Yet another 'periscope' thread...

While the impact on detection may be debatable, the hard facts that I've found so far is that they are the same aside from the OBS scope can look straight up.

They seem to have the same FOV, turn at the same rate (I have to move my mouse the same distance to do a full 360 degree rotation) I don't see any difference in "image contrast or quality" at night.

I patrol with high-scope even though it has no effect, because they did it.

Happy Hunting!

"I do not think it is unrelated. I actually see better at night with the observation scope than I can with the attack scope"

Original topic is about being seen, not seeing. Most used the night scope (observation) after first contact at long range, even in the daytime because it had better magnification. At closer range they went a few feet deeper and used the attack scope because a 3 inch diameter pole is harder to see than a 6 inch diameter pole. What the OP was theorizing was all the magical psychic detection might be from users raising the observation scope instead of the attack scope at close range, but people are reporting detection from 4000 yards away - at that range a telephone pole wouldn't be visible, ergo which scope is irrelevant.

Close, what I was positing was using the attack scope got you spotted because it stands 5-10 feet taller.

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.
