The NiTek Duo Docking Station and accompanying NiTekLogic software is used to download dives to a PC running Microsoft Windows XP, 2000, or 98 Second Edition. It includes the docking station, USB data cable, and CD containing NiTekLogic software. The NiTekLogic logbook program displays information about each stored dive and allows divers to add information to each dive or dives that were done without the computer. The NiTek Duo Docking Station allows divers to connect to Divers Alert Network (DAN) studies by uploading dive log data directly to DAN with a single button.
