[QUOTE="4ked Horn, post: 79679, member: 11"] Porro prisim and roof prisim are not really subject to being called better or worse. They serve some different purposes. Roof prisms allow a more compact design while porro prisms provide beter depth perception. 10X should be sufficient for 800 yard viewing and scanning but might fall short on spotting actual impacts. The famous sniper Carlos Hathcock used a 10x scope for many many long range shots so it should get you by just fine. 50mm Obj lens will help with the low light viewing. Good choice here. If you want to supplement your optics with something very compact for quick mid day scanning then also buy a $20 pair of bushnell or tasco compacts. You know, the ones that look like two toiletpaper tubes connected with some duct tape. Get a 7x21 or 7x25 and don't spend alot of time looking through them or your brain will explode. No one owns variable power because they are built like crap. If you try to zoom two lenses at exactly the same rate for less than about $600 the quality will make you wish you followed the crowd on this decision. A spotting scope and a rifle scope can zoom nicely because it dosen't have to be EXACTLY in sync with another parallel optic. It is hard enough to have a simultaneous focus in both optical halves. That is why we have a diopter adjustment. If you think cheap binoculars are bad for your eyes. Spend the day looking at the same object at 10x with one eye and 10.2x with the other eye. Your eyes will fall out of your head and turn to ash when they hit the ground. [/QUOTE]
