That's a big complaint on those, I've seen. I'm always testing if it'll float with the device it's attached too: Helmet, stick, etc. I think of it more as a just in case it cracks off whatever you are wearing, type thing. If you use them enough you're bound to loose them. I've gone through 3, one of which wasn't my fault. They are priced to be disposable/broken. Sorry to hear that. I've watched mine sink in a 30 foot deep raging reef.....I knew it was gone forever.
