These chuggers are gonna be used for saltwater fishing--the especially seem to attract the big marlin. And, this lure is quite famous: it has pulled in over 80 world-recording earning catches over the years since its creation. The beauty of the Super Chugger is it's shape: the cup shaped head allows it to rise and fall, and still survive in rough waters. You can pull it fast or slow, but it works better at a slower speed. With these coming in small, standard, and senior sizes,as well as in a large range of colors (see Image #3), there is a lot of variety in what you can fish, but you gotta remember to adjust your weight line as well. 200# will do for standard, but 300# range is better for the seniors. As for color, blues and blacks might pull in the Marlin. Another key thing to remember is that you wanna hook the chugger way back in the skirt so that you'll be able to get a proper set on any bites. The video on slide #4 can show you how to do so. I've only fished the seas a few times, but these have always come along on my buddies' boats.
