Floaters, divers, and suspending types. This bait comes in jointed models also. The jointed bait can be your preference. I have fished some and they were not my cup of tea. I will cover the floaters and divers first.
Some floaters have small propellers front and back while others have a cupped mouth like a pop'r.
This type of bait is used to jerk erratically across the top of the water. Sometimes just small jerks and let it sit will draw strikes. When fish are active this bait can be deadly. May. The bill type baits can be worked just like a crankbait. Slow steady retrieves or stop and go can produce fish.
