Dont waste anymore time and buy Flir ps32 first. Then get nv. With flir get some type of kill light. You will pick up more with flir and get better at scouting.
With Nv you will also need a couple of ir lights....go to nigh calling forum for more on flir.
When you have the flir the pvs14 gives you a lot more wiggle shooting time then a light and the nv with ir will pick up the eyes when flir is in an area with lot of obstacle or heat on rocks, tree, ground etc...
Good luck
