Perhaps. Us Robinson types are pretty johnny on the spot lowering collective when the horn sounds. But that gets practiced all the time (or should). Will there be an "instructor switch" on the wire detection kit, and how many will practice some sort of instant wire avoidance maneuver with it? And whatever gets practiced might be a crapshoot, because you won't see the wire, you'll be reacting automatically to something you assume is right in front of you and that can be avoided with some sort of fly-up maneuver.
Any warning is better than no warning, but 4 or 5 seconds would be better. As it happens, as an engineer I understand the technical challenges. Not saying it's easy!
