The Hybrid Vacuum Safety System M16C from Fantasea Line is an optional pre-dive vacuum test and leak detector safety system for underwater camera housings. The system allows confirming the watertight seal of the housing prior to the dive, using the vacuum system, and monitoring the housing seal during the dive using the moisture detector.
The Hybrid Vacuum Safety System M16C requires self-installation. It can be installed and used with Fantasea housings equipped with an M16 port or with other brands' housings with M16 ports, provided the thread is compatible, there's enough interior space, and the housing has a transparent area through which the LED indicator of the vacuum safety system can be observed and monitored.
