YES!! The shareware version is a full functioning version of the software. With the shareware version, you can do an unlimited number of Table 1 and Table 2 questions (first dive and surface interval).

I do want you to buy the full version of course, so on the shareware version, you will only be able to do 10 multiple dive, and or missing surface interval questions. Naturally, these are the hardest types of questions to master so I am hoping that after a taste of them, you want more and purchase the full version.

If not... That's OK too! If I helped you learn more about dive tables - I am happy for that as well. After all - I became a scuba instructor to help people enjoy diving - not for the money! But a lot of expense is involved in writing, printing, marketing, web page costs, etc, so if you do buy a full version from me... It is greatly appreciated!
