Currently visiting Colombia and heading to the caribean part of the country. Seem to have forgotten the diving lens.. if I plug/tape up the 'sound holes', would it still be 'waterproof' to like 1 feet of water? Not that I'm asking for any warantees, just trying to figure out if the seals are equal and wether to take a risk..

Thanks in advance!
