Housing Sentry Overview |
Housing flood – the underwater photographer’s worst nightmare. The swim back to the surface is agonizing. You want to go quickly but, for safety reasons, you cannot. You know the amount of water entering your housing will likely increase as you get closer to the surface – less pressure, more leaking – but you must get out. The expensive equipment in your hands is being ruined before your eyes…
Do you want to avoid this nightmare? You need the Housing Sentry from UnderWater Camera Stuff.
The Housing Sentry allows you to pull a vacuum on your housing, creating a stronger seal for the o-rings and holding the housing parts, such as lens ports, more firmly in place. With ten inHg of vacuum, a pull force of 58 pounds or 26.3 kilograms was required to break the seal of the lens port on the test housing with all of the port clips disengaged. This test is a measurable indication of how the Housing Sentry aids in securing your housing assembly.
All versions of the Housing Sentry are designed to check the status of your housing before you enter the water. The Housing Sentry-Complete will continually monitor the housing throughout your dive and will regularly notify you that everything is secure or quickly alert you if a problem is detected.The Housing Sentry can be installed in virtually all housings regardless of the manufacturer or model. There are currently six customized vacuum connectors available depending on the type of installation desired including (1) an unused, half-inch, unthreaded bulkhead such as Aquatica or Sea&Sea; (2) an unused 14mm threaded bulkhead such as Nauticam, Subal or Seacam; (3) an unused control location in an ikelite housing; (4) a bulkhead with an unused Nikonos connector; (5) aluminum housing without an open bulkhead and (6) acrylic housing. Options 5 and 6 require an additional opening be added to the housing.
With the Housing Sentry, you now have an additional tool to help guard against the nightmare of a flood.
