Hi Silv, do you realise that magnetic south and polar south are not the same ?
polar south ( the south you need ) is 14 degrees from magnetic ( using a compas ) , I cant remember weather its east or west , but if you google it you will find which way .
Also its great to see you out there giving it a go , its a major learning curve , but stick with it , it does get easier . I know I have been here .
.
Hope this helps , if not I am sure someone here will sort you .
Brian.
