New to the site and looking for some advice. I'm looking to upgrade my older 8x40 monarchs but I'm at the point of information overload. Locally I've handled the Vortex Talon & viper, meopta meopro,nikon monarch & steiner predator. Anyone have any experience with Doctor 8x42 and how would they measure up to the others? Primary use will be deer i.d. in low light. Size or weight are not a concern. Would like to stay within a $600 budget. Thanks for any advice.
