"Limey71"Thanks guys and thanks LDP because I've got my eye on a Vortex Viper which is a minimum paralex of 50 yards. Ted of 'Teds Holdover' reported that the image is clear at 10 yards, and as a PCP airgun user I was hoping I could use one on targets from 15-60 yards. People are telling me to find another scope that does, but I have my heart set on the Vortex with the XLR / EBR-2C reticle which are out of this world, but like most reticles of this kind tend to be on high powered rifles with a minimum paralex of 50 yards and this is why I put a post up recently if it were possible to alter the paralex to a shorter range than 50 yards.
