Your Certification Card proves you're a diver, but your log book proves your experience and frequency of diving. Be prepared to prove your experience when on vacation with your electronic log book. This kit features a Computer Interface USB Cable and is compatible with the TUSA IQ-750 and SCA-252/352 Element II Computer Modules. The kit allows the user to transfer Complete Log and Profile History from the Dive Computer to a Personal Computer or upload user settings to the computer. Share your diving experiences with your dive buddies and non-diving friends alike.
