My family bought a cabin in Mid Michigan on a 280 acre bowl shaped lake that is loaded with cabbage weeds all the way around the edge out to 12 feet and then drops to 28 feet in the middle. It has a ton of Blue Gill and Crappies. I am thinking about picking up a Marcum M1 flasher to help locate fish in the basin kind of like how the guy in the video below does. Is his technique and setup a good starting point and plan? It will be me, my 13 year old son, and brother-in-law. Also, any recommendations on rod, reel, line brand and size, jigs, trailer, etc.... Just trying to get the basics. Would like good stuff but not crazy expensive. Thanks for any advice.
