This Psychic Friends scope detection stuff seems to be a TMO phenomenon. I've left my scope up plenty in RFB, without problems.

Generally, I will use a high scope search with the Obs scope from radar depth (more or less). This is partly for the reason aanker said, and partly because rough seas often require it anyway. I will observe ships leaving it up until they get to around 4000 yds. Then, I will start to take precautions and take it down between observations. When they are within 1000 yds. or so, I will be very cautious.

Once, I was being hunted by a couple escorts after an attack. After being deep for some time, and not hearing anything, I came up to p/s depth for a look around. It was night time. Lo and behold, there was a minesweeper very, very close by. The sneaky bugger was just sitting there, waiting for me to surface. I couldn't torpedo him, as I was facing the wrong way (and I may have been too close). I waited there creeping along pondering if I should try to turn the boat and get a shot in. It was oddly fascinating, watching the IJN crewmen walk around on the deck. I was close enough, that I could have seen them light up a cigarette, had they done so. The only thing that worried me was when their searchlight came around in my direction; then I lowered the scope quick! After awhile, they got bored and left, not being any the wiser. No psychics among that crew.
