Used to ice fish the mouth of the Ganny in Port Hope using float gear.
Would even use the long rods. Pretty funny standing 10 to 15 feet away from the hole fighting a steelie.
I spent many a day pinning in January and February and the only time I ever had issues with my pin was if it got dunked (by me slipping in the river or dropping my outfit) they don't spin so good once that water freezes.
If you don't submerge them they work fine in the cold.
