What method are you using? Guestimating with the range rings how many thousand meters away they are and then fine tuning with the readout, or using the A-Scope to get the thousands? Inetersting, as I only thought it would be useful below 10 km.

Blimey, that's extreme shooting - are you using one of the playable BB mods?

Very observant! This is an issue I have been struggling with and I don't think there is a way round it. It makes no practical sense, but may be fine operationally. The hydrophone also has an arc of detection, but the hydrophone has the arc either side of the contact, with the correct bearing being the middle of the two bearings where the contact is lost. The radar has an arc that abruptly ends right on the leading edge. It's as if the radar beam is lobed out to the side, but that doesn't make any sense, as if that were the case, you wouldn't pick up the contact before the sweep got to it and lose it right on it. I can only ssume this is a bit of stock game weirdness.

Out of interest, how are you measuring bearing? The stock camera doesn't allow you to look at the radar antenna bearing indicator properly and it's also not accurate in itself - the bearings are only marked in 5 degree increments and even these aren't accurate - sometimes off by 2 degrees. I am working on a high res accurate bearing indicator, but with this I have noticed that targets directly infront and directly behind are accurate, but ones to the sides are off consistently by half a degree.

The bearing indicator problem may be a game measuring error, as the antenna apparently goes between 0 and 360 degrees, which is 361 degrees in a cirlce, or due to the measurement errors, it's possible it's a 3d model placement problem in the interior, the indicator being position a touch too high/low, and therefore being accurate at 0 and 180, but innacurate at the sides.

That's a bonehead mistake by me. I tested it all before packing it up, but must have packed one of the wrong files in. Thanks for spotting and I PMed you a new link to the (hopefully) corrected file.

Would anyone else like to test this?
