Robot finds Nessie film prop at the bottom of Loch Ness

Fast-forward to 2016 and Kongsberg Maritime, a specialist in underwater positioning technology, has rediscovered the prop. The company was scanning with MUNIN, one of its many autonomous underwater robots, when it recorded an image of the 10 meter long replica. MUNIN uses a variety of sonar and camera equipment to produce high-resolution datasets at a depth of up to 1,500 meters. "Nessie" came up in one of its scans and Adrian Shine, who leads The Loch Ness Project, was able to confirm that it's the prop from The Private Life of Sherlock Holmes. "We can confidently say this is the model because of where it was found, the shape -- there is the neck and no humps -- and from the measurements," he told BBC News.
