I bought a sytong HT 66 add on from East Anglia Optics used to have a pard but the sytong has more settings, day vision, black white night vision and green which is the anti glare night vision. Plus it’s simple to use to set up use x and y axis to put the dot center of the crossairs and the way you go. Also the buttons are so much better and quieter than the pard models! Plus there cheaper and personally I found the image clearer too
