Below is a review by AstroBackyard of the PL-1 in action. Thanks to AstroBackyard for allowing us to share this review.
(Note): There is a slight error in assembly of the PL-1 in this video review. One bolt was not properly inserted in the center of the main upright support of the yoke. This causes the yoke itself to be less stable and will not allow the user to level the binoculars as intended.
