Mag readings are showing various responses under no change

Just received my puck and was tinkering around with it and noticed that calls to Puck.mag() show varying responses over time with no movement of the puck. Currently I've updated to 2v14 and the responses I've seen polling at ~1 second apart look similar to:

{x: -32768, y: -32768, z: -32768}
{x: -121, y: 749, z: -219}
{x: -32768, y: -32768, z: -32768}
{x: -32768, y: -32768, z: -32768}
{x: -112, y: 752, z: -201}
{x: -32768, y: -32768, z: -32768}

I've tried checking the forum for anything similar but not seen anything returning such wild jumps. I thought at first maybe I was making calls to fast as I wasnt calling Puck.magOn() but Im not positive.

Is there something I might be missing ( or maybe im just in a big magnetic field??)
Thanks!
