Unfortunately within our remit of search and rescue we have the need to search water. This in itself needs a slow and methodical approach. In order to remove an area from our search we need to be positive that a missing person is not within an area. Having the facility to be able to look below the surface will allow us to either concentrate on a specific area or discount it from a potential area. In the unfortunate event we do discover our missing person we can liaise with the police and arrange for recovery to take place and allow a family or friends or their community come to terms with the very sad reality.
