I took my first flip this past weekend and my elite 4 went for a dip less than a minute but the thing filled to the brim with water. I got it sitting in rice but I'm pretty sure it's done for. My question is aren't they supposed to be waterproof? I've had the thing less than 3 months. I didn't notice but I'm pretty sure a wave from entry knocked the protective sd card rubber deal off before I flipped. The ads say perfect for kayaks. Do they not expect you to ever flip??
