Probably the ice diving is the craziest kind of diving. First of all, everybody hates cold water and it's definitely cold when it's frozen. And not only the water is cold but the air as well. Another problem is the planning of the dive: because it's not an open water dive, quite dangerous, so you need safety line and surface support.
In Hungary there are ice dives in every winter. Some organizers use to invited me and two years ago I decided to try this. I felt this is a challenge I need to face. I packed my thick neoprene drysuit, some undersuit, two cold water regulators and the ordinary stuff like mask and fins. Dressing was comfortable in a heated room but the too much undersuit made my moves funny. After I took on my BCD with the tank I wasn't able to walk normally. The ice was slippery, I needed a hand.
While I was sitting with my legs in the lake I thought I was insane. "Why do I this?" But I didn't have the chance to give up, they tightened the rope and I descended with my buddy. Under the ice the visibility of the usually murky lakes get better. We saw a bit more of the underwater scene, later we touched the bottom of the ice but after 25 minutes even in drysuit I felt the cold. My face where it wasn't covered by the mask seemed frozen. But anyway, we survived. Somebody pulled me out of the water and somehow I walked to the heated place again. I did it. I had my first ever ice diving experience!
And when I took off my diving suit I said to myself: "...and the last one!" But two years gone since so I think a diver should "never say never again".
