The Zonk is like no other lure. It has a carbon beak that emits a vibration that you can feel right up through your rod, especially if you use braid. It also has a hole through the top that creates a displacement of water that predatory fish can see (according to Japanese experts!!).
Another feature is when you stop winding it levels off and then sinks backwards slowly, therefore if you have fish following but not taking just stop winding and drop the rod tip for a few seconds. It has a very aggressive zigzag at most speeds of retrieve and casts a very long way indeed due to the tungsten weight transferral.
Excellent service reasonable prices fast shipping and very professional.
