One of the best things to do when trying a new lake for the first time is to get a paper map and study its contours for possible areas for big pike and muskie. You don’t really have to switch gear to fish for both at the same time. Pike will attack anything and almost all the time, while muskie do not necessarily need a 10 or 24 inch bait to get them to bite.
Next best way to get to know a lake is to troll around, get your lines wet and watch your fishfinder for quick changes in the lake bottom. If your boat is equipped with GPS or you have a handheld device, start marking potential spots to come back to and cast. If you have neither, pick up some bouys to drop down, don’t want to spend money, or a lot of it, tie up some milk jugs with a 4 oz lead weight, if its windy double it up to an 8 oz.
