Simple update from HDX-8C!

“I don't need complex features, but I want to try ClearChirp™!” To meet such customer requests,
the HDX-8CII (from HDX-8C) has become more affordable by removing Wi-Fi and 2-station functions.
Other features are the same as the HDX-8C. Enjoy ClearChirp™ with the clear and vivid images of the SVGA LCD.

Our own development! HONDEX ClearChirp™ compatible!

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 for clearer imaging of fish.

●Chirp Image Examples●

※These image examples are Low Chirp (left) / High Chirp (right)

To implement this chirp technology, a dedicated wide-band transducer that can output 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.

Newly Developed! Wideband Transducer for Mid-Chirp

The TD320 wideband transducer compatible with the HDX-8CII is HONDEX's smallest wideband transducer ever. Its compact size allows for versatile installation. The frequency is mid-chirp: 90-140kHz.

●Wideband Transducer for Mid-Chirp●
TD320_説明2025

HDX-8CII also features Wideband Mode! You can select the frequency.

In wideband mode, by connecting the TD320 wideband transducer, frequencies can be selected in 10kHz steps.
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.

90-140kHz

【NEW】White Line Function Installed

Highlights the seabed boundary 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 targeting schools of fish near the bottom.
*Scheduled to be compatible with shipments from April 2026

Depth Mapping® Function Installed!

depthmap_2026

[NEW] Depth Mapping® function memory capacity increased 10-fold

The memory capacity has increased 10-fold, allowing the unit to record 1000 hours of data.
This allows you to save more of your "personal spots" and further expand your fishing enjoyment.
*Scheduled to be installed in products shipped from April 2026 onwards.

【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 them separately.
Please contact your nearest dealer for more details.
*Scheduled to be supported from products shipped in April 2026.
*The optional NMEA input/output cable (XC-109H) is required to use the GPS buoy display function.
*Up to 10 targets can be displayed.
*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.
*The HDX-8CII is equipped with a USB (Type-C) port. To connect 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. Some types may not operate correctly.

Main functions of HDX-8CII

The HDX-8CII is equipped with a variety of functions unique to HONDEX fish finders.

● Fish Size Display
The popular fish character function now displays fish size.
You can judge the size from 1 to 99, and there are one-touch "display/hide" functions and a two-screen display with the normal screen, allowing you to instantly check reactions with actual footage.
*This function can be used within the 100m range.
*The displayed size values may vary due to various factors. Please consider them as reference values only.
*When the fish mark is ON, the unit automatically switches to CHIRP and 140kHz oscillation.

● Fish Depth Display
The fish character display now includes the distance from the seabed and the distance from the water surface (unit: m).
*This function can be used within the 100m range.
*The displayed depth values may vary due to various factors. Please consider them as reference values only.

● Dual Screen Display with Same Frequency
This allows you to divide the fish finder 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
While previous fish finders changed sensitivity from that point onwards, digital fish finders now allow you to change the sensitivity on the screen (past records).
With this function, you can adjust the sensitivity while viewing the entire screen (past records), allowing even beginners to manually set clear images.

Wide viewing angle and bright screen & bonding LCD adopted

The display has a very high resolution of 800x600 dots, making even subtle reactions and characters clearly visible.
In addition, the adoption of a high-brightness LCD (1000 candelas) ensures excellent visibility in bright environments such as direct sunlight.
Furthermore, the bonding LCD improves 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.
Additionally, the HDX-8CII can 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.
