Still in the learning curve with mine they are very complicated for me,but I can see a rabbit easily at 300 yards .I just got the ATN Thor 4. Have not shot with it yet but using around the house and neighborhood shows great promise. The number of functions seems excessive at this point as I need to keep referring to the manual to see how to run everything. It has a really cool function to record before and after every shot you make and let you download to a computer or iPad .
now that flir is no longer selling to the civilian market the CS has sucked worseFlir PTS536. It died in less than a year later, took another year to get it repaired and returned.
Unit is quite good, CS suckola.
