Try it...i can hit the ice 5' in front of me and take a 2"+ chip out of the ice effortlessly with one hand. I'm fully aware of the purpose of it. Now, I am in great shape and 150lbs...I cannot hold the end of a spud bar with one hand and hit the ice 5'+ in front of me continuously without be wasted by time I get out a couple hundred yards. Two pieces or rebar can hit the ice hard! And you could move it across a hole a lot quicker, I would think that speed will count a lot at that point. I have seen people using spud bars and hitting the ice just in front of them, that would concern me.
Just my 2 cents.
Thanks,
