A Serious Lure for those Seriously Big Fish. The Big B52 is popular in areas such as the Queensland impoundments and the Runoff in the Northern Territory but can be used to great effect in estuaries, coastal waters as well as off shore waters. The Big B52 has all the characteristics of the B52 and can be trolled at speeds up to 6 knots but is more comfortable at slower speeds and working the lure by twitching the rod tip.
