How To Get Range In Periscope View ?

[gapman]

I am just getting started with SH 4 and loving it, but I can't find the "range to the target" in the periscope view. In Sh3 it was plainly shown, but I can't find it anywhere in the SH4 periscope view. I am playing on the easiest/novice settings to get my feet wet. Anyone know where this data is ? Thanks

It's on the slideout TDC on the left side of the screen (Click on the protruding tab to pull it out). AOB and Bearing are shown in the top and bottom dials, while Range and Speed are shown digitally in the middle between the two dials.
