Be aware there are legal implications in Alberta when cutting a hole big enough for someone to fall in to. Also, be sure to mark the hole well when you are done. Finally, the saw is in the neighborhood of $200. Cheers.
The ice saw is only good down to a foot or so apparently. I've cut a few holes in ice 3' thick on fly-in lakes in northern Saskatchewan with a chainsaw and a spud bar. You find out who your friends are when it comes time to decide who is climbing down into the hole to finish it.
