HONDEX echosounders and GPS plotters are suitable for a wide range of commercial fishing industries. 

Hondex transducers, sounders, and GPS products are deisgned and produced in house by HONDA corporation in Japan.

  • All Hondex units are designed and constructed in Japan

  • All transducers are BLT design and offer the best matching to Hondex sounders

  • Cost effective transducer / sounder combination

  • VGA (800x600) output from HDX-121 / HE-2910 allows any number of remote displays at any size

  • HDX-121 & HE-2910 offers 800x600 resolution, sounder rewind function, Hardness output, and hardness/depth contour mapping all from the one unit

  • Hardness (Roxann format) output can be used with OLEX and compatible plotting systems

  • Hardness tracking from within unit allows stand alone plotter/hardness mapping (HDX-121 only)

  • Transducers available in power levels from 600w to 5KW in frequencies from 28Khz to 400Khz



HDX-121 is a new designed plotter/sounder combination unit from Hondex. Running on Linux technology, this combination unit is fast, reliable, and produces amazing sounder images while mapping the seafloor on the inbuilt plotter.

This 12.1" unit has an inbuilt GPS, VGA output, 800x600 resolution, 1-2KW sounder at 50/200Khz, offers sounder 'rewind' function, on screen hardness graph, and can record both the seafloor and hardness contours all from within the unit.

The HDX-121 has a CMAP SD card reader slot; any CMAP SD chart card can be used. The unit has multiple NMEA input/output ports, can accept a wide range of NMEA data, and can output many different formats including hardness data (if required) for external plotting.

This unit can map hardness and depth contours directly onto the inbuilt plotter, and colour them accordingly. Seafloor data can then be saved onto either an SD card, or a standard USB device. 


Hondex Transducers

Hondex manufacture their own cost effective transducers from the element all the way up to the housing, in house. All marine transducers are BLT (Bolt Clamped Langevin) design, offering superior frequency stability, bandwidth, & durability even under high amplitude signals.

Frequency and power range from a tiny 350W at 200Khz, all the way up to 5KW at 28Khz. Hondex transducers are available in a large range of configurations ranging from Dual frequency 50/200Khz 1/2/3KW to specialised frequencies, and even tri-resonant designs, some resonant examples are:

38-75Khz in power ranges 1.5KW-5KW; 32-40Khz @ 2.5/3KW; 36-65 @ 3/5KW; 28-55 @ 3/5KW; 28-100 @ 3/5KW; and 28-55-100Khz @ 3/5KW.

Standard/conventional frequencies are also available which can be used with almost any manufacturers sounder - 28Khz @ 3/5KW; 50 @ 1.5/3KW; 200 @ 1/1.5/3KW & 50/200Khz @ 1/3/5KW. There are varying beam widths available, depending upon frequency and power selection.
