I started with the Polar Pick listed a few years ago but I found the rope breaks off the small rubber loop when pulled to hard when I have had them around my neck and through the arms of my jacket. Also they can sink. I have since switched to these (link below) they float and seem to work better with the string not breaking off.

I wear them anytime I'm on the ice either fishing, snow shoeing or out on the sleds.
Enjoy the snow everyone finally some has arrived!
