Double D (a shallower cousin of the Triple D) is actually a Jerkbait in Disguise. ERC has combined the roll and flash of traditional crankbaits with darting, gliding action of jerkbaits to produce a truly multifunctional lure that excels in many casting and trolling applications. The secret to the Double D is its near neutral buoyancy. This characteristic allows pauses that keep the lure in the strike zone longer and triggers neutral and inactive as well as active fish.
