Steve, and everyone else. This is a bit off topic, but as a scuba diver, pressure and duration aren't just pretty critical, they are the primary go / no-go for any equipment purchase. And at the same time, this is exactly the information that is consistently hard to find for any piece of equipment not specifically branded as suitable for diving. I'm not at all surprised that it does not appear in a Pentax white paper .... I'm not interested in getting embroiled in whether it is "just marketing" versus "white paper".
Equipment that is branded for scuba diving routinely indicates maximum underwater depth (or maximum pressure), and sometimes maximum duration at that depth. At the same time, the consumer will generally pay a price premium for that word "scuba". I have a number of pieces of equipment that I use scuba diving that were marketed for different audiences. Some I had to use my best guess and take a chance that it would survive my test dive, and some, while I think it would work, I pass on simply because the risk of failure is too great.
Getting to the bottom line... if a manufacturer doesn't give, nor will provide, pressure and duration specifics, you have two choices. If your wallet can tolerate failure, make your best guess and test it. If your wallet can't handle the risk, assume that something like "weather resistant" means at best some light drizzle and you will dry the gear as soon as possible.
