MODEL SD 8X42 WP

You have to look close at the S-Se­ries to tell it apart from the Z, but there is a more pre­cise build to the Z, and the S-Se­ries doesn’t ad­ver­tise the mag­ne­sium-al­loy frame.

IN THE BOX: Comes with neck strap and ny­lon padded car­ry­ing case with strap. CON­CLU­SIONS: It’s tough to un­der­stand the wide price dis­par­ity be­tween the S- and Z-Se­ries when the op­ti­cal clar­ity in our test re­sults were so sim­i­lar. The ZD seems to have a more rugged “feel,” such as in the ratch­eted eye­cups. The S-Se­ries ap­pears to be rub­ber ar­mored poly­mer rather than ar­mored me­tal as on the Z. In the 25-yard tests, we could read most of the bot­tom line of the eye charts in bright and dim light, and half of our testers could read the whole bot­tom line in bright light. At 100 yards, the SD could read line 7 like the ZD, and we couldn’t de­tect an op­ti­cal ad­van­tage to the more ex­pen­sive Z-Se­ries. The in­ter­nal fo­cus was quick to ad­just, but the right-eye oc­u­lar fo­cus ring be­low the main fo­cus dial was awk­ward.
