My dad just recently got out of ice fishing and sold me his Zack Shack. He had an Ion auger that he bought and never used and threw it in on the deal. I love it. It is light and easy to use; my wife has no problem drilling a hole with it. My only complaint is that it "dances" around a bit until it starts to dig. Also, make sure you have an extension. Once the ice gets a bit thicker and your drilling inside the house you run out of flighting real quick.
I just cant imagine fishing a 6 inch hole. I prefer 10 inch haha so the crappies can get off in the hole easier haha.
Multiple 10 pounders in our group have come through the ice on an 8 inch hole with barbless hooks and no problems. Apparently not many have used this Fuel drill/clam plate setup. It was all new as of last year. It is nothing like I have ever seen. After using a friends setup most of last year for ND perch/walleye I will never bring another auger for that purpose.
