Ok, I've been around here awhile and I believe that I am a pretty level headed kinda guy who takes most of what's posted on GLP with a grain of salt.

There have been numerous 'Compass Setting Off' threads here and not once has my compass shown any variation.

I have it sitting in a stable position in my room, the position is marked so as to prevent the possibility of movement error. I've checked for metallic and magnetic interference and found none!

I have had this thing set up for months and this morning I find the it is off by about 1.5 degs.

Can anyone who has a similar set up check theirs please.

I live in Cairns QLD Australia.

Again, I have checked everything but can't find any interference!

Thanks Ozi
