That will do it LOL I remove the cover every time I detect I have even used it with out the cover just to see if it detects targets any easier which it did not the Pulse dive is a vary good pin pointer, I also have the fisher F Pulse, I like the pulse dive better as I can not even hear the F Pulse even at full volume or full sensitivityYou want to hear something funny. Ijust tried to take mine off. No luck, ran hot water over it, tried my suggestion with the adjustable wrench and it did not work. What I did to get it off was to lightly tap the top edge of the cover where it snaps onto the pinpointer. There was a small bit of very fine dust/dirt inside the cover.
