The Deadman is often the only way of belaying on snow. When placed at the correct angle and then loaded, it will bury itself deeper, spreading the load dynamically over an area of snow. The final plate size has been chosen after extensive testing to optimise the balance between practicality and holding power. The lightening holes not only reduce the deadman's weight, but increase its drag coefficient in the snow and make it easier to convert into a snow shovel, by tying it to an ice axe.
