IPD is an acronym for inter-pupillary distance, how your eyes are spaced. The DTNVS IPD Stops Kit can be installed by the end user without special tools. The IPD Kit allows the DTNVS optical pods to stop at a pre-set position adjusted by the stop dials.
We are currently out of on hand IPD Kit inventory. We expect more shortly. As soon as they arrive we will move through orders for fulfillment.
