The more I think about this topic the more complicated it becomes.Things to think about are the type of calls your using.Loud calls reach out more which is good in some cases but if an animal is approaching or hung up tone it down a little if you like them closer.When hunting alone I think the chances of calling them in close is better than when hunting with a partner.Reasons for this are more scent,more light usually two shining in two different directions,a larger visual target for the critters to pick up on.possibly more noise.I'm not saying that two guys hunting can't call them in close but you really have to have your act together and that usually only happens when both are experienced and have hunted together before and know how to communicate to each other and how they are going to react in certain situations.So what to do if you like to hunt with a partner and your not a confident long shot or have trouble identifying at long range.The easy solution and least expensive would be to hunt alone.But its fun to hunt with others at times so you better be prepared for longer shots.Things needed for shooting longer distances,better optics,9 power minimum.Good lighting,not just illuminating eyes but bodies at long distances.And a flat shooting rifle capable of a lethal shot at long ranges.Also a good gun rest is probably needed because most of us couldn't hit a fox at 120 yards freehand on a consistant basis.So I quess it boils down to this.What type of hunting do you have where you live.If you live in the mountains with lots of brush the good news is you don't need all this gear but if your a flat lander especially one that hunts with others you better be prepared for the long shots or get use to seeing those eyes just out of range and not being able to identify or make the shot.
