Ice fishing is a challenging sport that requires you to fish on a frozen lake. Much as fishing in general calls for basic fishing items such as the fishing lines, bait bucket and fishing rod. With ice fishing, you may need to add a few more essentials such as an ice auger for drilling a hole in the iced water, a skimmer to scoop out the chips from the drilled hole and a sled to haul equipment to a spot on the lake. In terms of the line to use, you need to have the best line for ice fishing in order to make the most of your time and effort. 
There are so many lines to choose from, which is why having a few pointers can help you make the right decision. Unless you are going for game fish which requires use of lines with a 10-pound test (breaking strength), the rest of the time a 2-4 pound test line should do just fine. 
Let’s have a look at the three basic types of lines:
Mono-filament Lines which are single strand lines that are abrasion resistant. For ice water fishing, in order to keep track of the line, colored lines are available.
Fluorocarbon Lines which are especially advantageous since they are virtually invisible in the water thanks to their closeness to the refractive index of the water. The invincible characteristic makes such lines ideal for clear waters. In addition, there is lack of stretch in such lines.
Braided Lines which braids add to the strength of the line and make it seamless to cash bigger fish. It is a lot easier to set hooks on braided lines. These lines have no stretch and can cast a mile.
Ideally, the line you choose should be able to retain its characteristics in the cold weather. It should be able to remain soft and flexible even in the cold water.
