Quote:the diffrence between the GR2DX and GR3DX is inside live only. The GR3 DX has smoother motion on both axis.
Quote:The key to smooth operation with the Giro is balance. You'll want a long dovetail plate to slide back and forth when you change diagonal/binoviewer/EPs. You don't need slo mo controls or any tension on the Altitude knob when the OTA is balanced. Light finger tip pressure it all that's needed. I have used my up to 300X. Tracks just fine.ERik D
