The farther one a bit more than 4 km, usually i prefer to shoot at nearer distances (less than 1500 m), but due to bad luck with the weather i´m used to shoot without seeing the target, just with the data from the hydrophones, nav map and manual input in the TDC.
i´ve reached the point that the sight of a ship through the persicope get me so nervous that makes me miss the shot:rotfl: :rotfl:
