During the final phase of testing we put our "computer geek" test divers to the task of using and evaluating the hardware and software that allow you to transfer dive data from your dive computer to your personal computer. In addition to being highly experienced recreational divers, these test divers have backgrounds in software design and programming. Here are their observations:

Aeris Manta/Oceanic Geo Price: $99 The Geeks Said: The Oceanlog software was easy to install, but the USB drivers took a few retries. Once the program is installed, transferring data is easy and the "which dives to save" option lets you choose all, new or just the profiles you select. There is even a queries section that lets you search for all dives matching a certain criteria. User settings can be checked in the PC mode, saving time pushing buttons on the gauge.

Aeris Epic Complete/Oceanic Atom 2.0 Complete Price: Included in the complete package. The Geeks Said: Very easy to download data once you install the software and drivers. The graphic display of dive data is minimal but there are plenty of options for adding details to complete your log of the dive day. Air consumption can be tracked from all three transmitters once you set the tank size and working pressure.

Cressi EDY Price: $150 The Geeks Said: The graphic display of dive data is exceptional and it's very easy to sort through all of the information. All data and graphs appear on one page, making for easy printing and organizing. The dive profiles are presented well and the tissue saturation bar graph is a nice addition.

Mares Nemo Sport Price: $150 The Geeks Said: The Mares Nemo Sport interface was not available at the time of testing.

Aeris Elite T3 Complete/Oceanic VT3 Complete Price: Included in the complete package. The Geeks Said: As with other Oceanic and Aeris download kits the ease of transferring data was impressive. Editing and importing features give you lots of options, and it's easy to add details to keep a logbook. Printing out dive data and graphs was easy. Settings are easy to check and adjust.

Mares Nemo Wide Price: $120 The Geeks Said: The PC interface was not available at the time of testing.

Sherwood Scuba Wisdom 2 Price: $80 The Geeks Said: The Wisdom 2 software allows nice editing features to complete your dive log. A simple graph is complemented by detailed profile information. The PC Interface uses a USB cable and free software can be downloaded from the Sherwood Scuba website.
