if someones new to RDAs you should be telling them to spend the 2 hours needed to make a tracker. At GM you get a 60 tile track radius which can allow you to cover 3x the ground, if you get the crystal w/upgrade you get 80 tiles and cover 4x the ground. telling people tracking doesn't matter is just bad information (but i guess we don't want them finding them?)
its 30 / 40 radius
