Device and method for simulating a drowning scenario

A manikin suitable for use in simulating a drowning scenario is disclosed. The manikin is of dimensions representing a human of specific age, sex, weight and build, and comprises jointed limbs. The density of the manikin as a whole, and the density of each limb and the torso of the manikin, is equivalent to the density of the human. The manikin further includes a means to track the movement of the manikin in a body of water, and also a means for simulating abdominal bloat, such as an inflatable bladder used in combination with a gas canister to inflate the bladder. The means to track the movement of the manikin may comprise an acoustic positioning system, an inertial measurement system or a global positioning system. The manikin may be with an epoxy resin/glass sphere mix of differing ratios depending on the densities required for each component.
