a two-screen display with the normal screen to instantly check reactions in actual images.
*This function is only valid in fish mark mode. It can also be used within a 100m range.
*The numerical values for size display may have errors due to various factors. Please consider them as reference values only.
Fish Depth Display
The fish character display now includes the height from the seabed and the depth from the sea surface (unit: m).
*This function is only valid in fish mark mode. It can also be used within a 100m range.
*The numerical values for depth display may have errors due to various factors. Please consider them as reference values only.
Same Frequency Two-Screen Display
The fishfinder images 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 optimal sensitivity.
Full Screen Sensitivity Adjustment
With previous fish finders, changing the sensitivity would take effect from that point on, but 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 adopted
The display has a very high resolution of 800x600 dots, so even small reactions and characters are clearly visible.
In addition, the adoption of a high-brightness LCD (1000 candela) ensures excellent visibility even in bright places such as direct sunlight.
Furthermore, the bonded LCD improves 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 cost required), allowing the same screen to be displayed in a remote location on the ship.
