I got the Aquadome for my GoPro and I wanted to share some pics I took yesterday.
The Aquadome is made to take split (over/underwater) pictures. I will put the link to it below, it's a little under $70.
It is easy to use, you just put the Gopro on it and screw down the little bracket. Here are some of the pics I took.
Let me know what you think! I will be taking some more pictures with this at different spots around the island.
