Vivid Leak Sentinel V5
Vivid Leak Sentinel V5 is installed on the available housing bulkhead. Manual pump or electronic vacuum pump is used to remove the air inside the housing. The LED indicator would flash green and red if leak has been detected and a constant green light if there was no leak found.
The vacuum system is designed to ensure that the housing is fully sealed and prevent leaks which can damage the camera. This is a very useful accessory to give the photographer peace of mind that the camera is protected.
