If you're like me, you like your money to go as far as possible. You want a product that works perfect every time and does what you need it to do, but doesn't cost an arm and a leg. When it comes to rangefinders, I have found one that fits the bill.
Vortex makes one rangfinder and they make it well. The Vortex Ranger 1000 Rangefinder, model # RRF-101 is capable of ranging targets to 1,000 yards plus. I say "plus", but Vortex only claims the rangefinder can range out to 1,000 yards. However, I have ranged a whitetail deer at around 1,100 with mine.
The Vortex Ranger 1000 is very compact at less than 4 inches in length. It has 6x magnification and the objective lens diameter is 22 mm.
By default, the rangefinder measures distance at a Horizontal Component Distance. Which is an angle compensated distance, but can be changed to Line-Of-Sight distance easily. The unit of measure can also be changed from yards (for those of you who played football) or meters (for those of you who ran track).
A very cool feature I like is the Scan mode. While in Scan mode, it continually scans and gives back distance readings as you move the rangefinder across terrain.
For the money, the Vortex Ranger 1000 can't be beat! It is what I use when I hunt.
