"Le Rubis" is a sunken Saphir-class minelaying 216 ft. submarine which served in the French Navy and Free French Navy during the Second World War. It was commissioned in 1931 and struck from the list in 1949. It was sunk as a sonar target that year. It is located in 41 m (135 ft) of water between Cavalaire and Saint-Tropez in the Mediterranean.

An intriguing free diving video down to the Rubis. NOX Diving uses an interesting technique, overweighting to increase his speed of descent and then dropping his weight belt to a buoyed recovery line once at depth to ease his ascent. In both ways reducing exertion and increasing bottom time. He uses the GoPro "back camera" monopod technique for filming which I am fond of myself, placing the diver into the image field.
