Looking for gopro accessories

I was given a gopro 4 silver for Christmas. I'm now looking for accessories so figured it couldn't hurt to throw it out here. I also have some diving accessories (close up lens and colored filters for underwater shooting) Let me know if you have something you don't need

Thanks;

I have a bunch of things I don't use. Ill get them together, trade for the underwater stuff?

I've got a GoPro remote if you're interested.

I have a GoPro LCD backpack

I have a extra head strap and quickclip if you need them.( there still in the package unopened).
