Plenty of info out there on jerkbaits. You can search this forum or just do a google search. Jerkbaits are something the pros use alot more than weekend fisherman. They are hard to beat and sometimes unbeatable but there are also days when they just dont get bit period. Similar to Jigs. Clearer water is key 3ft visability minimum for a good jerkbait bite. Wind also is a big key everyone agrees on. Clouds are important depending who you ask but I personally feel if its windy clouds arent a huge factor unless its really clear. Cadence and how hard you jerk and how long you pause are key also. So is getting a jerkbait that gets to the right depth. Gotta have a suspending one when water is colder and deep diver when its really cold and fish wont come up for one. Another key I picked up on the last year or two is you need to jerk the american made ones harder than japanese ones. I use a medhvy rod with my rouges or jerk a med rod hard and use a soft rod and more subtle jerks with my lucky craft baits. But I could go on forever about jerkbaits just look around and you will find plenty of info.
