Regarding the Laser Radar wire detector that Lu mentioned, the only one I've heard about weighed ~600lbs and could only detect approximately horizontal wires with little clutter around them, but not all the time (I forget the percentage..it wasn't 100%).
The idea seemed sound to me, but since I'm planning on avoiding the wires, I fly where the trees are tall (so they clutter the wires), there are many wires that are not horizontal (ie large spans or skyline logging cables), and I have other ways of using that 600 lbs, I didn't think the wire detector would be that useful.
Also, there was a question whether the detector would pick up a wire threat with enough time for you to do something about it.
Does this one developed in the UK have similiar limitations?
