Video - Rangefinding Using the UZO

Video demonstrating historical plotting procedures and how to simulate these real procedures in Wolfpack (supersedes previous video):

The video is no longer available. Did you remove it?

The following is provided for historical reference. Not as a suggestion to buy it. Since it is a webshop/site for buying old maritime equipment. (IT IS NOT a suggestion to buy it)

You might want to translate the dutch text. But more importantly I find the view through the optics. Only a line is visible in the right occular! It also has a lever to switch between night and day observation. Not sure what that would do to the optics. Probably restricting the light coming through in daylight.

Should have corrected the post - I made another video the other night that supersedes this one now that we have 0.16. Will edit OP. My rangefinding is based on replicating the method the skippers used to gauge distance of hull-down ships. Since we don’t have that luxury in game (I.e. we don’t have an easy reference as to whether the mast tips grow or shrink). My method is a workaround allowing the use of real life plotting tactics. The UZO only had the line, but they simply adjusted course and speed to keep the masts the same height over the horizon and plotted based on that.

I want that UZO! I could plot firing solutions on my neighbors.

As for the night switch I seem to recall in the book Operation Drumbeat by Michael Gannon (about Hardegen and U-123) he mentions there was a feature to adjust the brightness of the bearing line. I wonder if that’s it. I really want that feature in Wolfpack along with the bearing ring around the base.

Lol. Re-reading my added emphasis not to buy it might be interpreted as if I am in the market for it. No, I'm not in. Really ;)

The night switch adjusted the brightness of the bearing line yes. You can check here: http://www.binoculars-cinecollectors.com/U.D.F._by_Anna_and_Terry_Vacani.pdf page 8 to see the mechanism.

Same paint was used on the UZO pedestal... one can read about the two rings on page 33: http://www.uboatarchive.net/U-570/U-570BritishReport.htm


I really hope we will get this implemented as now I consider these missing features as a bug.

Thanks for providing Vatikus. I do my plotting on the surface using eyeballed range through the UZO and so I would REALLY like the bearing ring topside. I agree with your statement- these crucial features need to be implemented.

Just a question:

At "Das Boot" convoy attack scene the UZO is shown with calibration scale (1:32), this game's UZO has not.

Who is wrong?

Ok, this might be sacrilege against Das Boot. I really wish I don't have to do this, but I have to considering the following:

A movie cut showing an typical (movie-style) artificial binocular view of 2 circular holes overlapping in a solid faceplate housing. Without any fading of the edges of both eye-views which you would see with real binoculars as your eyes and mind represent this.

As has been shown previously in this thread with links: Actual eyepiece views of a historical UZO binocular. With just a single vertical line without any markings what so ever.

As best as Das Boot tried to be a realistic representation, this one isn't it.
