The FRX100 VA M16 Housing was specially designed for the Sony Cyber-shot RX100 III, RX100 IV, RX100 V and RX100 VA digital cameras.
The FRX100 VA M16 Housing features an M16 port specially designed for the Fantasea Hybrid Vacuum Safety System (not included with the housing), which contains both a pre-dive vacuum check and an on-dive leak detector. 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.
