GRIFFON BT covers up to a slightly deeper range than normal shallow cranks. It's a next generation shallow crank designed to target multiple shallow ranges from 0-1.5m (0-5ft). Its excellent obstacle evasion abilities and acrobatic prowess allow it to shoot around like a pin ball when contacting structures or the bottom, triggering reactions from bass. The area of the head that contacts water is much larger than that of past crank baits. The GRIFFON BT have bone body and tungsten sound.
