Description

LEAK SENTINEL V5 XB – pre dive vacuum leak detector for any UW housing!

With temperature compensation, low battery, overnight and reset function.

For only a fraction of the price of other similar systems, you too can now have Leak Sentinel, pre dive vacuum leak detector that will eliminate guesswork about the housing tightness and let you concentrate on the photography, instead of worrying if today is maybe your turn to experience the underwater photographer’s worst nightmare.

The Leak Sentinel features a calibrated pressure sensor and processor. The electronic circuit is located in the robust anodized aluminum valve body for convenient operation and ease of installation and the battery is installed in the camera housing.

The green/red LEDs are visible through the transparent acrylic window, so 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 installation is simple and straightforward, and is 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.

The circuit is self-calibrating, and as such suitable for altitude diving.

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

The principle of operation

The housing is closed 15-30 minutes before the dive, with the camera installed and the circuit switched on. Red LED starts blinking, indicating ambient pressure. The hand pump is fitted to the threaded valve body and the air is pumped out of the housing. After approx. 20-25 strokes, the green LED issues one long blink, then keeps blinking green steadily, indicating the sufficient vacuum. The additional stroke or two ensures that the circuit is not on the edge of threshold. The pump is then removed and the protective cap replaced to ensure air and water tightness. The LED is then observed for 15-30 minutes. Green LED blinking indicates that there is no air leakage (safe to dive). After the dive, the protective cap is removed and the pressure is equalized with the simple sideways movement of the rubber valve.
