Now that you understand the basics of speed, you should know that depth is just as important. And many times, you may need to adjust your speed to hit a certain depth, or keep your bait at a shallow dive to keep your speed up.
As a rule, you won't need to go too deep for muskie. A lot has to do with how deep your bait can handle going. Driving crank baits and minnow plugs can dive as deep as 30 feet (9.1 meters), maybe a little more if you add lead to your line [source: Sternberg]. The deepest you can troll is dependant on how far under the water your bait can go before it falls apart or tears from the hook. In the end you're going to have to see what's working best on that particular day in that specific spot.
So, are you going to use a planner board or a downrigger? Not sure? Read on to see how these two methods work.
