The antelope decoy have been proven to be very effective. Robotic head and optional swivel base ( additional $1050.00) is a lethal combination. Antelope have very fragile hides so obtaining a hide that doesn't slip can be challenging. We recommend the customer have the hide tanned prior to sending them to us. CRW is able to find tanned hides at certain times of the year, hides run approx. $600.
