Spool the line with some good tip up line. I would fill the spool up as best you can, as Pike will run like the devil on a tip up. The last thing you want to do is run out of line on your spool.
I use Quick Strike rigs on my tip ups. They hold the bait well and I get good hook sets. With them, there’s no need for a leader, they are built out of leader material.
I set my tip ups, so the bait is just below the bottom edge of the ice. On bigger, deeper waters setting the tip up depth can be tricky. When you get a “flag” pick up the tip up by it’s frame and don’t touch the spinning sprocket that holds the flag. Carefully grab the line, or spool out some extra line and wait for the fish to take up the slack and give a pull. I almost always wait to feel the fish.
Some people handle tip ups differently, but this is what works for me. Also, I rarely run to the tip up. I feel it can spook the fish and lead to missed opportunities. I see lots of guys sprinting to flags, that’s not for me.
There’s lots of guys here that can help you out. Good luck tip up fishing this year.
