I have a Brunton Truarc 3 compass. At the time I bought it I wasn't aware about declination settings or navigation basics. But recently I realized that it has offset of a few degrees (around 6 degrees). It bothers me that the red line and 0 degrees do not align properly but that is a bit of an OCD thing. What I really want to know is do I need to replace this compass or compensate for the offset. Or this is a minor error and can be ignored. I think I will mostly use it while walking 100-200kms max.

Edit: the problem is the 0 deg, red internal marking and black outside arrow marking can never align.
