Contacting Kestrel yields them to tell you to call Horus Vision, and Horus Vision will completely ignore you (even when you start out VERY polite).
Kestrel also does not have current software to support Windows 7, so if you plan on hooking up you device to a laptop for programming or reading data in the field, forget about it.
Horus Vision is supposed to have a software for the 4500NV ATRAG with Blue Tooth (and I assume serial coms), but this "Gun Library" software does not exist [though it's listed in the manual for the unit].
Basically, I would consider avoiding this product if you plan on using it for more than 5 gun and/or proprogrammed batches of ammo. (I chrono all batches of ammo... So using 5 buttons on the 4500NV isn't really helpful.)
According to the documention, the Gun Library software is supposed to support MORE than 5 guns... (50)

Primarily initially replaced by the hand held GPS and now even by the new “smart” cell phones that include GPS, electronic compass – even real time imaging on aerial maps! Once the friend of every hunter and now the companion of few. It is not glamorous or glitzy, that is for sure… no bells and no whistles. Aaaaah, but let’s not rush to forget our...
