Thread: Magnification in Rangefinders (Vortex range)

Looking at getting a rangefinder, my first, for general purpose hunting (I am a sub 400m shooter) on farms, bush edges and some open country. Any pro's/con's of the different mag levels? For example looking at the vortex range they have 5x and 7x in the range. When would I find the 5x too little, and when would the 7x be too much mag? Thanks
