PORTABLE DANGER DEVICE

摘要

Portable device practicable for submarine applications and usable in case of urgent need. The invention relates to a portable sound-and light-emitting device which can be fitted to any point of the diver's body as well as to all-type diving equipment. In emergency, the device emits by pressure of the button provided sound and constant beam of light which is visible by the other divers into the water or at the surface thereof. Likewise, the device in question is provided with a security system which emits sound and light signals to keep a couple of divers from wandering.
