An ice auger is a tool used to drill holes in ice, primarily for ice fishing. It typically consists of a sharp, spiral blade attached to a long handle, allowing users to penetrate thick ice layers on frozen lakes and rivers. Ice augers can be manual or powered, with powered versions often being more efficient for larger holes. Using an ice auger is essential for anglers who want to access fish beneath the ice. The size of the hole can vary, with common diameters ranging from 6 to 10 inches, depending on the type of fish being targeted and the fishing technique employed.
