He told Sky News that he often picks up very large animals on his sonar, some reaching the size of a car. “We get sonar contacts with things that are far bigger than any fish that should live in this body of water,” he said. “We only get one or two decent sightings a year.” He believes that the large catfish can explain these sonar readings. CNN couldn’t reach Feltham on Friday, but on his website, he chronicles his journey in search of the mythical monster. In 1991, he sold his home and left his job and girlfriend in pursuit of Nessie. He lives in what he describes as an ex-mobile library van at Dores Beach on Loch Ness. He searches for Nessie full-time but makes and sells figurines of the creature to tourists on the side to supplement his income.
