Product Information
The Fantasea Hybrid Vacuum Safety System M16A is an optional pre-dive vacuum test and leak detector system that confirms the watertight seal of an underwater camera housing before a dive and monitors that seal with a moisture sensor during the dive. It is rated to 100 meters (330 feet) and runs on a 3.7V 110mAh lithium rechargeable battery with a battery life of approximately 4 days.
Who it is for
This system is built for underwater photographers and videographers who use a housing equipped with an M16 port and want an added layer of confidence that the housing seal is intact before descending, along with an audio and visual alarm if moisture is detected during the dive. It requires self installation inside the housing.

Frequently Asked Questions
How long does the battery last on the Fantasea Hybrid Vacuum Safety System M16A?
The system runs on a 3.7V 110mAh lithium rechargeable battery with a battery life of approximately 4 days. It recharges through a 5V micro-USB port in approximately 45 minutes, so it can be topped off between dives or overnight.
Can I install the Hybrid Vacuum Safety System M16A myself?
Yes, the system requires self installation inside a compatible M16-port housing. General installation guidance is provided in the product manual, though consulting an authorized Fantasea dealer before installing is recommended for guidance specific to your housing model.
Will the M16A work with a non-Fantasea housing?
It can work with other brands' housings if the M16 port's thread type matches the vacuum valve, the housing has enough internal space for all system components without interfering with operation, and there is a transparent area to observe the LED indicator.
Do Fantasea FA6500 housings need an extra part to use this system?
FA6500 housings with a serial number between 187402 and 187617 require a Fantasea M16 Coarse to Fine Thread Insert Converter installed on the housing's M16 port before the Hybrid Vacuum Safety System M16A can be accommodated. Contact an authorized Fantasea dealer to order this converter.
