    Maven diopter?

    When you say wandering diopter, what do you mean exactly? I have B6 10x50: The diopter ring is super stiff, difficult to turn in a good way. I don’t think either the ring or the setting wanders at all. The eyecups, however, wander to hades and back all the time (lucky I wear glasses and don’t...

    Binoculars around £1000

    Congratulations in advance of getting great binoculars! After ringing my hands for many many months and after trying Vortex AK UHD 10x50s, Maven AK 9x45s, and Maven B6 10x50s, I chose the B6s. I’ve been actively birding with them for over a year now and I have been super grateful I made this...

    Highest quality 10x50 central focus porro?

    At least a year ago I decided 10x50s were what I most needed in my bird watching life. I did try Nikon HG 10x42s and they underwhelmed me greatly. (I own HG 8x42s and I bet 10x50s would be awesome.) I tried out the Maven 9x45 AKs and I found them nauseating to pan with as well as heavy. I...

    Ultravid 7x42 HD+ vs Noctivid 8x42

    I would have thought 50 mm objectives will always outdo 42s, but on a recent xmas birdcount I tried another birder’s 8x42 Swaros (I don’t know what model) while they tried out my 10x50 B6 Mavens. The Swaros were brighter. We both noticed this. I love my 10x50 B6s, but now I’m all like...

    Maven 7x28 review

    The phrase and the idea of a “…freak sample” in a positive sense literally made me laugh. You received the opposite of a defective item. What word would describe that? It was hyper-effective, maybe? 🙂 Serious question: If you have super awesome 7x32s, what motivates you to continue jonesing for...

    which 10x42 : Nikon HG / GPO Passion HD / Maven B1.2 / Vortex Razor HD ?

    Hey Choc59, After birdwatching for decades with random, second-hand binoculars, a few of years ago I was able to plunk down 1k and get Nikon 8x42 HGs. I was/am very happy with them. At the time I compared them side by side with the Nikon 10x42 HGs. The greater magnification was completely...

    San Francisco birding suggestions

    As it happens I was at Tennessee Valley in Marin yesterday 10:30-1 or so and there wasn’t so much going on. Not the best time of day and I’m not a fantastic birdwatcher, but there wasn’t much to identify OR misidentify 🙂

    San Francisco birding suggestions

    Welcome in advance to SF. I would start early early morning at the Cliff House at the very western end of Geary Blvd, park in the lot and take the stairs down from the lot to the ocean overlook just north of the stairs. You can walk to different vantage points to ocean and beach watch. Then...

    GPO 10x50 - does anyone have them, use them?

    It's such a coincidence this thread woke up a few days ago: A few days ago I two Maven demo units: The B.6 10x50 and the B.2 9x45. I started off wanting 'good' 10x50s a couple of years ago. Ended up spending my 'good' money on Nikon 8x42 HGs. But I've still wanted quality very good, perhaps...

    GPO 10x50 - does anyone have them, use them?

    Would then the Maven B.2 9x45 be an equivalent to the Vortex 10x50 UHD (In quality of components and build, not in numbers obviously). If anyone’s tried all of these models. Thanks! L

    GPO 10x50 - does anyone have them, use them?

    What about Maven B.6 10x50s compared to GP0 HD 10x50s? Or the Vortex UHDs for that matter?

    Bay Area Work Trip - Birding Suggestions

    Welcome (in advance) to the Bay Area! The part of the Hayward Shoreline I most often visit (there are various roads in to various parts of that shoreline) is at the west end of West Winton Avenue. I saw black skimmers there a couple weeks ago and it is AMAZING to watch them do their thing...

    Eyeglasses - a few unqualified remarks

    This is a great thread. I have life-long farsightedness and astigmatism and can’t see anything without glasses. I am flummoxed by the fact I always have to adjust the separate right diopter when using binoculars. I just this past week got an updated prescription and still I have to adjust the...

    Torn between the ~$1000 options..

    "upgrade itch" - what a great, evocative, accurate phrase. I am wanting really good 10x50s in the 1k-1.5k range. I am for focused on reading about all the possibilities, reviews, comparisons, opinions, counter-opinions MORE than I am focused on...birdwatching! It's ridiculous but it is fun...

    Torn between the ~$1000 options..

    Re "what kind of language is appropriate and tolerated here," my tolerance for "15x56 being heavy is totally garbage" is much greater than my tolerance for "jap binos."

    GPO 10x50 - does anyone have them, use them?

    Thank you. I should have added: If you are regularly using the GPO 10x50s in the field, does the very small field of view strongly affect your experience? The eye relief is attractive as I wear glasses. The field of view for the Ultravids is greater but the eye relief much less than the GPOs...

    GPO 10x50 - does anyone have them, use them?

    I’ve read the couple-few reviews of these and other GPO HS binoculars, along with all the marketing info. Does anyone actually own and use these 10x50s? Can anyone offer their experience using them for birdwatching? I am stuck in the idea of getting 10x50s, and sight-unseen (ha!) I am stuck in...

    Looking for a scope

    I purchased the Nikon Fieldscope III non-ED along with a 20x60 eyepiece and a tripod from b & h photo (they are out of NY; I live in San Francisco, found it online, and purchased via the telephone). The scope body (w/o eyepiece) was back when and still is $519*. The eyepiece is listed for...

    Guides for your part of the world

    My wife has a Nat'l Geo guide that she says she prefers over Peterson's Western Birds. I much prefer the Peterson's over Nat'l Geo. I did purchase the Sibley Western Birds guide and now favor this over Peterson's. The quality of the plates are far superior to Peterson's, and, just at...

    The Elusive One

    Luckily I aspire to see species that are relatively (supposedly) common in my neck of the woods. I've never seen a yellow-headed blackbird. Also, we get a great influx of various gull species in the winter and winter-to-winter I'm a-workin' on my gull id skills. I aim to confidently see a...
