Requesting Periscope bearing mod.

Hello.

I'll get straight to the point. Does anybody here have a precise periscope mod for Silent hunter 3? so that one can see the exact bearing of the target? right now, the bearing intervals in the scope and the UZO is 5 degrees or so. i would like to see every degree in the periscope.

I have looked everywhere on the net, but I came out empty handed, and i was hoping that you guys could help me.

Thanks.
