Dive with the confidence that your underwater camera housing is properly sealed with this Sea & Sea Leak Sentinel V5 XB for Underwater Camera Housings. Used along with a separately sold Sea & Sea Electric Pump (SS-46126) or Manual Pump (SS-46127), the Sentinel detects leaks in the vacuum seal and warns you with an LED if it's unsafe to dive. The Sentinel mounts on the housing's accessory port.
