Vivid Leak Sentinel. Underwater Housing Vacuum System. 

Vivid Leak Sentinel Underwater Housing Vacuum System: For only a fraction of the price of other similar systems, you too can now have Leak Sentinel, a pre-dive vacuum leak detector that will eliminate guesswork about the housing integrity. Concentrate on your photography, instead of worrying if today is your turn to experience the underwater photographer’s worst nightmare.

The new improved version of the Vivid Leak Sentinel underwater housing vacuum system features a new calibrated pressure sensor and processor.

The complete electronic circuit and the battery are located in the robust, anodized aluminum valve body. Providing even more convenient operation and ease of installation.

Green/red LED lights are visible through the transparent acrylic window. No complicated installation around the viewfinder in non-transparent housings is required. LEDs are always visible, not only when you look through the viewfinder.

The included hand pump for the underwater vacuum system is lightweight and requires no batteries. No nasty surprises when you are far from the coast. It achieves required underpressure in average housing almost effortlessly.

The installation is simple and straightforward. In most cases done by either replacing the bulkhead or just screwing the adapter into the accessory port. You can check the tightness immediately after installation, making the process risk-free.

Custom adaptors for various housings/bulkheads are available. The circuit is self-calibrating, and as such suitable for altitude diving.

The underwater housing vacuum system can be mounted to any underwater housing with an M14 or M16 bulkhead.

Temperature compensation prevents false alarms, and overnight function makes it possible to set the housing beforehand. Switch the circuit off and keep on monitoring later without repeating the process, thus saving the battery and time before the dive.
