YAMASHITA has investigated the relationship between squid and temperature, finding that squid perceive and react to temperature. The "thermal skin" developed by Yamashita can absorb heat from sunlight, a lamp, etc ... and transform it into thermal energy around +0.5 to 1oC above water, achieving total realism. For many years, squid fishermen around the world have relied on bright colors. Now, research developed by Yamashita shows that the best wavelength of light visible to the squid eye is 490nm. Yamashita has discovered that squid can pick up sounds of frequencies between 400hz and 1400hz, 600hz being the most attractive level. With SEARCH technology, steel balls are incorporated into the egi that, when colliding with plastic, reproduce the noise of cephalopods when biting. A twist on the classic EGI SUTTE R, adapting to new times and respecting the environment, thanks to its new ecological counterweight instead of the traditional lead.
