Reson multibeam trials

The following photos show our first installation and testing of the equipment. The system was installed on a local tug boat New Ross One using a heavy mounting device made of 12-inch steel piping in order to test the deep water SeaBat 8160 array. We then replaced the deep water array with the high frequency Sea Bat 8101 sonar. This configuration was used to carry out surveys within Swansea Bay and off the south Gower coastline, with some spectacular results.

We would like to express our thanks to John from Reson and Norman from GSE Rentals for help with installing the electronics. G & J Engineering (Cardiff) did a great job of fabricating the mounting pole for us and then installing it on the vessel. Dave Hoskins of Cardiff Commercial Boats is thanked especially for his professional seamanship which ensured that some high-quality data were collected in our first field season.
