The Edge by Expedite Prowler Bait and Digital Caller is a deadly little caller/decoy combination. Bobcat’s just can’t resist this decoy. Set the main unit under your live trap and let the bird decoy protrude up inside the trap. The cats hear the bird sound, see the trapped bird and eagerly enter the trap. A break-away plastic bird is used to help with durability, but those trapped cats can be a bit destructive, so you can buy replacement birds at a very affordable price. The Edge Prowler Bait and Digital Caller can also be used in conjunction with foothold sets and as a decoy while predator calling. This caller/decoy will play continuously for approximately one week on a set of 4 AAA batteries. (Batteries not included.)
