Lightly used Kowa 60mm spotter with 30x wide angle eyepiece.
Glass is immaculate. 1lbs 14oz.
More compact and light than the Kowa 66mm with similar image quality.
$490 $450 shipped. I can ship same day as payment.
The 602 with 30x is 30oz vs the 553 at 28.5oz.
I do not have a 550 series to compare glass with, but the FOV on the 602 is 126ft at 30x compared to 132ft at 15x on the 553, thats nearly the same FOV at twice the power.
The 30x eyepiece is what makes the 602 shine here. The resolution is very good to my eyes, and I've used the larger 664 with the 30x. The 664 is obviously slightly brighter but at a size and weight penalty.
