DESCRIZIONE
A flotation device that automatically inflates when contacted by water, but minimizes the risk of inadvertent inflation, includes an inflatable bladder (24) that is coupled to a water-activated inflator device (22) equipped with a water sensor (33). The water sensor is covered by a housing (66, 68) that prevents the flotation device from inflating inadvertently. The water sensor and housing are positioned on the upper back area of the wearer.
