Can I ask what you're doing when entering the water: will you disassemble the 3 pieces to let all the air bubbles out, or just rotate the bubble release rings? will the sock already by on when you do those things, or do you add it afterwards, once bubbles are out? Looks like I let some bubbles trapped in during my first dive with the rig, at least that's how I explain the annoying black donuts on my photos, so want to make sure I get these guys out Share this post Link to post Share on other sites

The first step is to pour water into a PET bottle the night before the dive. 1) Put the sock on the EMWL: Rubber band on flat port. Rubber band on heel. Leave the EMWL vent holes open (bubble ring released). Put the sock on the EMWL. Rubber band on the objective lens. 2) Fill the sock with clean water: Fill the sock with clean water. Release all bubbles by moving the sock at places where are the EMWL connections (bubble rings are released all the time). Add more water to fill the sock up to the maximum (no air in the sock). 3) Close the cap. Now you can test that everything is OK. EMWL will focus above the surface with this "adjustment". If you have well-tightened rubber bands, it holds clean water very well. In my case, I have half an hour filled EMWL on shore. And then the water stays inside the whole three-hour freedive session. The first installation takes a little longer and I recommend trying it for the fisrt time in peace at home. If you know what and how, then the installation at the dive site will not take you more than 5 minutes. 1 Share this post Link to post Share on other sites

Thanks a lot Jan for theses detailed explanations, I hadn't suspected you carried your clean water on the site, but it makes good sense!! Share this post Link to post Share on other sites
Alex_Mustard 0 Posted August 12, 2022 I thought I'd share these images here, as they relate to the same issue. I took this photo of a scorpionfish in Norfolk, UK, this week. It was a nice yellow one. Above it is a planktonic copepod. Not that strange - except that the copepod was far too big and was in every shot in this series. And then I realised that it was trapped inside the EMWL, in the gap behind the front element - which I can just changed to for this subject. That is why it is a silhouette and also why it is so large. I am impressed how much detail you can see in the copepod. Once I realised I let it out! I have had both a fly and an ant in my dome port before - but this was a first for me. Alex Share this post Link to post Share on other sites
