I'm looking to buy a spotting scope and can't make up my mind.I've looked at the therons,and vortex.I've just started looking into the fieldscopes offered by Vortex and Nikon.Does anyone on here use a field scope???They have less magnification but are super lightweight and small in size for backbacking.The vortex razor fieldscope is like25 oz. and 10 1/2 long.I'm leaning that way due to size and ease of packing.But, am I losing to much in its viewing capabilities?I'm hoping some on here have used one or have one of their own.Nikons version is the ed50 fieldscope.Is this going tohave enough power to locate animals far off or are they no better then 10x42binos.Don't want to save weight and space only to have a scope my binos could do just as well as.The specs for the razor are 13x33x50;Nikons are 11x30x50
