We had a bay freeze over acouple of weeks back. I got to see a JawJacker in use. It is pretty cool. I was skeptical, thinking it was another gimmick to catch ice fisherman. But it is really nice. I am not a tip up user. But I can see using this inside my shanty while I'm jigging two other rods. I will be adding one to my bucket. Seeing it used changed my outlook on it. It is well built and easy to set up. I think it is very usefull. I usually dead stick a third line just out from where I am jigging. This thing will work perfect for that application. Only intead of hand lining like a tip up, I can reel in on a rod. Very sweet in my opinion.
