BOOYAH Covert Series After years of testing and tweaking, pro angler Jason Christie has finally designed his perfect spinner bait. The unique head design is modified from a traditional BOOYAH spinnerbait head with a raked out gill, which offsets the blade torque to keep the bait running true. Featuring select head and skirt colors, as well as high-quality Hildebrandt blades, this spinnerbait is truly a viable all-season option for anglers looking to toss spinnerbaits in any conditions.
