I hunt at night for them quite often, but not with night vision. I usually set out in a field they like to root in and listen. When I hear them in the field, I shine a spot light, with a red filter, over them and get them in the halo of the light, not direct beam. As long as you dont put a bright beam on them, they wont run. Aim and shoot. Or if it is a bright night with a good full moon. I do the same thing and take my 300 wby out with a big 55 objective. I can see them pretty well with the large objective and dont need a light when there is a full moon.
