I have tried many different types of bino's including swarovski, zeiss, Tasco EXP, and Loupold wind river and I trust the Loupolds the most I took them hunting with me and I got anoyed because they could see deer way before the sun thought of rising and my rifle scope couldn't. The loupolds are crystal clear, let in a tremendous amount of light, they are armored and are of superior quality, I love them. I am using 8x42 roof prism wind river Loupold binos, in my opinion they are the best.
