Ice Fishing Tightlining
Another technique to try is called tightlining. Tightlining is a technique where you do not move the line and lure once you drop it in the water, instead you watch the line for movement. When the line becomes "tight" you know you have something on it. When tightlining, remember to use a lure heavy enough to allow your line to drop straight down to your desired depth, but not heavy enough that the line will not move when a strike occurs. Many anglers use trial and error to find the correct lure.
Some folks also add a spring bobber to their line to help with strike indication. A spring bobber is a piece of metal or wire that extends off the rod tip. Any movement in the line will cause the spring bobber to move alerting the angler of a bite.
