I have a Rangematic Mk 5 soooper-doooper 1000 yd optical rangefind.
This is the kind you commonly see in the sporting goods stores and at
gun shows. It has a separation of about 1 foot.
It is a pretty sorry unit. The optics are very bad. Instead of
split screen which is easy to use, it uses a colored filter, in this
case, yellow, for one image. Except under ideal conditions, the
yellow image is indistinguishable from the clear one.
Secondly, it has a rather cheap plastic dial that I'd have little
confidence in regarding stability. The scale is very non-linear and
is so coarse by 300 yards (50 yds, div) as to be pretty worthless.
I've found that I can estimate distance visually about as well without
the unit as with. I've never checked the calibration so I don't have
any idea as to accuracy.

The standard for long-range hunting is the Barr&Stroud rangefinder,
which comes in 500 and 1000 yard models, I believe, and is good to
+/- 1% at its maximum range. They run about $1000 if you can find
one. An optical rangefinder can be made from two riflescopes and
a metal bar to serve as the baseline, as detailed in a recent
Precision Shooting. Not having a prism or mirrors connecting the
two scopes, it would be less convenient to use than the Barr&Stroud,
but can be built for $300-$400 (and the scopes can be removed and
used for their intended purpose).

where a child might read it?
