Using Stadimeter unlocked ?

[gumbeau]

I think I should be able to use the stadimeter without the periscope locked on a target. Basically I want to be able to input all of the TDC data without exposing the periscope for an ambush shot similar to the Richard O'Kane attack method described elswhere but with range info input to the TDC from a plot.

I've searched and can't find a thread on it.

Thanks in Advance
