Dear Jim:
I know your site talks about night vision [“Starlight” light amplification technology], but thermal night vision if you can afford it is far superior for hunting/perimeter defense/tracking. It doesn’t matter about movement or camouflage [since these can literally see body heat.] See: http://www.imaging1.com/thermal/Thermal_weapon_sight.html [4] and
