    2 introduction the datamax sport was designed to be extremely easy to use and under- stand. This owner’s guide is divided into five sections designed to make it easy to learn how to use the “sport.” the first two sections will show you how it performs in most diving situations. Section three describ...

    5 if you have not entered decompression, a safety stop made between 15-20 feet is strongly recommended as a standard procedure before completing your ascent. Many divers do this to provide a wider zone of caution from the no- decompression limit. The tissue loading bar graph gives a visual represen-...
