Compass worked fine in my hand away from any metal. When I installed the compass in the console with a VEO 180 Nx computer the compass needle went crazy and pointed all different directions except North. After contacting Oceanic customer support and being transferred to someone \"more familiar\" with compass I was told that some of the batteries in the computers had somehow become magnetized which was what caused the compass to go crazy when near the computer in the console. They sent me a new battery and the compass does not become erratic when in proximity to the new battery. We'll see what happens when I replace the battery in the dive computer and install the compass in the console.
