I'm thinking about getting a nightvision scope to go for the old foxes that are not playing fair on the lamp i'm looking to spend up to around £1400. I would prefer to buy the product new.There seems to be more and more coming on the market now which makes choosing them more challanging and everyone is supposed to better than the other. I want to be able see foxes at about 300meters and see them ok. Some of the area's i would be going on i would be shooting at range of between 100 to 250 if this is possible. Any ideas on what options to go for?
