Question: Does it have a doppler? Thanks Tom
Document: I have wanted one of these scopes for watching and identifying birds, this one is perfect and priced nicely. Thanks!
This scope is great for watching the birds in our front yard. They stay about a hundred yds. out to keep away from the cats but the scope brings their images close to be observed. Thanks,  ... A  Patriot
Worst thing I've ever ordered. Should have been in a box of cracker jacks as a prize. Even then I would have been disappointed. I gave it one star because amazon wouldn't let me use 0 stars. Thanks. Jeff j Carlton mn.
Besides getting this thing at a steal, thanks Amazon! I really like it.It's perfect for the indoor long ranges. The mini tripod is perfect for setting it up next to you in the little shooting booths. Helps me see my patterns on longer shots and allows me to use the cheaper non splatter non neon targets. It's small, lightweight, fits in my shooting bag easily. I also picked up a larger tripod at GoodWill and will try it for outdoor shooting when weather permits.
you need a telescope for short distance, it will do the job but it does have limitations and don't expect to see the optical quality you get with a more expensive scope.
you better not expect much from this so called spotting scope you will be lucky if you can see anything closely  after 50 yards
worked fine, tripod was of no use, to small.
with out a doubt this is a great spotting scope its very light weight about 1 1/2 lb. it includes a little carrying case for the scope and it also includes a small table tripod. i really like it and use it to spot nature.
waste of money. when buying optics spend money to get something worthwhile. Can't see anything over 25 yds. However I do have a Barska rifle scope on my AR and its just right, but the spotting scope is junk
wanted to like it, but can't. it is only a closet cleaning away from being thrown in the garbage, and I don't even have the money for a replacement.
Answer: yes
