Ironing out the bugs I take it?

Actually no, its working as intended.

But im thinking of redisnging it after some input from kylania. .ie instead of inputting them into text boxes you draw them out, with little drag handles so you can move them around.

Also im going to add support for any number of sightings.. becase as it is right now, the accuracy depends entirely on how "correct" your 3 sightings are. Being 1 degree off can skew the results. So if instead you use 4 bearings, it will grab the course of the first 3 & last 3 and then average them out. If you add another one.. it will refine it even more etc.

I was getting pretty decent results from it (within 5 degree course), but i knew the tolerances and was carefully listening. Kylania on the other hand didn't realize this, and he didn't get the intended course.

If you are interested in using this initial test version.. i guess i can upload it as is.. but you just need to keep in mind that with only 3 bearings... theres not much fudge factor and it should only be used as an estimate.

My advice would be to open two instances of the app and take 4 bearings. Enter the first 3 in one window, and enter the last 3 in the other window, and compare the two courses.
