ATN 4k Pro ... do I need more than 14power for 13 yard rat shooting?

Yes it comes with one its ok out to about 100 yards it can be attached to the scope or any picatinny rail you may have.

Well its a 3-14 and since its digital the more magnification you add will distort more on your recording than in your eye piece but here is a doe that was probably about 10-15 yards. Scope wasn't mounted yet and was testing it out.

I wouldn't the field of view is better on the 3-14 its very simple to find them at 3x and zoom in fast with the side wheel if needed. 

Like he said you really don't want to use the digital zoom too much as it will distort and pixelate your video as you zoom in. It won't be noticed much at lower power but as the power gets higher it will be plain. Just the regular 3 power from the glass lens will be plenty at that range. The 3x14 will give you a much wider Field Of View than the 5x20 so it is better suited for what you are doing. The 5-20 is for the longer ranges.

I bought the 3-14 because I did not plan on shooting much over a hundred yards and figured I would need the extra field of view for ranges under 100 yards. I have been out playing with it but have not used it to hunt as yet.

Nothing needed in return just shoot me a pm and we can chat more about it.
