This grim device is unsettling and very realistic. The wind howls as the convicted man stands on the platform. When switch is thrown the platform slams down and the body drops 18, thrashes violently and chokes. This is an intense effect and may not be appropriate for everyone. Includes two cassette players, 2 cassettes, 2 par can lights and amp with speaker. Requires 125 psi air compressor. Can be activated with optional foot pad or mnotion sensor. So realistic that a customer asked, Do you give him breaks, Does he get tired?. Stands 10 6 tall.
