Questions & Answers

Shopper : Does this model have a cross reticule to calculate distance?K T P : yes, and the scale is laid out in both axesit's there scale horizontal and vertical. i don't know what that scale is but i remember reading about it and how to use it in the pamphlet that came with the binocs. i'm quite happy with them btw. dust caps would be a lot better if they really kept out dust but i'm quite happy with the these glasses.
K T P : does this binoc have the magic threaded hole for mounting on a standard tripod / camera holder?ANDREW R : Unfortunately no, this unit requires an adapter (not included).
K T P : is the included strap the original fujinon floating strap? not pictured as in most pics of this binoc which show its built in lens caps and yellow floating strap.ROBERT S : It comes with a yellow, floating strap with "Fuginon" printed on it. I haven't tried it, but it looks like there's enough flotation in the strap to keep the whole combination from sinking.

Great binoculars - but with dust inside them?

Binoculars themselves are very good. Use them on the Chesapeake bay to spot birds (?and the fish the birds point out). Durable, bright and great optics. Reducing one star because the pair I got has dirt or dust INSIDE the optics somewhere that shows up as a small black spot. It?s not on the outside. Annoying but does not detract from the functionality.

Lightweight but check compass accuracy

Lightweight. Check the compass accuracy. Previous pair was several degrees off (probably a Fujinon issue rather than a seller issue).

Long term review

These binoculars provide excellent image quality and great quality feel for the money. I've had a pair for about 10 years now. A couple of years ago, I noticed some corrosion and mold on one side. They have never been dropped in the water but have been exposed to rain and salt spray. I recommend them for causal use or for a cruise of up to a couple of years but they may leak after extended use in a marine environment. Even so, they can be replaced every few years and still be cheaper than many other models.

super bright even for 50mm

1) yes the yellow floater strap you read about in other ads for these binox is indeed included. (why not in the pic??) so are batteries for the compass light. 2) the bushnell car window mount as mentioned on the same web page implies that it works with these binox, but you must also buy an adapter. (btw that bushnell window mount is just as good as if not better than my pricy manfrotto one) The female threads on the front of the binox are same thread pattern as sticks up from your tripod, so a very universal adapter should work nicely. I ordered the bushnell adapter having been pleasantly surprised by the quality of the window mount. i bought them at adorama because i saved a couple bucks vs other online sellers of the model #. adorama folks reading this please note that inclusion of tech info in the ads would be (and is, when it's there) greatly appreciated;-)
