Rear tilting is the most common technique used by divers who submerge themselves from a light, low, pneumatic-type boat. Once fully equipped with a diving mask on his face and a regulator in his mouth, the diver sits on the edge of the boat with his back towards the sea, placing his bottle above the water. He then tips backward, holding his mask and regulator with one hand and the bottom of his empty or little inflated stabilization vest with the other.
