[REQ] radar warning/hydrophone contact lines

[dize]

hi there!
im not sure if something like that is alreday avail or not. thing is, im playing with mapupdates on, since i kinda dont like all the plotting things. the problem with this is though, that when u have these lines enabled, showing the direction or the hydrophone/radar warning contacts, it is imho way to precise . they are showing the exact distance to the taget, which is especialy dodgy for the radar warning reciever contacts. it is easily possible to shaddow a convoy from large distances, with only the radar warning lines.
according to what i have read about this topic, these devices where rather crude in many ways. especialy the early sets, had only a simple "strength of singnal" function.
i realy would like to use a set of lines, which only gives the direction of the contact for the radar warning device, and possibly the same for hydophone contacts. im not sure how precise the sound gear was, when it comes to meassureing distance.
