That is a terrible accident. My sympathies to the families. I ice fish almost every day during our Vermont ice season. My home property is on the lake and it is still frozen out front of the house. Every time I am on the ice I wear a flotation ice fishing suit along with a set of picks. I used to wear an Arctic Armour flotation ice suit but upgraded this year to a newer technology made by Striker. The new Striker Climate suit has zip in liners in both the coat and bibs so it is much warmer, cuts the wind and is water repellent. When the AA suit first came out I was one of the first to buy one and since that time have encouraged all my fishing buds to wear a flotation suit. Most of the serious fishermen now are wearing some form of a safety suit and almost all carry picks to help pull them back onto the ice if they did break through.
