Here are my guesses as to why u say these are useless:
BA Rescue Mats: when ya want to rescue someone, you want to do it immediately!
BA Personal Lines: Use your Hose as the Personal/Guide line!
Small Maglites on BA sets: We're trained in BA to work in complete darkness.
FireFly I/II/K DSU's: People ignore DSU's that go into Alarm so much.
Hmm...
Rescue mats: Get in, get 'em out. Trying to screw around when you are performing a time critical rescue isn't my idea of fun. Its not hard to grab someone under the arms and yank 'em out. Yeah yeah, heavier people can be hard, but there are two of you in BA atleast no?
Personal lines: Stop mucking around in the dark. Get in and search, stay in audible contact. None of this silly line-under-the-foot wide searching stupidity.
Small maglites: They are essentially a penlite. Get a good SuperSaberlite at the very least, or a nice 90 degree torch at best. That way you can work without having to man handle a torch.
Firefly DSU's: Invisible and inaudible. Other, better DSU's are widely available.
OH Controversy!
