Yes it sometimes does but it is usually due to changes I've made in the cockpit. Also it is important to calibrate your compass to how you usually sail. For me I always have my plotter, depth and AP on. I actually have two deviations cards, an electronics on card and an electronics off card..
Interesting ... How different are they? Could you scan and post them?
