Phone Skope's, patent pending, C-4 Optic Universal Adapter was created to make using the Phone Skope even more simple! The features of the C-4 include a ratchet-like, spring loaded, detent (catch/locking) mechanism that uses small plastic "fingers" that twist in and twist out creating a solid mount to most optics. The connector fits optics from 1.70" in diameter to 2.335" in diameter.
This is an all in one kit that will have you set up in no time! Included in this kit is an iPhone 4/4s Case and an C4 adapter to fit your spotting scope. Built out of very strong ABS plastic, this will handle a great amount of abuse and still protect your phone. We at Phone Skope have put them to the test, rain or shine they will impress you with crystal HD video!
