When I started target shooting way back in the 60's, all I could afford was a Bushnell Sentry. It did its job and I still have it. Then as my eyes needed more light and power I bought a Bushnell Spacemaster II. It did its job for a while and I still have it. Now I have bought a Carl Zeiss Diascope 85T*FL with a 20-60x eyepiece. I set up the Zeiss and the Spacemeaster the other day on my 100m range and looked at the same target. The Bushnell showed a yellowish target while through the Zeiss the target appeared white. Goes to show that you shouldn't save on optics(or shoes), unless economic circumstances say otherwise.
