●Accessories: Unit & mount, power cord, transducer, hard cover
●Equipped with wideband mode
Exclusively developed! Equipped with HONDEX Clear CHIRP™ Fish Finder!
Conventional fish finders emit sound waves into the sea at a single frequency and display the received signals as images.
In contrast, CHIRP fish finders emit sound waves while gradually changing the frequency and display the received signals as images after special processing.
This significantly improves resolution and allows fish to be clearly displayed.
●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 produce highly detailed images.
Wideband Transducer for Clear CHIRP™ Fish Finders
You can choose from TD320/TD340/TD361/TD380 for Clear CHIRP™ 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 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 frequencies and 10kHz steps for mid and high frequencies. By selecting and changing the optimal frequency according to the fishing ground and target fish species, it is also effective in reducing interference from other ships' fish finders and noise.

【NEW】Equipped with White Line function
Highlights the seabed boundary with a white line.
The display level can be set, so you can adjust how the seabed appears according to the fishing spot and target.
It makes it easy to distinguish between fish and the seabed, making it ideal for fishing for schools of fish near the bottom.
*Scheduled to be available from shipments in April 2026

Equipped with Depth Mapping® function!

【NEW】Depth Mapping® function storage capacity increased tenfold
Storage capacity has increased tenfold, allowing for 1000 hours of recording internally.
You can now save even more "personal spots," further enhancing your fishing enjoyment.
*Scheduled to be implemented from shipments in 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.
For details, please contact your nearest dealer.
*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.
*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 projected onto a smartphone or tablet.
Basic operations can also be performed from a smartphone or tablet.
Operation may be unstable due to communication conditions.
For iOS, it may not operate depending on the OS version and Safari version.
Large Capacity Memory
Compared to conventional models, track and mark storage capacity has been greatly increased.
Smooth Map Drawing
Compared to conventional models, smoother map drawing is now possible. *GPS reception frequency: 5 times/second
USB Port for Data Storage
Equipped with a USB port, 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.
*Operation is not guaranteed for all USB memory devices. Some types may not function properly.
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 adds a size display to the popular fish character function.
You can determine the size from 1 to 99, and to instantly check reactions and other information on the actual image, a one-touch "display/hide" function and a two-screen display with the normal screen have been adopted.
*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 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 of the depth display may have errors due to various factors. Please consider them as reference values only.
Dual Frequency Display
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 previous fish finders, sensitivity changed from the moment it was adjusted, but with digital fish finders, it is now possible to change the sensitivity on the screen (past records).
This feature allows sensitivity adjustment while viewing the entire screen (past records), enabling even beginners to manually set up clear images.
Bright screen with wide viewing angle & bonded LCD
The display has a very high resolution of 800 x 600 dots, clearly showing even subtle responses and text.
Additionally, the adoption of a high-brightness LCD (1000 candela) ensures excellent visibility even in bright conditions 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 mounting location and method.
Additionally, the HDX-12C can be connected to a monitor (no modification costs required), allowing the same screen to be displayed in remote locations on the boat.
