The 8x21 UCF R from Pentax is encased in a durable rubber housing providing a firm, comfortable hold and excellent shock-resistant performance.
Innovative Dual-Axis Eye-Distance Adjustment System
The dual-axis eye-distance adjustment system makes it quick to adjust the distance between two eyepieces, ideal for sharing the binoculars with someone else.
