In 2012, De Vos qualified for the first time for BDO World Darts Championship; this performance led to a wildcard for the Zuiderduin Masters.
Another remarkable achievement was throwing a nine-darter at the Denmark Open in 2008, a tournament in which he would lose the final against the Polish player Krzysztof Ratajski.
This win qualified him for the 2015 Grand Slam of Darts where he exited at the group stage with defeats to Robert Thornton and Terry Jenkins.
During two years with Tour card he was unable to qualify for any major events, playing only in 2021 and 2022 UK Open.
He did not play any major events in 2023 and appeared only in WDF tournaments and on MODUS Super Series, but stated that he wants to return to PDC and regain his Tour card.
