Now this is something else. Ever since I saw photos taken with a GoPro dome accessory. I knew I needed it in my life. I ordered mine off Ebay, it comes with the waterproof housing built on. I intended to have it for Puerto Vallarta, but it didn't arrive in time. If you're planning to a vacation and need this ASAP. This took a month to arrive. So order yours early, as it is coming from China and will take forever!
Note: The dome adds distances between the camera lens and the water. By offsetting the water against the dome, you achieve this nice split between whats under water and above.
As I can't wait to use the dome in Hawaii this May. For now enjoy the photos taken at the pool on the roof of the Standard Hotel.
