In service with customers world- wide since 1991 the RESON SeaBat range exemplifies these qualities as it continues to provide users with high quality data output and reliability over many years. “When selecting a sonar system it is not enough simply to look at price alone, we have systems that are still meeting our customers exacting requirements after more than 15 years continual service thus providing exceptional value for money,” said Michael Giese, Global Marketing Manager at RESON. "For example our customer EMC bought two SeaBat 9001s in 1990 then traded them in for a SeaBat 8101 in 1993 and they are still pro- viding excellent service today." EMC Inc. established in 1978, is a multidiscipline survey company encompassing the disciplines of Topographic, Hydrographic, Geophysical and Geotechnical Survey. Based in Greenwood, Mississippi they have carried out two million line miles of hydrographic survey data for both government and commercial customers in the US. “We are using the SeaBat primarily on US Army Corps of Engineers and National Oceanic and Atmospheric Administration (NOAA) contracts,” said Mark Mattox President of EMC. “The Corps is responsible for all inland waterways and navigation channels in the U.S. We typically use SeaBat on a monthly basis for chan- nel and bank surveys in rivers and harbors from the Mississippi river to South Florida. These surveys are gen- erally for navigation and dredging projects. We have found the SeaBat to be very reliable with limited repairs necessary. 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 accu- racy are achieved with the 8101 sys- tem. This is an economical system with unlimited potential for many hydrographic and other applica- tions.” 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." “When selecting a sonar system it is important to be sure that the system you select has the durability and reli- ability to keep performing well into the future, reducing maintenance costs and giving real value over the life-cycle of the system," said Giese. "With more than 225 sold units, SeaBat 8101 is the most used SeaBat sonar at the market. The only multi- beam sonar systems on the market that offer higher resolution and accu- racy are the SeaBat 8125 and 7125." RESON has recently introduced the SeaBat 7101 which is based on the success of SeaBat 8101, but with a number of new features. SeaBat 7101 can be upgraded from SeaBat 8101. The SeaBat Sonar Systems are used by a wide variety of customers in a diverse range of roles, including mili- tary mine hunting, harbor and coastal security, oil and gas exploration and dredging.
