Abstract

There is disclosed a smoke generator for use on underwater exploration devices. Upon descent of the exploration device, the smoke generator is automatically armed when hydrostatic pressure increases to a predetermined level. Upon ascent, the smoke generator is automatically triggered when hydrostatic pressure decreases to a predetermined level.
