A lower magnification means a broader view, which means it's easier to get your goals and stay around them.
Higher magnification means that you can view things further and may be more likely to observe or identify targets after obtaining a target. Although variable power ranges provide two options to some extent, it is more complex in optics, which means greater weight and cost.
You notice the drawbacks of these patterns: weight and cost. Weight: 19 ounces may not be heard in a gun shop, but when you're hiking your back or your rifle for three days, you may want to choose 11. Not only that, but the quality of the drill shaft on the rifle can't be improved, and heavy weapons are always moving slowly to your hands.
Most of us don't have an unlimited budget, so cost is another important parameter of choice. Deciding how much money you want to spend on your range is great, and how much you want to spend. Remember: while more expensive usually equals better, there are exceptions.
