I had no idea about this until I started doing som PDA questions in some other threads...seems like the Horus and Kestrel are teamed up and have a mil spec do it all firing solution...anyone run this combo and what dod you think of the whole setup...seems nice to have it all in one package, no seperate PDA to blutooth up ir to have to punch in mumbers ...seems like all you have to do is get a wind reading and a range to target and it gives ytou the firing solution in Mil or MOA drop and drift ...to include all the bells and whistles...and its mil spec....
