I don't understand the question, possibly because I don't know the Gravity products.
I have "modded" my Basilisk. I installed 4 neodymium magnets in the empty puck (the puck under the mouse can be replaced with Wirelesschargin). With 4 more magnets under my mouse pad, I can now "snap" the mouse into place like a magnet.
So I would say mangnetism does not interfere with the electronics of this Basilisk V3.
