We have not got those yet , if that is the case I can't wait for it to happenAsk your sup/manager... I use the clip because I can't latch seat belt with the black pouch. I keep 3-4 in my lunch box because I'm Always getting them caught on bulkhead door and they snap. The diad 5 has a special adapter that clips to bottom that allows you to use diad 4 belt clip for those that don't know.
I might be old school but I have never. And I mean ever used any type of clip or pouch.
