I was very disappointed with this product. Spent nearly $400 on this unit. I set the date and time and the unit records a date two years in the past. Tried to follow the instructions to download the driver and install Prologue onto my MacBook. Software doesn't recognize the altimeter when connected. Reading through jumps on the device is tedious yet software doesn't work. Altimeter reading are coming in about 800' lower than actual pull altitudes. Pulled today between 3-4k consistently and in some case the altimeter was recording pull altitudes of 2,200 ft.
