I use my SpyderCube for determining whitepoint and exposure data for my scuba diving photos. Can I use SpyderLensCal similarly, for setting autofocus for underwater shooting?

SpyderLensCal was not designed for underwater use; but as long as you are willing to accept any shortening of its lifespan caused by exposure to water, or saltwater, is should allow you to correct you autofocus for the different conditions which shooting underwater produces.
