ACM mode, use the change scale binding to flip through the modes. Isn’t 37KM as ACM used to be hard capped for all radars at 19km or unlimited when only measuring velocity (PDV).
CAS20 isn’t just ACM @ 37KM its also the scan pattern, what we have is the scan pattern not the range figure.
I mean for me it’s doesn’t really matter since ir hmd has up to 30km anyways (it says 10km on the interface but since it’s ir it can lock all the way up to 30km). I like locking in ir then switching to pd for surprise factor
