If it's a NEW ONE your looking to purchase, have a look at
the Nikon RifleHunter 1000. I purchased one back in Feb.
and have used it in the field aprox 15 to 20 trips out.
Very impressed with it's all around use, which is primarily
Preditor hunting. Most, 99.9% of my shooting is under 400 yds,
and I've found it to be extremely accurate. I have ranged
Fur out to 762 yds with it, and the Neighbors Barn @ 1223 yds.
There are other Range Finders out there to be sure, but I can
only speak to the first hand Field knowledge I have with the
NRF 1000.
After looking at countless Range Finders in the 4 to 500$
range, reading countless reviews on most all of them,
(except for the RifleHunter 1000, as it's relatively new) and
the fact that Nikons RifleHunter 500 reviews were so
positive on that Model, my thinking was the 1000 could
only be an improvement over the 500.
I also tried to NOT LET THE FACT, that all the other Glass /
Optics I own are also Nikon, influence me in my decission
making process, but to be very honest here, I'm sure it was
also a deciding factor in my choosing the 1000.
Bottom line here is
I have NO REGREATS in my choice. It has EXCEEDED ALL
my expectations in every way, including the self adjusting
Low Light feature, and ease of use with Glasses, due to the
Eye relief.
Check them out, it may or may not be what your looking for
in a Range Finder. That's a decission only you can make.
