don't know if anyone else has run into this or not but I'm hiking thru a lot of brush to get to my places here in Wa, and I noticed that I'm takin a pretty good chance of tearing or poking a hole in the very thin plastic on face of F5, so I bought a piece of 1 eighth " lucite and cut to shape and afix with dab of rtv. works nicely, and should the need arise can slip a feeler gauge under it to remove. I feel much better about getting under and around brush now!
