Hi everyone, I am opposed to the use of wrist‑mounted dive computers in commercial diving. However, I do wonder whether it might be worthwhile for commercial divers to wear a small electronic sensor of this type. The device cannot be read underwater, but it records and stores all dive information, which can later be downloaded to a computer. Several inshore divers here in Belgium have been using it for many years, and personally I find this kind of logging device very useful. In the event of a dispute, it can provide a great deal of valuable information about any problematic dives.
