Hunting for willow ptarmigan doesn’t require any specialized equipment. All you really need is a reliable snowmobile, helmet, shotgun and ammunition, appropriate cold-weather clothing and boots and, if required by local regulations, a hunter-safety orange vest.
In remote locations, you should also tow a toboggan with essential survival gear. Along with a survival kit, bring an axe, rope, snowshoes, fire starter, spare snowmobile parts and extra fuel. I also throw my GPS in my backpack to keep track of my route while stalking ptarmigan across the near endless northern landscape.
