Guys, You are discussing 'Needle Tip' here and nothing to do with the direction the compass points Tip is due to the compass needle following the Earths Flux lines as they 'drop' back to the Poles.
'Needle Tip' only occurs as you approch the Magnetic North and South poles within the Arctic/Antarctic zones - and with a less well made compass you can get needle lock, where a compass placed on a flat surface has its needle touching the bottom of the casing, and so produces an innacurate reading - as it is unable to turn - quite easy to miss in arctic conditions.
That is why compasses marked 'Global' are used for these environments they are tuned to resist tip and sometimes have a deeper casing - these Compass are not neccesarily required for the RTW use, However not all Compass' are the same.
