BUMPY is developed for linear fishing and designed to give off a very precise range of vibration. The tail starts vibrating gently at very slow speeds when you need to slow the lure right down to get a take. Fished faster the tail vibrates more strongly and the lure starts to roll. We use a lively rubber that is supple yet solid. The outline is proportioned to exactly mimic a prey fish. BUMPY is a real perch and zander magnet and suited to Texas hooking with a stomach and dorsal cavity. Super versatile this lure has caught fish in all sorts of different conditions. This 4x4 nature means it always has a place in our lure boxes!
