A lot of scuba divers have been in this situation and would have done anything to avoid it. This is exactly why SSI Computer Diver Specialty is such an important course. It is your chance to learn and understand diving computers.
Learning how to plan your dive with a dive table is extremely important. It is how you develop an understanding of the decompression theory. But in real life scuba divers do not use dive tables very often. Dive computers make scuba diving safer and easier if you know how to set and use it correctly. Bring dive computer & log book.
