I normally jig through the ice or from a boat be it anchored or drifting. I like to just sit back and let my lure bounce up and down off the bottom. But, sometimes fish are higher up and I try to keep it in around the range they are at. Ie.... like lake trout may be suspended in 100 feet of water and just hanf around 7o feet, it would do me no good fishing the bottom in those cases.
