Hugyfot developed a pre-dive vacuum check system called ‘HugyCheck’ which enables the photographer to perform a vacuum test prior to entering the water. This test will indicate whether the housing has been closed properly, and whether the housings’ O-rings are in good condition.
The HugyCheck system consists of:
– electrical vacuum pump
– one way valve (on one of the bulkheads*)
– LED pressure indicator (on the camera hotshoe)
– leakage alarm
