Purchased one of these units tried it out for second time last night on air rifle with the intention of using it on rimfire when my application comes through fingers crossed,as it says one tin up to 300yds id on quarry no problem depending on conditions, very lightweight and easy to use,good clear image at night but found it a bit harder to use in day because of daylight reflection from screen,although still getting to know this unit I can see no problem using it for foxing out to 300yds,rabbits perfect,ratting perfect,although not cheap if you have a selection of rifles they are ideal for swa
