Abstract
An audible signalling system is provided for us by divers or the like to provide a relatively loud audible signal which can be used to indicate diver position, to signal distress, etc. The preferred system utilizes an air horn carried by the diver and adapted for connection to a pressurized air supply carried by the diver for breathing purposes. When the air horn is connected to the air supply, the horn can be operated to produce a loud audio signal of substantial range which can be heard relatively easily over ambient noise such as wind, water and/or boat noise. In one form, a sonic oscillator for use in underwater signalling is also included.
