The blue oxygen tank came with the Second Series Q Force Aquatrooper, the Stingray and the Q Force Battle Gear. It also came with the German figure ‘Hai’ and the German vehicle ‘Tiefengleiter.’

The pack connects to the figures body with a strap and then the mask slides over the pack and face area. From a side angle the pack resembles the shape of a Shark (the figure is called Shark).
