I think you're asking how the seals hold up when submerged 30 feet... I don't know for sure, but I took mine down pretty far while snorkeling. One thing to be clear about - I sent my 8010 in for new seals (for maintaining the waterproof feature) and they told me there was a problem with the camera and it was too old to fix (3 years, really??) & that they wouldn't just replace the old seals and send it back. It was "pay for shipping your camera back w/out new seals or buy a new one and we'll only charge you the 'current market value' for replacing your camera with a product that is the bottom level of our cameras and KEEP your camera." (sorry that's confusing - but it was to me too!) When I bought the camera it was their top-of-the-line, so the current market value was nowhere near what I paid and their bottom level camera (that they were so graciously giving me 'such a deal' on) was actually CHEAPER on Amazon. I ended up buying the TG-1 (once again the top of the line) which cost me slightly more than it did on Amazon, but w/ and extended warranty. I wouldn't recommend the TG-1 either because it doesn't have a lens cap so the chance of scratching the lens is pretty high.
