I was first thinking of buying Flir RS scope, but then found that they have lower charasteristics than compatible zeus scope, first of all lens's size. Moreover zeus has more software features which I at first time was very sceptic about. And I really wasn't sure about FLIR battery compartment decision, 4 hours of life for that solid battery and then go and plug it in into a tree, no thanks! ) Plus I really loved that sandy color from opmod, would recommend with no doubts.
Pros: lens size, external battery source, software features
Cons: small buttons
