Brunton F-ECHOZOOM overview

  • 1Description

It's so small you'll barely notice it in your pocket or bag, but the 10-30x21 Echo Zoom Monocular is equipped with optical elements that deliver big performance. Its BAK4 prism glass and fully multi-coated lenses minimize reflection and maximize light transmission for a bright, sharp image. At 10x, the Echo Zoom yields a respectable field of view; zoom in to 30x to see distant details clearly. You can mount this monocular on a tripod to eliminate image shake at higher magnification, and for comfort during long-duration observations. Along with its long-distance capabilities, the Echo Zoom features a 10' close-focus distance with applications in nature observation, art galleries, and museums.

At just 4.2 x 1.4" and 3.2 ounces, this monocular is easily carried and takes up little space in a glove box or pack. Its rubber eyecup folds down to accommodate eyeglass wearers. A lanyard and carrying case are included.

    Brunton F-ECHOZOOM reviews

    10-30x21 Echo Zoom Monocular is rated 4.0 out of 5 by 13.
    Rated 5 out of 5 by from Great Monocular I got this as part of my gear bag, always good to be able to see far ahead. Optics are good, solid clear image. Zoom is pretty awesome, amazing how close you can get with this little thing. Just understand if you are not familiar with high zoom, and small diameter optics, you will need to keep very still the closer you zoom to avoid image bouncing around. Comes with case and one sense cover. Wish it came with 2 covers, one for back as well as front, but this is by no means a deal breaker. you get a lot for the money with this one. haven't tested in rain or humidity, could change the number of stars. but for more ideal weather, this has been great so far.

    Rated 5 out of 5 by from Best small variable-X scope available. As a former military long-distance shooter, I'm very familiar with optics of all sorts. Even though it's small enough to fit in the palm of the hand, the Brunton Echo is a fantastic piece of optics. For a scope with such a small objective lens, it provides extremely clear views and the zoom is very smooth. I wish I had one of these when I was in the field; it would have been a great intermediate option to a full-size spotting scope.

    Rated 4 out of 5 by from A Good Cheap Backyard Birding Scope I use this scope with a tabletop tripod to watch the winged visitors to my backyard. Its easy to use, has a large, well knurled soft rubber focussing ring, and zooms from X10 to X30+, though more than X10 seems like a microscopic view at 10 yards or so.The downside: 1st, the optics are not colour neutral and put a slight yellow cast over every image. It's not terribly bothersome, but its there. 2nd, this monocular is not terribly bright. In photographic terms, I would guess that it steals at least 6 f stops, maybe more. On very grey days or at sunset, its pretty useless.3rd, the minimum focussing distance seems to be about 25 ft, give or take. That doesn't seem like much, but if you are strictly a backyard naturalist that might be a problem. I had to move back 10 feet from the window to watch one off my favourite feeding stations.Don't let the downsides I list put you off. If you want a sub-forty dollar scope, I still think this is a contender. Its coated optics virtually eliminate lens flare, and its images are crisp. It focusses very easily, and if you need the zoom, it as easy as sliding a knob. For the price, I think it's a good deal.

    Rated 3 out of 5 by from It's OK, but only for the price. For the price being asked, this is an acceptable monocular, but I think my expectations were a little high. Going much past half of the zoom and the image becomes so dark, it is not much use. I would not suggest trying to use full zoom without a tripod. The image also becomes unclear and difficult to discern at high zoom, probably helped with a tripod, but not completely fixed. Operation of the zoom and focus collars is smooth and easy. It feels well made, and at the lower zoom range seems reasonably clear and useful. Feels like it would have been prudent to stop at 20X or so.

    Rated 3 out of 5 by from Zoom isn't a good idea This is an inexpensive monocular and the image quality shows it. Very bad image quality at 30x -- enough to make it unusable. At 10x the image quality is acceptable, but because of the zoom the field of view is very small (aka. tunnel vision). I would recommend instead getting a fixed-magnification 10x monocular for a better field of view.

    Rated 4 out of 5 by from Works well I go this monocular to spare myself the wieght of binoculars when carrying photographic equipment. It works well although you need to use a mono-pod at higher magnafications. It is a well made sturdy tool.

    Rated 1 out of 5 by from Would not buy again should have returned. I had high hopes for this monocular but it fell way short. It is hard to get a clear view because you have to hold it away from your eye. The zoom does work but it is not viable when zoomed due to the extremely narrow field of view.

    Rated 4 out of 5 by from It's a great tool Small and compact and light in weight, it makes for a quick read on what's happening outside.
