<p>The device for the automatic adjusting, according to the pressure, of the length of the connection rope between a buoy and a skin-diver comprises a means (1) for winding and unwinding a rope (C) for the connection between a floating buoy and an immersed skin-diver, for determining the automatic adjusting of its length following to the indications supplied by a sensor (6) for the taking of the pressure, provided on the skin-diver himself or on his spear gun or on any other housing. The information about the reached depth is transmitted to said means (1) by means of an emitter (4) of acoustic waves with a relative receiver (5) or, in a variant, by means of electric impulses through an electric cable (8) for the connection between a skin-diver and a buoy (B).</p> |
