The bushnell 1500 will range most trees out to around 1050y with pretty much full sun, Early morning, before the sun rises you can pick up large trees out to 1500y. For deer i've found it's hard to pick them up passed 600y but around 66% of our deer population is black so lighter species might pick up a bit further out. The only thing I don't like about it is the Low-Light LED, When it comes on it makes it damn near impossable to find something in the FOV because it get washed out by the green light.
If you end up going for the Bushnell give The Optic Zone
a try, he had the best prices a while back when i ordered mine [img]/ubbthreads/images/graemlins/wink.gif[/img] .
