I use 25 pound nylon line with an 18 inch 20 pound leader. I use northern sucker minnows, hooked through the back behind their back fin. I put on one large split shot on the leader. I set the tip up in 6 to 8 feet of water, usually 6 to 7 feet. I set the minnow about half way down – 3 feet down. Pike are more in the shallows and I hear they often hang just below the ice. That is my setup. Also, I use a Frabill round tip up to cover the hole. I just caught this 28″ pike last Thursday in 6.5 feet, 3 feet down using this technique, had two other trips on the tip up, but missed the fish.
