The 44-year-old marksman from Belarus already had two bronze medals to show for his previous five appearances at the Olympic Games.
Martynov, dubbed 'the man who does not smile', outclassed the rest of the field at the Royal Artillery Barracks in Woolwich to get his hands on gold.
He scored perfect 600 in qualifying and increased his lead in the final, not missing a single bullseye and nailing one perfect 10.9, to set a new world record of 705.5.
Martynov was a massive 4.3 points ahead of Belgium's Lionel Cox, who took silver with Rajmond Debevec of Slovenia winning bronze.
