I recently acquired my first rifle and topped it off with a Zeiss 3-9 x 40 w/ Z600 reticle. My next purchase is a spotting scope and am looking at a Vortex Nomad? I think I am convinced this is the glass I want for the price range I am in (taxes in $447) Canadian prices. As for a range finder 1. do I need one and 2. are the cheap ones like a Tasco 600 on sale for $99 from $200 good enough or do I have to go a little up the scale to min. $300 any suggestions or am I just wasting my money?
