These squid combine the most effective technology methods developed by Yamashita, after years of research on squid. They feature a system of ball bearings that produce 600Hz sound, which is the frequency that most squid hear. On the side of the body as well as on their eyes they have phosphorus 490nm, the wavelength that most distinguish squid. Their cloth is a Warm Jacket, that is, it converts any light trace into heat, so that their temperature is higher than that of the water, so that they resemble a living bait and are immediately recognized by squid. Their cruise consists of steep sharp and dynamic movements. They sink at a speed of about 2.8 sec / m and have a pencil weighing 21.5gr.
