The Pard008 is very good, I have the LRF version which I use with the DE (the DE is much better than your 50 Blacksun) but only use it as a spotter/range unit for confirmation of a doubtful thermal target before shooting with the Thermion and pre-ranging hedges/trees when waiting for Fox. I don`t intend to use it as a weapon sight because I need it for what I have already mentioned, also the mount system and its alleged POI shift, although I am aware of someone on the NV forum who is in the process of bringing a reliable mount onto the market.
