Works underwater, can be heard over 1 mile, over 200 decibles, can be heard over crowds and rivers!
I have these for my kids and I'm so glad that I do! Especially if you are a family that likes to go fishing or camping, you know how loud it is near a river. You can't even hear the person next to you sometimes. So this is a "must have" for your Grab and Go bags!
Sold as a 2 pack for $9.99
