I do a lot of stuff around water and will soon be doing a lot around snow so I'm looking to get a filter shortly. I've seen a bunch of youtube stuff suggesting the http://www.snakeriverprototyping.com/hero3/hero3plus-no-housing and I've read on the forum that some people are very happy with http://www.polarprofilters.com/product-category/hero3-accessories/
Anyone do a side-by-side comparison with them? Suggestions? It appears both of them are good with the zenmuse HD-3D
