Steiner anti relective device (ard) - Steiner ARD Anti Reflective Devices Set - Pair

The ARD works wonderful. In some cases it may make your viewing a little dark, but with mine I did not notice it. One thing to remember, the ARD comes with an allen wrench. When you have your ARD installed correctly, you will see a small hole on the side of the ARD. Thats where you insert the wrench to tighten it down!! Now it does make the binoculars a little longer and may not fit well. The case that came with my 10×50 Military/Marine works just fine.
