I bought this range finder for hunting and shooting, I plan to use it to determine the distance to the target and help me measure the distance roughly by eye as well Patterns to create for my bow, arrows and shotgun. The rangefinder has adjustable focus on the lens you're looking through kuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuically to it and only vibrate for a click when it's on. The only thing I don't like is that the buttons are one on the side and the other on top, for me it would be easier if both buttons were next to each other, but that's my personal opinion and preference. Came with a nice soft case and the battery can't wait to take it up north!
