Description of equipment :
Commercial diving equipment where the helmet linked of the surface with cable featuring two tons of tension strength. The cable carries a telephone line and two reserve pairs of wire for light, video signal and for any other use that may be necessary. There is a phone connection with the surface with full-time speaker function. Divers working under water are able to communicate with one another and their conversation can be recorded with a sound recorder. |
We also use video cameras where possible, water quality permitting. This allows us to make a video recording in addition to non-stop telephone communication, and it allows the customer to view what the diver does and how, and to convey instructions. We are able to transmit pictures of lesser quality even under poor water conditions, using special cameras, where the quality greatly depends on how clean the water is. |
