Given the extreme nature of our dive expedition, our first choice of buoyancy device was the Donut Bladder Twin Tank from Mares’ XR range, with stainless steel 15l tank bands.
These bladders are made from 1200D ballistic nylon with a 600D polyester exterior – all durable, resistant materials. The model is also lightweight and streamlined, and gave us no problems under the ice.
As well as these XR products, created for such conditions, we also took along our new She Dives Kaila SLS, Dragon SLS and Pure SLS BCDs. We thought it would be interesting to see how they faced Siberian temperatures and we were so happy to see they performed extremely well.
On the torch front, we had the latest EOS 20RZ with our trusty EOS 2C as a backup light. The torch line was great! Personally we had never had experiences with these models under such extreme conditions. We found the batteries worked fine and the torches achieved the burn times stated in our product descriptions. They always remained within the tolerance limits described, though perhaps with a slight reduction compared to what we will see on the warmer dives of our next expedition.
Check back in next week to find out how we got on with the over 700kg of luggage packed into our Cruise Backpack Dry bags!
