Just saying Pulsar thermal imager tells us very little

What model is it HD, XD, XQ, Helion or Accolade ?
What lens size - 22mm,38mm or 50mm ?
Does it have a built in rangefinder ?
All of the above information will be on the label attached to the thermal so it won't be hard to find

Also:
How old is it ?
Is it still under warranty ?
Is it fully operational?
Are you the original owner?
The more accurate information you provide, the more likely you are to find someone who wants to buy it.
Cheers
