I expect to be assembling my Edge within four weeks so it's time to move into a weather gauge/wind meter gadget, tablet, and ballistics program. Maybe both interior and exterior varieties on the latter. Examples: Kestrel's Horus ATrag, Shooter, Exbal? Android or Ipad, etc. I'm liking the Bluetooth connectivity concept; I use Bluetooth technology all the time and its proven comfortable and consistent. As always I appreciate your counsel, thank you.
