No. It's the same case as all of the other GPC cases though. They are all waterproof.
Ever ridden a motorcycle? If so, you would understand that "waterproof" is not always waterproof, and when it comes to most things, they are water resistant. Ride in a torrential downpour for a few hours and even Gor-Tex will break down and allow moisture through. I was hoping to know if it has been tested outside of a factory setting. I tested one of my last pelican cases, and found there was a flaw that allowed water to get into the case. It was replaced, but I always test them now, no matter what the manufacture says.
I dont have either case, so I have no reference. This is why I asked the question.
