Guru Bait Bayonets Our Bait Bayonets make changing tough boilie or artificial hook baits quicker than ever. Theyre a simple, twisted metal spike with a ring on the end, which allows it to be tied to a hair rig. To mount a bait, you simply push the bayonet into the boilie, right up to the eye. This will provide a secure attachment, allowing long, forceful casts to be made, safe in the knowledge that the bait will stay on.
