I'm working in the high Arctic for the next few weeks and decided to take my P3A with me to video some of this amazing landscape. Tonight I had an opportunity to shoot a massive iceberg floating past a couple hundred meters offshore. I calibrated the compass and had to do it a second time as it indicated it failed. I had a good to fly light with 15 satellites and took off. I got half way to the berg when the calibrate compass light came on and it was flying eratic. I had a hard time bringing it in with a mere 20km/hr wind. Not sure if I'm to far north for the compass to work properly or there's to much mineral in the surrounding rock. I haven't upgraded firmware yet as all worked great Any thoughts.
