This is a professional grade pigtail or corkscrew snap and swivel combination. Double welded rings, ball bearing swivel, rated at 450 lbs. It's ideal to use in a muzzle bungee for quick disconnection and attachment of the shooting line. It's superior to the more common coast lock snap which although often rated at the same weight, has been known to straighten out under load.

There's a general misconception that the the pigtail is difficult to thread the mono into. There are two reasons for this.

1. Most guys don't know the right technique. Once you get this rotating motion right it's very easy to do even with gloves. It then makes using the coast lock snap difficult by comparison.
2. Pigtail snaps from different manufacturers may vary in shape. In some the coil/pigtail may be pressing too hard against the stem of the snap, making it difficult for the shooting line to pass. This is easily remedied by pinching the main bend of the snap with pliers to create a little more separation between the coil and the stem. Pigtail snaps from SpearDIVER come ready to use and no adjustment is necessary.
