I downloaded Wazoo's bearing tool (the upside down protractor). However, I only found it useful for checking the heading of a contact on the map. I was sort of hoping it would allow me

to draw a line precisely to 63 degrees off my bow, for example. However, it does not help if the boat itself is on a heading of 57 degrees. Is there a way to rotate the protractor so the

000 points at the bow of the boat? While I'm waiting for the answer, I made up my own protractor (too lazy to go to the store). It's a clear acetate sheet from an overhead

projector, on which I drew a circle and lines going from the center to the edges. Each line represents 15 degrees. You then place the sheet on the screen, align and plot away. It is still

not perfect, but a lot better than nothing. So is there a tool like that already and I wasted 2 hours of my life making it?

Were you in the cub scouts Foehammer? you show great initiative. I wouldn't say you've wasted 2 hours of your life no, but I might arm ache holding that up to the screen so often http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

hmmm great idea, what could more realistic than getting your bearings with a real protractor held up to the screen, i like it. i also like my idea of installing red lights inb my computer room for night time.

No, I wasn't in scouts. I jsut got sick and tired of plotting a course using only hydrophone and sonar, only to find out that my lines that i draw miss by about 5 degrees, which results in a less than accurate course plot... But I AM in army cadets as of now http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Hey, McGyver. What can you make with sticky-tape and string? http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif
Nope, seriously bud, good thinking. Send us some pics or a diagram, could be handy for others here, call it the

Sure, I'll try to scan it, and see what happens. Now, the problem is with printing it on that acetate sheet. I had a friendly teacher do it for me, just like she makes her own overheads. Does anyone know how could I do it if i come up with version 1.2? http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Brw, I never watched McGyver, heard of it tho http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Ok, the scan didn't work at first, but I managed to make it work http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif Here is the picture. I know, it is not precisely accurate, but works just fine in SH3. You need to somehow print it on the acetate sheet. The ink from my printer rubs off. Does anyone know how teachers make their overheads so that the image stays permanently on that sheet?

yeah im pretty sure they use laser printer just a guess. yeah i didnt take cadets or anything but how do you use that

There are clear films for sale that are specially for projectors, personally i use an encapsulator, they are not that expensive (you put the clear sheet in between encapsulating film and then it is sealed together using heat)that way its not so flimsy and its damage proof. Well done, i can see what you are trying to do now... http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

As jlpilkey said, you would be better off using a laser printer, which 'fuses' black toner powder to the surface of the paper/acetate, unlike an inkjet which sprays tiny drops of liquid ink (which is why it eventually rubs off, even after it dries).

If you use a laser printer, make absolutely sure you use transparency film which is designed for use in laser printers!! If you use regular acetate, it will melt inside the printer and may even set it on fire!! http://forums.ubi.com/groupee_common/emoticons/icon_eek.gif

e.g. something like these (http://www.staples.co.uk/ENG/Catalog/cat_sku.asp?CatIds=,&webid=353342&affixedcode=WW)

Yeah, that's exactly why I was afraid to try that. In regards to

anything but how do you use that
You zoom in on your boat, as close as you want, in the Map screen. Now, that place where the lines meet, put that right on top of the boat. Now, spin the thing so the line with 000 is

directly ahead of the boat. Listen to the hydrophone operator. Suppose he says "merchant now at 065". Use the line drawing tool, and draw a line a little bit to the right of the

060 mark on my diagram. Now send some pings with a sonar to find range, and draw the line exactly of that length. Wait a minute, repeat. Repeat after 1 more minute. Now you have

target's course. You can now guesstimate the speed, or use the chart of propeller rotation times, or maybe the BdU told you what its speed was in the original contact message. Notice,

you do not have to raise your periscope even for a bit, very handy in the late years of the war. OH! this is useless if you have auto map updates turned ON. Only useful in 100% realism,

since it doesn't automatically draw the lines for you. I hope that helps you, fellow caleuns.

P.S. If you complain about still not beig able to draw exactly perfect lines, I will tell you that estimating where 245 degrees is between the lines that represent 240 and 255 is MUCH

easier than without any point of reference. Just use your imagination and breakdown the space between the lines in 3 equal parts, and now you have an even more precise way of finding bearings.

thx this will help now i wont be flying around the atlantic searching for ships hopefully

Haha, it is meant to assist manual targetting on 100% realism, as well as without using a periscope. It won't actually help you find ships in the Atlantic http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif So if you are just strating out and use automatic map updates, this wheel thingy is totally useless http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

oh its just for targetting. oh the only thing i checked of for my realism is dud topedoes i thought it would helf for meeting for contactsat almost exact location and my realism is something like 96%
