Frequently Asked Questions

The Prowl has 2 focus controls, a diopter and a wheel at the front of the device. Use the focus wheel at the front to bring the screen into focus and use the diopter to help your eye see it as clearly as possible. You may also wish to use the diopter so that objects appear the same size with both eyes.
