8. Operation of HugyCheck system
The HugyCheck system is a pre-dive check system that allows the underwater
photographer to check prior to the dive whether the housing has been closed
properly and whether the o-rings are in good condition. An electrical vacuum
pump will create a slight under pressure inside the housing which can be
monitored by means of an LED pressure indicator on the camera hot shoe.
Components:
-
circuit board
-
hot shoe with LED pressure indicator
-
electrical vacuum pump - one way valve
-
moisture sensor
