A compass needle does not need to move for you to veer off.
Other than current, how does this happen?

Come on, it's a compass, it isn't GPS.

Well sure if the user is holding it off level the needle won't move at all even if the user is swimming in a circle.

Just so happens my right leg is a lot stronger and bigger than my left and my left leg is shorter than my right. I must compensate without knowing it.
Have you ever tried to swim a straight line with no visual reference? I'm definitely going to be swimming in a circle. That means, if I am not paying pretty close attention when following the needle (different from picking visible way points), I can introduce a bias. Nothing really wrong with some error, left and right, as long as they mostly balance. Practice can really pay off in this area.
You mean like I do when night diving? The compass is my reference, like my depth is my reference at night when I ascend. I've had lots of compass practice, decades on land and underwater. Being off 15 20 deg on a 100 yd swim isn't too bad, ya end up pretty close to where ya want. I'm no Navy SEAL after all.
