The 1970s

It's 1976. Three brothers, Jens, Claus, and Per Resen Steenstrup pool their expertise in advanced ultrasonic technology, and RESON A/S is born. At first, they focus on developing homogenisers, but before long their passion for the sea wins through, and by the end of the decade RESON is beginning to establish a strong presence in the market for underwater acoustic systems.

The 1980s

And exciting decade for RESON, the '80s see the production of RESON's first transducers and hydrophones, the company opens its first subsidiary, RESON Inc., in California. While the world celebrates the demolition of the Berlin Wall, RESON's first SeaBat multibeam sonar system carries out successful transoceanic cable route surveys.

1982 RESON develops its first series of transducers

1989 The first SeaBat Multibeam Echosounder system was developed.

The 1990s

A SeaBat is installed on an ROV for the first time at the beginning of the '90s – returning great results in deep, murky waters. A series of breakthroughs quickly follow. The SeaBat 9001 sets new standards in speed, accuracy and resolution; the SeaBat 8101 takes multibeam surveys down to 3,000 metres; and the SeaBats 8125 and 8160 make dynamically focused beams available to commercial surveyors for the first time.

1991 First high-performance SeaBat 9001 series to be ROV mounted

1999 Launch of the SeaBat 8000-series

The 21st century
RESON launches the SeaBat 8150 in 2001: RESON's first multibeam echosounder to cover the entire water column. Soon afterwards, RESON acquires Navitronic Systems, expanding the company portfolio with a range of market-leading singlebeam echosounders, sound velocity probes, and hydrographic software. The launch of the SeaBat 7125 soon follows, putting even greater performance and efficiency in the hands of underwater surveyors.
