HookUpz Binocular Adapter
The HookUpz™ adaptor easily connects your iPhone 5/5S to your full-sized (32mm-50mm objective lens) Binocular.
It can also connect to your iPhone 4 using the included conversion kit. The HookUpz™ Binocular Adapter comes included with two interchangeable rubber rings that allow the adapter to fit most full-sized binoculars that have an outer eyepiece housing diameter between 40mm-44mm. Once you determine which ring works best, press firmly for a tight hold to the eyepiece.
Now you can take pictures or video directly through the "eyes" of your Binocular and easily text or e-mail friends. “Hook up” to your binoculars for hunting or bird watching or even law enforcement surveillance. Be sure to capture everything nature has to offer with the Carson HookUpz™.
