Thanks, I have just bought a 470s off a member here. I already have a 450 but a few here commented that the 470 was better on a centrefire. The 450 gets a bit pixilated over 7 power. But I love the clarity on lower magnification.With the n470S? I did use to use a solaris srx but the onboard is very good. Only issue i found with onboard was it whiting out very easily on close grass etc & couldn't adjust obviously. But with the solaris it was perfect. One night I detected heat signature what I knew was a way off but couldn't tell much of anything. Through yukon, I could see they were neighbours horses, able to tell which was which, which was eating- if they'd had name badges on I'd have been able to read them!! Google maps said it was well over 700yd. Fantastic nv unit.
