Bought a Fish Finder

I recently purchased a cheap Lowrance X4 Pro fishfinder unit to put on a canoe/kayak when fishingfor yellow perch and crappies on Lake Orange. The X4 Pro has a 60 or 120 degree sonar that automatically switches according to depth, this way, you won't be looking at a 5x5 foot area in 7 feet of water. Hopefully I will be heading to Lake Orange this Saturday to try for some yellow perch and possibly my first walleye!
