After a quick look through their web site, I do not see any specific application for GRE. Looks like experimentation and trial & error would be the only route.
They do have some cool stuff. A little expensive though. Go to Radio Shack and get a vent mount cell phone holder. They work great! I paid under $10.00 a piece for the ones I have. The PSR-500 will fit in them.
I Will Have A Look At The Vent Mount Before I Do Anything ,but I Really Like The Way Proclip Seems Tp Work And The Ability To Get A Adapter Plate That Tilts 10 Or 15 Degrees Seems Perfect For Me . I Am A Machinist So I Btlieve That I Can Make A Plate That Might Adapt To The Proclip. However Thanks For Your Interest And Advice. Sincerely Paul1
