That is a great question. I don’t know if we have lost touch in a sense. It is just the way things and technology is going. With buildings getting built closer and closer together, the industry has to come up with new ways to combat these things.
I think some of it is that XYZ Company has one so now for me to compete I need one also. I have only seen a couple of projects that used them and they were effective, but I think that was mainly the operator. Like demobud I have seen them used on a couple of projects and thought what the heck are they doing.
