Please for advice, I shoot with an air rifle at 10m, the black circle is 3cm. Which telescope is the best of these so that I can enlarge the black circle 3cm, at 10m from where I shoot. Thanks.
I would think any cheap Chinese spotter would work well at 10 meters. I'd look at ta 10-30x or 15-45x instead of the 20-60x for crisper image at such a close shooting distance.
