Dave Canterbury from Duel Survivor was fired from the show after it was found out he’d completely lied about his military/survival experience!

In September 2011, Dave Canterbury was fired as the host of the Duel Survivor TV show on Discovery Channel. Canterbury had originally said it was for family and business reasons that he decided to leave the show in a statement in April 2012. Actually, it was finally released that he’d lied about his military and survival experience that landed him the job. He claimed he had survival expertise for 20 years before getting the job on Duel Survivor.

Records showed that he was a factory worker in Ohio up until the year before he got the job with Discovery Channel. He had been in the military in their version of a SWAT team in the Army for six years. He was never a Ranger, Survival Scout, or had any Airborne Training as he had claimed. Neither had he been to Grenada or South America as he had claimed. He’d only been to Korea as an “ID Badge Clerk.
