I’ve used both. Glass is noticeably better on HD. Clicks are a little better on HD. HD turrets are splined instead of set screws. Parallax focuses closer on non-hd. Both track like they are supposed to. I got a good price on a used HD so it was worth it to me. SWFA’s Black Friday sale price makes it worthwhile too.

John

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
