"Jigging 10-14"

First post here, trying to get better at offshore fishing. However I fish natural lakes up here in NY. Guys who win our points tournaments usually sit in 10-14 feet of water and use jigs. They just throw them in pockets of weeds 2-3 feet in front of them and jig. Just curious if anyone knows what kind of jigs are best for this or know what they are using. I don't think they are using football heads. Just wondering if anyone else uses this technique.
