Black Magic “TWIN SPIN” ball bearing swivels have an exceptional rotational capacity generated via an innovative design that gives both welded rings the ability to rotate independently.

STRONG – Heavy duty brass swivel construction coupled with a high strength stainless steel coastlock snap provides the ultimate in swivel strength and performance.

SMOOTH – Two rotating welded rings ensure that the swivel and coastlock snap will never twist and “lock up” under load, this sometimes occurs with swivels with only one ring.

BLACK – For a purpose, some fish species will strike at a shiny swivel while you are playing the big one.

PROVEN – Bruce Martin (skipper of one of New Zealand’s premier game boats “Predator”) trolled lures and livebaits for thousands of miles using our prototype “twin spin” swivels with outstanding results – numerous marlin, tuna and sharks were hooked with no line twist and no opened snaps.

TESTED – As with all BM products these are batch tested to destruction in their lab.
