That spark like a handy setup. I use a pulsar ld19a for a scanner and paid around $1400 for it. I can see a deer or coyote size heat blob at 3-400 yards but unless they are moving, hard to tell what they are till they get around 100 yards. Then I shoot with my armasight vampire nv scope. I cant tell the difference between coon and possums at 100 yards with the thermal but you can definitely see them. I also have the pulsar quantum xd50s and it is much clearer but the field of view is much more narrow than the 19, so you can identify heat sources better with the 50 but cant scan a field as fast as you can with the 19.
