Blackmagic Ursa Mini Pro

Thanks huggie11

So happy that your setup is satisfying your needs, but we too require a deep water housing and are so surprised that, across 5 different forums, there appear to be only 2 other users in the entire world that want to take the URSA underwater.

So dissapointing.

I have a Shraeger (bicycle) valve installed in the top of the housing and I slightly pressurise it with a bicycle pump to make sure it is sealed before jumping in the water.

 

Just be aware that at a certain depth depending on how much pressure you add to the housing the pressures will equalise leaving very little sealing force on the o-rings.  O rings seal tighter as the pressure difference over them increases and need pressure to seal properly.  You are probably helped by the fact you can add closing force with all those wing nuts.  This why leak detection systems pull a vacuum on the housing as it pre-loads the o-rings usually the vacuum is equivalent to a depth of about 2m.

Dont worry Feroxed, let them sleep. Its to our advantage when this camera is housed that no else is interested.

 It is an interesting camera for sure and to have it housed would be interesting. Its just not looking likely. Unfortunately.
