To determine between a South l and south 2 facing house, I have to place the compass at stomach level, facing out. Do I stand behing or in front of the door and how far from the main door. Please advise. Thank You

Dear Cheah, The best is to butt the loupan up against the door. The only drawback is if there is any metal in the door or if there are any electric wires around this will affect the reading. This, of course, will affect the needle of the loupan. Take it at the door, then stand 1 meter back and check it and if necessary stand 3 meters away from the door, outside the house, and line it up to the door. You will, of course, need to read the loupan from the side nearest your stomach as your are now standing the opposite way around. Regards Di
