Occasionally, technological breakthroughs can change the fundamentals of how anglers fish. Recently, the use of forward-facing sonar has changed not only how anglers search for fish but even the very tactics used to catch these fish. Kyle and Britta Peterson have used forward-facing sonar since its introduction several years ago, and it's become a significant part of their favorite way to fish walleye. They find a large loner fish in outer space, somewhat related to but suspended far from traditional walleye structure, with a sharp shoot, a drop shot rig, and giant cow tongue-sized leech right in their face. In real-time, they can watch and work the fish until they trigger a strike. Trying to catch these fish without forward-facing sonar would be like shooting a duck blindfolded, but this powerful tool can turn average days into amazing days of fishing.
