Is there somewhere (I can't find it) where the GCR lists approved devices??

The reason I ask is that, 1. I need to buy one 2. The new NecksGen device seems to have the appropriate certification AND it does not aggrevate my multibroken collar bone.

Question is it "approved" for SCCA?? It's a lot (to me anyhow) money and I don't want to make a mmistake.

Thanks
