Question: What is the size of the eye lens? standard is 1.25", some are 2". The actual size that your eye touches against.
Document: If I wanted to watch birds at 100 yds, this would have been fine. i was wanting to monitor elk herds at 1.5 - 2 miles. clarity not sufficient at that distance / magnification.
if you wear glasses you better plan to remove your glasses in order to use this scope. wearing my glasses the scope has about 1/5 of the view visable through the eyepice, but without glasses focused to bare eye right on it there is full field of view. other then that scope seems to work great as others have said feels cheap but you get what you pay for.
Tripod is worthless, optic is to lens heavy for it. Tips over in any position. Actually disappointed with this purchase. Doesn't focus well feels and reacts like a $25 optic. Box is very nice. All in all I believe the description is deceiving once you get the optic home. Spend lots of money on Amazon usually don't have thus problem. Shipping was great as usual from Amazon..
I ordered this spotting scope and the much cheaper Firefield 20-60 SE at the same time so I got to compare them side by side. I ended up returning the Barska for 2 reasons. 1. The focus was really hard to use and requires a lot of force. You can't keep the scope steady while operating the focus. 2. The magnification factor is misleading. To get the same 60X magnification of the Firefield, you would have to turn the Barska up to about 90X.
I bought this because of the magnification range and the price. It looks cheap, feels cheap, and the front lens rattles. The case is fine but the tripod is pretty weak. I bought a $45 camera tripod at Best Buy to use with it instead. I also read a lot of reviews that said that there is practically no eye relief. There isn't much eye relief at higher magnifications, but I only use it 75x power and below. I think I didn't really need the extra magnification.
To focus, you twist the huge objective lens! You can't see well enough with the scope shaking while you focus to tell if it IS focused. So you have to twist, check, twist, check, etc., until it's focused. Takes a lot of time.At high powers, the focus is nearly impossible to get right.The actual glass in the objective is less than 70mm.
I bought this thinking it would be alot better then it is, but i was really dissapointed with this for the money. I knew it was not going to be top optics either, but the only setting that was even halfways decent was 25 power. As soon as you tried to zoom higher then 25 power, it reduced your field of view right down to where really there was no wiew to speak of at all.
The scope was of poor quality, difficult to operate and had horrible optics. After using for 10 minutes, I had a migraine that did not completely go away for 2 days. It was packed with nice features but the optiscs and quality were poor.
It is unfortunate that this product did not work well for me. Barska puts out very good products and I may have gotten a defective one. It would not focus at 25 yards and I figured it was me doing something wrong. However, the following weekend I went shooting and set a target out at 100 yards; again I could not get scope to focus properly. Like I said, maybe I just ended up with a defective item.
For the money I paid this is a great value. I do wish however that the eye relief was better, you have to take your safety glasses off to effectively see your target.
