A simple upgrade from HDX-8C!
"I don't need complicated features, but I want to try ClearChirp™!" To meet such customer requests,
the HDX-8CII (from HDX-8C) has been made more affordable by removing Wi-Fi and 2-station functions.
All other functions are the same as the HDX-8C. Enjoy ClearChirp™ with the clear and sharp imagery of an SVGA LCD.
Independently developed! HONDEX ClearChirp™ compatible!
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 to display images.
This significantly improves resolution and allows fish to be displayed more clearly.
●Chirp Image Examples●



※These image examples are Low Chirp (left) / High Chirp (right)
Furthermore, to realize this chirp technology, a dedicated wideband transducer capable of outputting signals over a wide frequency range is required. By self-developing both the main unit and the transducer, we have achieved optimal settings and precise imaging.
Newly developed! Wideband transducer compatible with mid-chirp
The wideband transducer TD320, compatible with the HDX-8CII, is HONDEX's smallest wideband transducer ever. Its compact size allows for a wide range of installation options. The frequency for mid-chirp is 90-140kHz.
●Wideband Transducer for Mid-Chirp●

HDX-8CII also features a wideband mode! You can select the frequency.
In wideband mode, by connecting the wideband transducer TD320, you can select the frequency in 10kHz steps.
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 Function Included
Emphasizes 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 easier 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

Depth Mapping® function included!

[NEW] Depth Mapping® function's memory capacity increased tenfold
The memory capacity has been increased tenfold, allowing for 1000 hours of data to be recorded internally.
This allows you to save even more of your "own unique points," expanding your fishing enjoyment even further.
*Scheduled for installation in shipments from April 2026 onwards.
【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 you will need to purchase one separately.
Please contact your nearest dealer for more details.
*Planned to be supported from shipments in April 2026.
*The 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.

Data storage possible with USB port
The main unit is equipped with a USB port, allowing you to transfer and save mark data and images from the 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.
*HDX-8CII is equipped with a USB (Type-C) port. To connect with your existing USB memory stick (Type-A), please connect the included USB memory Type-C conversion cable to the main unit.
*USB memory sticks up to 32GB can be used with the HDX-8CII. Operation of all USB memory sticks is not guaranteed. Normal operation may not be possible depending on the type.
Main features of HDX-8CII
The HDX-8CII is equipped with various features unique to HONDEX fishfinders.
● Fish size display
The popular fish character function now displays fish size.
You can judge the size from 1 to 99, and also quickly check reactions with actual footage with the "display/hide" one-touch function, dual-screen display with the normal screen, and more.
*This function can 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.
*When the fish mark is ON, the CHIRP and 140kHz oscillation will automatically switch.
● Fish depth display
We have added distance from the seabed and distance from the surface (unit: m) to the fish character display.
*This function can 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.
● Dual-screen display of the same frequency
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 conventional fishfinders, the sensitivity changed from that point in time, but with digital fishfinders,
the sensitivity on the screen (past records) can now be changed.
With this function, you can adjust the sensitivity while viewing the entire screen (past records),
allowing even beginners to manually set clear images.
Bright screen with wide viewing angle & bonding LCD
The display dot count is 800 x 600, providing extremely high definition, allowing even subtle reactions and text to be seen clearly.
Additionally, the adoption of a high-brightness LCD (1000 candela) ensures excellent visibility even in bright environments such as direct sunlight.
Furthermore, the use of a bonded LCD improves screen visibility and prevents condensation.
Built-in GPS antenna, monitor connection system compatible
The HDX-8CII has a built-in GPS antenna. *When using the built-in antenna, reception may not be possible depending on the installation location and method.
The HDX-8CII can also be connected to a monitor (a modification fee of ¥55,000 is required separately), allowing the same screen to be displayed in remote locations on the boat.
