Overhead reels are designed to be used off boats or kayaks, where no cast is required and you simply drop the line down beneath you. They are also used for trolling from a boat. They are very similar in design to a baitcasting reel, in that they have the spool facing the same way and the reel is positioned on top of the rod, rather than underneath. As with other types of reels, you can get Overhead reels in varying sizes. The spools on Overhead reels have a lot of line capacity, which is required if you are fishing on deepwater and need to drop your bait down to the bottom. The drag systems on Overhead reels are mostly very well designed and robust, they need to be with the potential battles they will be up against. You can find two main types of drag levers on Overhead reels. The first is the star drag, and this is usually a 4-point lever that is positioned directly behind the handle. You simply twist the lever to either increase or decrease the drag. The second type is the single thumb lever, with is positioned on the same side as the handle, but moves back and forwards around the reel. These tend to be found on the larger Overhead reels.
