First purchased in 1990, RESON's SeaBat 8101 has now seen more than 15 years continuous service with EMC Inc., one of US's leading marine survey companies.

Mark Mattox President of EMC said "We are using the SeaBat primarily on US Army Corps of Engineers and Na-tional Oceanic and Atmospheric Administration (NOAA) contracts. The Corps is responsible for all inland water-ways and navigation channels in the US. We typically use SeaBat on a monthly basis for channel and bank surveys in rivers and harbors from the Mississippi river to South Florida. These surveys are generally for navigation and dredging projects. We have found the SeaBat to be very reliable with limited repairs neces-sary."

He went on to say "The SeaBat 8101 is capable of high accuracy depth measurements over a swath of the bottom equal to five times the water depth. It is a highly accurate multi-beam system that uses one hundred and forty transducers, mounted in a two hundred and ten degree array, to survey the sea floor. Full coverage one-half foot plus accuracy are achieved with the 8101 system. This is an economical system with unlimited potential for many hydrographic and other applications."

Finally he added "The 8101 continues to meet and exceed the performance test standards set by the US Army Corps of Engineers and we perform these tests prior to every survey."
