LCMM archaeologists tested the Blue View DF900-2250 on three sites in Lake Champlain. The first test subject was in shallow water, consisting of a simple board with raised lettering. The sonar system was then brought to a medium-depth shipwreck of a brick barge, Wreck GGG. Finally, the Blue View DF900-2250 was tested on the shallow-water wreck of the Champlain II, a nineteenth century steamboat.
After multiple dives on one test subject and two shipwrecks, LCMM archaeologists determined that the Blue View DF900-2250 Dual Frequency Miniature Multibeam Imaging System is not an effective tool to document the details of a shipwreck. However, it is an extremely useful system to provide a “big picture” image that could not be created by any other method at our disposal. Especially in low visibility environments, it also provided a safety mechanism by which we could immediately locate a separated diver.
