Rangefinders are great, until the battery runs out right before you get a once in a lifetime shot at a unit 10 buck and you end up shooting under it because the damn thing had a body the size of a small elk making it look like it is 200 yards away instead of 350... But since then I buy scopes with mil-dots and practice mil-dot ranging. Also I have noticed that some scopes like the nikon buckmaster can give you a backup guestimate by carefully using the focus to dial in the focal distance. You have to use the same magnification each time just like mil-dot ranging, but using a scope with these features I can usuall be correct within about 5 to 10 yards every time. I would use the rangefinder money to put towards a better scope.
Camo is not very useful for deer in my experience hunting them in western Colorado. You gotta wear orange anyway, and most shots were made on deer that watched me get out of the truck, grab my gear and walk 50 yards from the road all before settling down and taking the shot. I am not a road hunter by any means, but 9 times out of 10 we would be driving back from a morning hunt and spot a heard 150 - 200 yards off the road. Not sure if navada will be the same.
