Ahh........"The good ol days, back before you were born, I could take a twenty dollar bill and fill my car from empty to full and still have money left over for soda and a snack"

I also had no need for NV, so I went with the 512. As far as the submersion, if I'm 10 feet under water and still holding onto my rifle, something has gone terribly awry and I don't think an extra 23 feet is going to matter to me. YMMV
