The Leak Sentinel V5 allows you to check the housing's vacuum seal before diving. Although small in size, the Sentinel V5 is equipped with a pressure sensor and built-in LED along with an external vacuum pump. The pump creates a vacuum inside the housing, the sensor detects any leaks and the lights let you know if it is safe to dive or not.
