Phone Skope for sheep hunting

I have been using PhoneSkope adapters for a few years now. This has been an immense help in judging sheep (and other animals) before making a stalk. This pic is the Vortex Viper HD 15-45x65 coupled with the Phone Skope and iPhone. Saw these two rams from a few miles out and was able to quickly determine they were sub-legal, and saved myself a lot of steps and frustration.

Recommend this to anyone that has a spotter and phone.
