liquidoceans

I bought a fantastic Rolleimarin last year with the firm intention to use it.

  I have tried it snorkelling last summer max 2/3m it seemed watertight  but left a tiny bit of water in after 15/20mn in the water. It almost  could have been mistaken for condensation if not for the salty taste of  it. As a consequence I decided not to try it any deeper. I changed the  main ruber seal but that did not change anything.

  I have been told that I should see some “cup seals” inside the  housing but can’t find anything of the sort. There is absolutely no  information on the net about it. I know it is abit of an “exotic”  subject but any help would be great !
