The XRAP Magnum 40 is the largest in its series, plunging to 40 feet and maintaining speed at 12 knots. It's effective for various game fish like yellowtail, yellowfin, bluefin, and even wahoo. For wahoo, position it farther back and switch hooks to single inlines. Fishermen in northern California have successfully used these for bluefin and Nomad DTX's on schooling fish.
