~sigh~ the cats and ferrets loved to play with the springy toy
Anywho, installation of the clip was painless to my TrackIR4 and after updating the software to v ...29 or 30 everything worked well.
I DID get a warning during installation that the software didn't pass the "icon test?" but ignorance is bliss so I'm happy.
How much better is it than the dot thingie on my visor? Much too early to tell yet, but it's at least as good. I'll let you know after the Sunday shoot'em up if I've noticed any improvement.

Old Vector clip

worked fine but needed frequent re-centering ... not as much as old TrackIR 1 with a single dot and it had a tendency to slide off and get chased by small furry animals. Better toy than a milk cap!

Looks cool, well ... cooler than the hat anyway. Kinna heavy on my very light headset, tracks good. Hat in garbage. Springie thing given to cat.
