Shot a match with mine this last week and its definitely a cool toy, but I've got a few suggestions for software/usability I hope don't fall on deaf ears.
1-Increase the number of targets to program from 5 to 10, 6 targets on a given stage is not uncommon and 10 is pretty standard in larger matches
2-Add an option to link the target's wind bearing to the first target. Its rare that I've come across targets more than a few degrees difference in bearing on the same stage, while I realize this may trade a bit of scientific accuracy I think the expediency gained in a competitive environment will be worth it. The problem isn't so much having all targets show the same bearing, as it is that you have to manually tell every target what the bearing to the target is, and that is tedious and time consuming. I would rather enable an option to link them all so if I set the bearing on one target, or in a general direction, all the active targets then receive the same bearing information without my having to manually tell each one the same thing. You can see why that might be helpful, especially if you listen to suggestion number 1!
