The Select Grandex is a versatile and easy-to-use fluctuator for catching predatory fish. It has a pronounced own game, and it is not picky to the activity of wiring. At slow speed, the amplitude of oscillations becomes a little less and the lure sinks deeper, and at fast speed - wiggles widely, but does not go into a corkscrew, but only sometimes disrupts the game, which is often a decisive factor in the attack of the predator. This troll is suitable for searching for active pike and other predatory fish both in standing water and in moderate currents.
