A close crossing with an inbound ship on the outbound side of the shipping lanes (and a mile outside of the wrong lane to boot) reminded me that it isn't enough to know where you are, and assume ships will stay in their designated lanes. Not only do you need to see them clearly from a distance, you need an accurate bearing to detect potential collision course. It was this incident that drove my decision to buy this piece of safety equipment without delay.

I was very impressed when I took these glasses out of the box, they have a solid, high-quality look and feel -- from the optics (clarity is awesome) and adjustments, all the way down to the case they come with (padded, solid closure, orange trim for visibility at night.)

Perhaps the feature that lets the Celestron Oceana stand toe-to-toe with much more expensive models, is the quality of its built-in bearing compass. Liquid dampening is a must, out on the ocean, without this a compass is nearly useless. More, I checked its accuracy against the fluxgate compass built into my GPS, it's exactly on. And its backlight is ideal, the compass is easy to read down to the degree, day or night.

I did have a tiny bit of difficulty seeing the compass at first glance, but quickly realized that the rubber eye cups and my nose were keeping the lenses a little higher than desirable. Very slight downward pressure corrects their position.

Over all I'm very pleased with the purchase, and given the Celestron no-fault lifetime warranty, I'm sure I'll be using them for years to come.

These binoculars offer a great combination of features for the price. The built-in compass is a very valuable on the water, and the backlighting works very nicely in the dark. Eyepiece adjustments worked very well for me and produced crisp viewing. The rangefinder scale is easy to use and may come in handy.

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.
