SharkPoint v1 for Windows

SharkPoint for Windows is an inexpensive, easy to use, and full-featured diver's logbook. Designed for recreational divers the SharkPoint interface won't bother you with endless options and difficult to use features. You can enter as much information or as little as you like and output it easily to every own designed hardcopy.
The SharkPoint statistics and search tools make your electronic log much more useful that one kept on paper. You can easily find data and review trends in your diving to answer questions like "What depth do I most frequently dive to, and how long do I typically stay there?" or "Has my overall air consumption become better lately? By how much?".

SharkPoint v1 for Palm

Instead of bringing a laptop computer on your dive vacation, you simply take your Palm PDA to log all your dive information. If you have a handheld GPS (Global Positioning System) unit with compatible data output, you can even record the coordinates of your dive site to within a few tens of feet. At home, SharkPoint for Palm synchronizes to your PC for data backup. If you also have our PC software, you can load and edit the data in great detail. Statistics can be compiled and hard copy printouts of your data.
