I know NOTHING about guns/scopes, shooting, etc., but would like to give my husband a night vision rifle scope for Christmas. He would use this to shoot wild hogs, skunks, etc on our ranch. My limited internet research indicates a 3rd generation ATN is available for about $5000, and I'm guessing "day/night" means he could use the same scope without removing it and/or fussing a bunch at all times. Any advice as to whether or not this would be a good choice -- keeping in mind we are located in a teensie town somewhere in the middle of nowhere and Christmas is just five shipping days away -- would be most appreciated. Thank you.
