As Eric mentioned, I spent some time with the BDX components throughout this last season, and we used the whole system on an Aoudad hunt this year, and it worked perfectly. Ran it through the precision rifle course as well, and it thus far has worked as advertised with both the 2400 and the 3k BDX, paired with or without the Kestrel 5700. Would love to try it with a Foretrex...but don't have the coin to get one of those at this time. But overall, it's been an impressive system!
Glasswise, its obviously no swaro, but it's definitely decent glass that does the job until after shooting light. Would love to see this up into the Tango 6 level glass, but as it is, it gets it done as well as our VX3i did or my HD5.
