Perfect for rock pools. Much easier than goggles none
The kids saw all sorts of creatures in the rock pools with this. The parents used it quite a bit too. My kids are aged 10 and 9 and this was a great thing to have in the beach bag. Goggles are cumbersome and a bit tricky to look into rock pools, this was much easier. It was also good in the shallows on the beach. We saw fish and all sorts that we wouldn't otherwise have seen.
