3 out of 5 eggsNot good for stargazing

Pros: Permafocus is handy. 10x50 is a good all around utility binocular. These would be great for sporting events.

Cons: Permafocus does not work well for stargazing. It is difficult to see planets and stars with these. I returned them and got some I could focus instead. These would be great for terestrial viewing, but it's not what I was looking for. I also have a pair of 8x25 permafocus binoculars that I like better for terestrial viewing.

Other Thoughts: Nice, but not what I was looking for.

4 out of 5 eggsBird Watcher

Pros: Good solid binoculars, nice optic quality, durable rubberized coating.

I bought these for my mother as Christmas present for bird watching. They are nice for fast viewing of objects as they are always in focus.

Cons: Her biggest problem is that anything closer than 80 feet is not in focus. Most of the bird feeders she has set out are closer than that which means I need to get her a different set for the house. Thought about moving the feeders but moving the trees they are in has presented a bit of a challenge.

Other Thoughts: Mom sure keeps up with what the neighbors are doing these days. Since the focus is beyond her bird feeders. While looking at the birds she has a good view of neighbors 1/4 mile away.
