Snorkeling with GoPro 10 - do I need a housing? Filters?

[JDelage]

We're going to Hawai'i this winter and I just got a Hero 10. We'll do a bit of snorkeling including one night with manta rays. Questions to you all:
- Do I need a housing for snorkeling? I expect to go no lower than 30 ft / 10m (max!)
- Do I need a filter, or set of filters?

If yes to any of the above, do people have strong recommendations for a housing or filters? My default would be to just get the GoPro accessories...

Thanks!

Hero10 is rated for 30' by itself. Don't go beyond 30' and no housing needed.
As for filters, I'm going to say no. You won't be deep enough to need them.

While the 10 is rated for 10m by itself, I flooded one in less than that. So I would use the GoPro housing just in case. And if you use a housing you will need antifog inserts.

Beyond that you won't need filters with the 10 in snorkeling depths.
