The Yamashita Egi-OH K series is fitted with many features to help in certain situations you may face when jigging.
The Warm Jacket cloth is designed to keep the jig at the same temperature as a live bait fish. Research shows the squid see the bait almost like The Predator did in the movies, so having the correct warm glow will convince the squid it's a real fish/creature.
The 490 Glow, this statement is from the Yamashita site: Research shows the best wavelength of visible light for squid is 490nm. This is a tuned glow of 490nm which YAMASHITA discovered with the research from a leading Japanese university is the best glow color for the squids eyes to detect.
"Glow of 490nm wavelength is most perceivable for squid."
The Hydro Fin: Designed to keep the jig stable in rougher conditions. It is important to keep your jig straight without wobbling, the Hydro Fin maintains stability on the drop, especially designed for fishing in swell and tide.
