I found this great link for riggging these effective lures. I like it to keep from loosing these high $75 lures.
Quote from link:
"The Mann’s G50+ is the deepest diving lure available. Mann’s claim that at 4 Miles per hour with 200 feet of 80 Pounds test line out it will dive to a depth of 50 feet, even deeper on lighter line or superbraid.
This makes it a useful addition to any offshore arsenal for those days when fish are holding deep. Tuna, wahoo, marlin and sharks will all hit it but the Mustad double hooks supplied as standard aren’t strong enough for tackling the real big guys. Here’s how to rig the Giganticus to tackle anything that swims.
