SQUID JIG WITH LIGHT! Catching squid just got easy with LED Squid Jigs. Jarvis Walker has used a proven squid-catching jig design and added a water-activated LED light to call squid from even further afield. It's a revolution in squid jig design and it works, especially after dark! Jarvis Walker LED Squid Jigs are available in four squid-catching colours in each of the size 3.0 and 4.0 models.
