Is the range displayed in the attack periscope in feet or yards? I always thought it was in yards.
I've been chasing convoys and attempting attacks at 1000 yards, which aren't going so well.
Are you attacking at 500 yards, or 166 yards (500 feet), or is the periscope in feet and I've been reading it wrong all this time?
I need to try this method, as I am not having much luck with convoys (made a topic about it without noticing this one

)
