C.A.M.P. Radion - Ice Screw
One of the positive features of this design though was the fact that it can be clipped to the rope before it is wound in (or out), meaning that the screw won't be dropped. In use we found clipping screws to the rope before placing them to be impractical, but taking them out whilst they are still clipped to the rope (whilst you are seconding) did actually work a treat. So no dropped screws by your second anymore!
Summary: Decent screws with an interesting double unit on the head. Quite heavy for the size, but could be used just with a carabiner instead of a quickdraw, although we preferred not to. Awkward to clip. Interesting reverse thread design could increase holding power in brittle ice.
