ICSD New Shipwreck Challenge...

I know that feeling. My first ice dive, post training, was in a WI lake that killed one untrained ice diver the previous winter (facts may be off a bit). The story was that 2 divers cut a hole and entered on a line together with one holding the line and the other buddied up. The line holder had a reg failure and bolted to the hole taking the line and not his buddy. So my dive, I couldn't clear my head of the sensation of being all alone under the ice, waiting for the end.
