There are two models of KUREHA / KANZEN SEABASS SERIES.
・STEALTH GRAY ・FLASH GREEN
FLASH GREEN has visibility, so you can see exactly where your line is. So, I use this line for fishing cover.
STEALTH GRAY is less visible. I use this line when I worry about the fish seeing a fishing line underwater. If a fish sees your fishing line, it can get spooked and put off biting.
