First off I love my Altitrack and would recommend it to anyone who wants an analog display with digital accuracy and a computer. I would just like to inform potential buyers about a known issue with negative offset entry. If you are jumping into an elevation which is higher than your take off altitude be advised you cannot enter a Negative Offset into the device. Example - our DZ is 490ft higher than our takeoff altitude, so I would need to adjust minus 490 on a regular altimeter. According to L&B this is a known issue and they are working on an upgrade to be released around August 2007. The suggested workaround; "The way you should do is manually adjusting the Altitrack to ”0” when you climb in the plane and pass the altitude of the DZ where you are going to land.". cheers, Paul
