If you are talking about the 5700, I've got one, it's not all that. If you only have a couple of rifles and spend the extra money for the profile loader so you can use your desktop, it's OK. The main issue I have with the Kestrel as a ballistic computer is the screen/user interface. It's pretty pathetic, given the small screen and limited keys it needs a LOT of button pushing and memorizing the menu structure to get to where you want to go. The solutions are fine, it's not the software, it's the device itself. It's fantastic for weather info, pretty bad for a computer. The upside is it's small, light and you need a weather station anyway.
