In winter 2011, a friend of mine was ice fishing on Oro 7 - Lake Simcoe. Around 10 am, he separated from the group of people he was fishing with previously. He was away at least 400 meters from a pressure crack, walking on the ice covered by fresh snow. The conditions seemed perfect. In one moment he went through and he was up to his neck in the water. The depth in the area he was walking was almost 100 feet. He yelled for help, while was trying to get out.
Three men on Ski-Doos stopped immediately. One of them jumped from his snowmobile, made a few steps and also went through. He was still far away from my friend. The whole area was dangerous.
Luckily, both managed to get out. My friend was wearing a survival suit and said after that if he did not have the survival suit on him, he wouldn't survive.
Also he said that he managed to get out because he remenbered how to get out from YouTube videos.
