Not sure about visual other than guessing but if youre running TMO 2.5, the radar range unit will get you a distance.Don't mind cheating a little, can measure the distance on your nav map from your sub to the map contact and then insert it into TDC. Pretty much like using the periscope, obtain speed, range/bearing, AOB, input into TDC, take a final bearing and fire, adjust spread accordingly.Major difference is TBT is easier to spot targets with at long ranges.
