Switchback Vibration
I have a Mathews Switchback that I purchased newlast spring of 06'. It is a 60-70# bow with 80% let off. It is set at 62#. I was shooting with a buddy of mine who shoots a legacy. We both noticed immediately that my switchback was very loud compared to his legacy. There was a loud twang or hard vibration emitting from my lower cam. My buddy held his ear within a few inches of my lower cam while I pulled the string back just a little bit and let it go to try to create and pinpoint the noise. It was very obvious that the lower cam was vibrating bigtime! Does anyone know what my problem is? Any solutions or suggestions would be very much appreciated.
