Well, after boing disapointed with the first one anf vowing never to purchase a MSM device again...I borrowed a Nomad in April and can honestly say that its a vast improvement over the original.
The laster pointer I got sent still had issues even tho I tried to calibrate it but I was sent out another one within a couple of weeks.
You don't need a polar scope, the laser is accurate enough.
In addition to the ball head I'd recommend the wedge and a V plate. That's reallt all you need.
A couple of improments could include having the arca plate mountable in both directions and possibly including a larger gap on the arca bracket at the bottom for anyone using a Gitzo...if you use Gitzo and arca plates not designed for Gitzo then you know the frustration.
Otherwise a nicer product than the original.
