Putting the bird in the centre of the circle (if we had a version without the central dot, of course) might be even better than merely pointing a dot at something near the bird, and telling everyone to look "1.5 m at the four o'clock position" for the bird.The linked example has a radius of 3.4°, which is 60 mil ... might be usable, though perhaps a bit on the large side. They mention that they can easily do custom patterns, though.As the lasers they sell for these optics are not "flashlight"-tyle self-contained units, that's not really a ready-to-use product yet, but maybe there's the potential for creating something that's tailored to meet the needs of birders <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Regards,Henning</blockquote>
