Planer Boards are designed to help fishermen cover more area, and reach places they would not have been able to reach by regular fishing methods.
Planer boards will carry baits and lures 150 feet or more off the side of a moving boat or
if anchored in a river or fishing off the bank with sufficient current you can send a spread of boards down
To increase or decrease the distance of the planer board from the boat, you can reel in the line or let it out more.
The Planer Board method of fishing is highly effective but still fairly unknown and underutilized.
