No need to have Mida if your helmet lets you use any weapon and will keep the active radar.
Running around with Knucklehead Radar and Adjudicator (or Antiope-D/Atalanta-D) will piss off your enemies easily. I wouldn't suggest attempting it until Bungie nerfs Prometheus Lens though, unless you want to just use that (since the hemlet will keep active radar on ANY weapon: kinetic, elemental, or power).
