I had a rigor rabbit for a while and did not care for it. It just did not have the "rigor" i wanted...i returned it and went back to the old coonskin cap hanging in the brush.
Yours has the plastic can inside with the motor and spinning weight? That's what mine was and it just vibrated around without much real motion.
I have a system I use in Whitetail hunting during the rut that seems to work for me. When I make a mock scrape in the area I wish to hunt I will place a couple of 35mm
film canisters (film removed of course) in the scrape after I have cleared out all leaves and other debris. The film canisters are filled with cotton balls and saturated with doe in heat urine. This keeps the urine from soaking in the ground and can be refreshed on each trip if needed. I will also use the tarsal gland of the buck...
