I am very happy that I bought this binocular; I bought it for our first charter trip and the binoculars provided with the boat were really bad. Compared to those, these were shining. I think they were also much better than the Bushnell 7X50 we had during sailing school. Actually with these it was the first time I could enjoy watching the world through a pair of binoculars. The image is clear and very bright. It doesn't seem to lose any brightness at all. They are not very heavy, if you hold them in a position with your arms close to your chest to provide more support you can use them for quite a while. Now, the bad - they are not extremely well built; the rings around the lenses are stuck with some very cheap glue and they almost came off in only a week of using it. This doesn't have any effect on the optical quality, but still; I hope that the inside is built somewhat stronger, otherwise I will have to replace them too soon. They have separate focus adjustments for each eye, which is good if you have different vision in each eye, but the correction rings are too lose and the slightest touch moves them, meaning that you have to adjust focus again. The built in compass is fine, well visible during day or night using the red lamp included. It was also accurate, as we compared it to three other compasses and they all showed the same bearings. The biggest issue I have with this binocular is that the extremely high eye-relief number claimed by the manufacturer, (24mm I believe) doesn't seem accurate; normally 18 is a good number, and 20 or 21, exceptional. Celestron claims that this one has 24mm; I choose this product based on the eye relief because I wear eyeglasses and I wanted to be able to use it with them on; well, not much luck, because the field of view is so drastically reduced when wearing my glasses, it's not worth bothering. Actually I think it is about 18 because this was the number on the Bushnell that I used and I have the same field of view with this one. Luckily, I realized soon that if I remove my glasses I am still able to see clearly without needing to adjust the focus, so that's what I did. During one week of use something happened to the scale and compass window - it has somehow rotated so that the compass reading does not show through the window it is supposed to; also the distance scale is not vertical anymore, making it totally useless. I suppose I have to open the compass housing and fix it somehow, but I am not sure how and why this happened. In any case, I suppose it shouldn't have, so this takes away one star. The other is lost because of the focus adjustment rings which are too easy to move involuntarily. All in all I am happy with the purchase and would recommend it with the above mentioned caveats.

Nice entry level marine/navigation/range finding binoculars ...
At first, I was skeptical of all the features at the price point it was offered at compared to similar offerings costing many times more. I read all the Amazon reviews and visited Celestron’s website to make sure I educated my self on reticle/compass binoculars. I was pleasantly surprised upon opening up the box. Pros: 1) Clean bright optics with no aberrations. 2) Robust yet light in hand. 3) Center focus capability... especially nice if you want to share without readjustment unlike other models. 4) The compass is fluid filled with good dampening... and accurate. 5) With supplies batteries, the night light for compass reading glows a cool blue hue. 6) Nice case, lens caps and strap. 7) Razor sharp Mil reticle.. conversion chart is in lens cap. (Reticle and compass in right eye.) 8) All function feel tight with no slop. 9) All seals seem solid and water tight. Cons: Only one thing keeping me from giving 5 Stars: You need to angle the binoculars up a few degrees And find the sweet spot in order to see the compass dial in the eye piece. But at this price point, I can live with it.

Received these yesterday, as I have only had a slight chance to test them out I can only give first impressions. Optical quality, very, very good, not perfect but very good especially for the price. (5 of 5 stars at this price point) Build Quality, Fantastic, they feel very sturdy, they are covered by a rubber armor and they are completely waterproof. (5 of 5 stars) Comfort, pretty good, a bit stiff but I expect them to loosen up over a period of use. (4 of 5 stars) Instruction manual, with these Binoculars, there is some math involved to get the size or the distance to an object. While the instructions were adequate, they were lacking a bit. (4 of 5 stars) Accessories (lens caps, binocular bag), This is a double edged sword, the bag is great I expected to get a very cheap case, what it came in is a well padded rigid soft case that well exceeds my expectations. The lens caps...not so much, the front caps are great, they are connected to the the body so you won't loose them. The rear cap is almost worthless. It is a single cap designed to go over both but can't be fitted securely. (4 of 5 stars because of the rear cap) Compass, Unfamiliar with nautical compasses I was a sort of surprised not to see a N or an S or an E or a W. But after 5 seconds I was able to deal with degrees... The illumination was great and its easy to read. This is a great way to know exactly where you're looking at any time. The compass, integrated with the rangefinder is a huge plus to me. (5 of 5 stars) I really like these binoculars, I am hoping they live up to my expectations in long term use. I'm taking them out this weekend to test out a bit more and see if the rangefinder is true in its readings and see if the optics are as good as I think they are.

No central focusing control
This is a robust and well made set of binoculars. The heading indicator, which can be illuminated., is a great feature. The only slight downside is that you have to focus each lens individually.

Worth buying it's vision is very claer but it is too heavy

Good product for good price
Optics are very good, appreciated the reticle for estimating distances, like many others have identified a bit difficult to view internal compass reading when viewing object.
