Rethinking Hydrography

Our Company
Unabara is a vertically integrated manufacturer of game-changing tools for shallow water hydrography and oceanography. Combining our competencies in underwater acoustics and piezo-ceramics with ASIC and MEMS semiconductor technology, we are changing how surveyors obtain and process data.

Our Name
Our corporate name, Unabara, has its origin in the 8th century Japanese word which denotes the ocean, the sea, the deep, the abyss.

Our Products
During 2016/2017, we will introduce a full complement of user-centered hydrographic tools. Please visit www.hydrobar.info to explore our first product in the series, a truly unique, easy to use, instrument for rapidly and most accurately performing bar check calibration of echo sounders and obtaining sound velocity profiles.

Our HydroBook single-beam hydrographic echo sounder offers such features as sub-centimeter depth resolution, 0.10 meter (4 inch) minimum depth of operation, and user-selectable frequency & transducer beamwidths. View these and other features never before available in a shallow water hydrographic echo sounder at www.hydrobook.info.
