It depends what your looking for in a rangefinder. Vortex won't make it too 1000 yrds on nonreflective objects. Mine goes 600-750. The laser beam is also fairly large so when your ranging out aways it will pickup closer objects in the view and will give you a false reading. If you get a higher end range finder like a leica you will have more aaccurate readings because of the laser size.The vortex plus is lifetime warranty everyone else is lifetime on glass and 2 years on electronics
